Abstract:

Alkoxy group substituted compounds of acetanilide are found to have pharmacological and industrial importance. Synthesis of alkoxy substituted acetanilides via conventional thermal methods involves multi-step processes, formation of side products, and the poor yield of desired products. But, the vast literature studies reveal that electroorganic synthesis of alkoxy substituted acetanilide derivatives would be effectively carried out through electrochemical oxidation methods. The direct substitution of the ethoxy (alkoxy) group onto the aromatic ring, an electrophilic substitution, has not been attempted so far. This concept is taken as a preparatory attempt to find an alternative method to the tedious chemical route and to invent a direct method of introducing the ethoxy groups into the aromatic ring in a single step. A polarization study on acetanilide with ethanol as an electrolyte is carried out on platinum and graphite anodes to find out the oxidation potentials. Electrochemical ethoxylation of acetanilide at the platinum electrode is done by the Potentiostatic method using the oxidation potentials. The products are separated using preparative TLC and purified with suitable solvents. The products are characterized by UV, IR, NMR, and Mass spectra.

Abstract:

Purpose Corrosion and corrosion inhibition of alloyed zinc electrode were investigated in neutral chloride solution using electrochemical techniques. The purpose of this study is to study the corrosion inhibition of acetanilide and para hydroxy acetanilide as organics inhibitors for corrosion control of alloyed zinc electrode in NaCl 3 per cent solution. Design/methodology/approach A volt lab PGZ 301, assembled using alloyed zinc working electrode, a platinum counter electrode and a saturated calomel electrode as the reference electrode, was used in the experiment. This research was conducted using potentiodynamic polarization and electrochemical impedance spectroscopy techniques. Findings Acetanilide, para hydroxy acetanilide and their mixture provided inhibitions efficiencies of 88 per cent at 40 ppm, 87 per cent with 80 ppm and 99.86 per cent with (40 ppm AC + 80 ppm PHA), respectively. The study also discusses the corrosion inhibition mechanism of the protective layers. The adsorption of acetanilide and para hydroxy acetanilide on metal surface obeyed Langmuir’s adsorption isotherm. Polarization measurements showed that the acetanilide and the para hydroxy acetanilide, and their mixture acted as cathodic inhibitors in NaCl solution, and the inhibitor molecules followed physical adsorption on the surface of alloyed zinc. Originality/value The other new inhibitors which are very efficient inhibitors and to be applied in the field of prevention and control against corrosion.

Abstract:

Acetanilide or N-phenylacetamide is an aromatic compound having phenyl ring attached to an acetamido group (–NHCOCH3). In 1886, acetanilide was introduced as an analgesic and antipyretic drug into medical practice by A. Cahn and P. Hepp. Since then, many acetanilide derivatives have been found to have antimicrobial, analgesic, anti-inflammatory, antipyretic, antioxidant, anticonvulsant, anti- cancer, antihyperglycaemic and antimalarial activities. Acetanilide also plays an important role in the synthesis of a number of chemicals as intermediates and precursors. The chief objective of the present article is to highlight the chemistry and pharmacological aspects of various derivatives of acetanilide and their pharmacological activities to assist the future discovery of more efficacious derivatives with less toxicity.

Abstract:

The intramolecular hydrogen bonding formation in ortho-substituted compounds of Acetanilide, ortho-hydroxy Acetanilide and ortho-nitro Acetanilide, was investigated using Density Functional Theory (DFT), Møller-Plesset second-order (MP2) method and "Atoms in Molecules (AIM)" theory. It was found that in each case, the cis isomer is more stable than the trans isomer and ortho-nitro Acetanilide forms a stronger hydrogen bond than ortho-hydroxy Acetanilide. The effects of hydrogen bonding on structural parameters of the considered systems were studied using Becke's functional (B3LYP) and at the ab initio MP2 level in conjunction with different basis sets and suitable structural factors. The results are in agreement with the results of AIM theory.

Abstract:

Field studies were conducted from 1984 to 1986 to assess cabbage injury and yield response to several acetanilide herbicides. When incorporated, metolachlor significantly injured cabbage and reduced yields while post-transplant applications caused foliar flecking but did not reduce yields. Crop injury from pretransplant applications of 4.4 kg ai/ha was significant for all herbicides in both 1985 and 1986. Although total yields in 1985 and 1986 were comparable, maturity was delayed in 1986. With few exceptions, the acetanilides did not differ in either injury or yield-reducing potential. However, compared to trifluralin, metolachlor reduced yields in both years and at both rates.

Abstract:

Abstract One acetamide and 5 acetanilide herbicides are currently registered for use in the United States. Over the past several years, ethanesulfonic acid (ESA) and oxanilic acid (OA) degradation products of these acetanilide/acetamide herbicides have been found in U.S. ground waters and surface waters. Alachlor ESA and other acetanilide degradation products are listed on the U.S. Environmental Protection Agency's (EPA) 1998 Drinking Water Contaminant Candidate List. Consequently, EPA is interested in obtaining national occurrence data for these contaminants in drinking water. EPA currently does not have a method for determining these acetanilide degradation products in drinking water; therefore, a research method is being developed using liquid chromatography/negative ion electrospray/mass spectrometry with solid-phase extraction (SPE). A novel chromatographic separation of the acetochlor/alachlor ESA and OA structural isomers was developed which uses an ammonium acetate–methanol gradient combined with heating the analytical column to 70°C. Twelve acetanilide degradates were extracted by SPE from 100 mL water samples using carbon cartridges with mean recoveries &gt;90% and relative standard deviations ≤16%.

The energy-spectra of nonlinear vibration of molecular crystals such as acetanilide have been calculated by using discrete nonlinear Schrödinger equation appropriate to the systems, containing various interactions. The energy levels including higher excited states are basically consistent with experimental values obtained by infrared absorption and Raman scattering in acetanilide. We further give the features of distribution of the energy-spectra for the acetanilide. Using the energy spectra we also explained well experimental results obtained by Careri et al..

Abstract:

Germination inhibition activity of N-aryl hydroxamic acids and acetanilide analogues was measured on lettuce seeds (Lactuca sativa). Lipophilicity of the compounds was determined by HPLC. A correlation between lipophilicity values and percentage of germination inhibition was established. A model mechanism of action for auxin was used for analyzing the effect of the substituent at the alpha carbon atom (Cα) on the polarization of hydroxamic and amide functions in relation to the germination inhibition activity observed. Results suggest that the lipophilic and acidic properties play an important role in the phytotoxicity of the compounds. A test with the microalga Chlorella vulgaris was used to evaluate the potential herbicide activity of the hydroxamic acids and acetanilides.

Abstract:

Background: Bromination is a key reaction in the chemical industry since the organobromines find application in diverse fields like pharmaceuticals, dyes, fire retardants, and as intermediates in chemical synthesis. Objective: To carry out green, in-situ bromination of acetanilide in an aqueous medium using micellar SDS as a catalyst. Methods: Bromination of acetanilide in-situ using potassium bromide as a non-corrosive source of bromine, ceric ammonium nitrate as oxidant, micellar solution of sodium dodecyl sulphate (SDS) as catalyst and water as solvent. Results: p-Bromoacetanilide was prepared in excellent yields at room temperature using green chemistry principles. Conclusion: The presented method provides a fast and environmentally safe route for the preparation of p-bromoacetanilide from acetanilide. It avoids the use of volatile, corrosive, and hazardous substances like liquid bromine and acetic acid. The use of water makes it safer and free from hazardous organic solvents. This reaction can be suitably adopted at the undergraduate level and may find use in the synthesis of commercially important bromo compounds.

We calculate the quantum energy spectra of molecular crystals, such as acetanilide, by using discrete nonlinear Schrodinger equation, containing various interactions, appropriate to the systems. The energy spectra consist of many energy bands, in each energy band there are a lot of energy levels including some higher excited states. The result of energy spectrum is basically consistent with experimental values obtained by infrared absorption and Raman scattering in acetanilide and can also explain some experimental results obtained by Careri et al. Finally, we further discuss the influences of variously characteristic parameters on the energy spectra of the systems.

Abstract:

The aim of the study synthesis of new heterocyclic derivatives (six and five ring) from acetanilide. Firstly the chalcones have been synthesized from the reaction acetanilide with aromatic aldehyde [ 2-nitrobenzaldyhade, 4- dimethylaminobenzaldehyde, 2-naphthaldehyde ] in dilute solution of ethanolic sodium hydroxide at room temperature. This reaction occurs depending on Claisen Schmidt condensation, then a new oxazine and thiazine derivatives (six ring) have been synthesized by the reaction chalcones with urea and thiourea. Finally the synthesized chalcones were reacted with hydrazine hydrate to produce new pyrazol derivatives (five ring). All derivatives were characterized by physical properties, FTIR, 1H-NMR and 13C-NMR spectra.

Abstract:

In over-the-counter headache medications, N-acylated aromatic amines—those with an acyl group, RCO-substituted on nitrogen—play a significant role. Drugs that you can get over the counter don't require a prescription. Acetanilide, phenacetin, and paracetamol (acetaminophen) are the so-called "aniline derivatives" or "aniline analgesics," of which paracetamol is essentially the only survivor. Acetanilide is the precursor to both phenacetin and paracetamol. An industrial chemist may refer to paracetamol as 4-hydroxyacetanilide or para-hydroxy acetanilide. It is a crucial end product and precursor for synthesising several other organic chemicals. It has become well-known as an analgesic because of its accessibility, but when overeating or in combination with other foods or medications, it can have severe side effects. This article discusses the historical transformations this significant molecule has undergone up to this point, how chemists prepare it, the processes it goes through when other precursors are present, how much it doses, its adverse effects, and how it is used. This is a beneficial medication that should be handled carefully because it can become poisonous when used with other medicines, including warfarin.

Abstract:

The effect of α-, β-, and -γ-cyclodextrins on the quantum yield for the formation of o- and p-aminoacetophenone from the photolysis of acetanilide at 254 nm was determined. There is an increase in the ratio of o/p products when cyclodextrins are added and the total quantum yield is about the same as in water in the presence of γ-CD, higher with β-CD, and lower with α-CD. The association constants between acetanilide and CD were determined and the values are 22.7 M−1 and 30.7 M−1 for α- and β-CD respectively. The quantum yields for the formation of o- and p-aminoacetophenone were measured. The rearrangement occurs in water and in the included acetanilide. The quantum yields for the formation of o-aminoacetophenone and p-aminoacetophenone from the included substrate could be calculated for α- and β-cyclodextrin. Comparing these values with those obtained in water, it is concluded that there is some steric inhibition for rearrangement at the para position when α-cyclodextrin is the host, whereas with β-cyclodextrin the less polar microsolvent effect is responsible for the increase in the total quantum yield relative to water.

Abstract:

The degradation of14C-labeled metolachlor, acetochlor, and pretilachlor in control and soils with 10-yr metolachlor- history or 3-yr butylate history was studied by monitoring the evolution of14CO2in soil biometer flasks. The degradation rate of14C-phenyl-labeled metolachlor was similar in soils with 0- and 10-yr metolachlor history over 52 d.14C was released from carbonyl-labeled metolachlor about 40% faster than from phenyl-labeled metolachlor in both soils. Soil sterilization by autoclaving reduced significantly the metolachlor degradation rate in both soils. Degradation of14C-labeled EPTC in soils with 3-yr butylate history was much faster than in soils with no history. Soil sterilization reduced the EPTC degradation rate, confirming microbial degradation. The degradation rates of acetochlor, metolachlor, and pretilachlor were similar in soils with and without butylate history. Most of the14C that remained in history and nonhistory soils was extractable with ethyl acetate or sodium hydroxide. Three major metabolites of metolachlor and EPTC were detected by thin-layer chromatography (TLC) of extracts from both soils. In contrast to the situation with carbamothioate herbicides, soils exposed repeatedly to metolachlor or other acetanilides are not prone to become adapted to these herbicides. Soils with carbamothioate history did not exhibit any apparent cross-adaptation toward acetanilide herbicides.

Abstract:

Seasonal residues of an acetanilide and triazine herbicide were monitored in ridge, conventional, and zero tillage systems. Alachlor (2-chloro-2′,6′-diethyl-N-(methoxymethyl)acetanilide), and atrazine (2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine) residues were less than 8% of the spring application concentration at the end of the growing season. Moldboard plowing in the fall reduced herbicide residues in spring because of soil dilution by plowing to greater than the sampling depth. Ridge tillage systems had higher spring residues apparently because of reduced herbicide dissipation on the drier ridge tops. The higher residues of the triazines on ridge tops may be injurious to triazine sensitive crops. Key words: Herbicide, till-plant, ridge tillage, des-ethyl atrazine

Abstract:

The melting point is very useful information for identifying an unidentified organic substance. It is also helpful to define the purity of the substance. Pure substances have a melting point range of 1-2oC, while the impurities lower the melting point and increase the melting range. In a mixture of two substances, the melting point can be calculated by creating a two-phase melting diagram. The lowest temperature at which the melting point of a mixture can be reduced is called the eutectic point. The melting point is measured on a special heated apparatus using a glass capillary tube. The sample is placed in the tube, which is heated in the device. In the following study, the melting point of an unknown organic compound was measured by the fast and the slow rate heating method. The melting point of the sample showed that the chemical compound to be identified was either acetanilide or 4-nitrophenol. Equal amounts of the unknown substance and acetanilide were mixed, and the melting point was estimated for the mixture. If the mixture has a lower melting point compared to that of the unknown compound, then the two compounds are different, and one acts as an impurity to the other. The mixture had a similar melting point to that of the unknown compound, and therefore the unknown compound was identified as acetanilide C6H5NH(COCH3).

Abstract:

A thorough, systematic study into the effect that structurally related impurities have on both the process and product quality during the crystallization of an active pharmaceutical ingredient is presented. The presence of acetanilide and metacetamol influences the crystallization and product quality of paracetamol. Where high concentrations of either impurity were present in the crystallization feed, product recovery decreased by up to 15%. Acetanilide is included in the final product through adsorption onto the particle surface in concentrations up to 0.79 mol%, which can be reduced to acceptable levels through product reslurrying. The presence of metacetamol results in much higher concentrations—up to 6.78 mol% in the final product, of which approximately 1 mol% is incorporated into the crystal lattice, resulting in the perturbation of the unit-cell dimensions. The incidental crystallization and subsequent isolation of metastable Form II paracetamol increased product purity in the presence of a low metacetamol concentration. This metastable product converts to stable paracetamol Form I through reslurrying, offering an efficient metacetamol impurity rejection route. The morphology of the product is modified consistently by both impurities. An elongation of the normal prismatic shape is observed, which in the extreme case of high metacetamol contamination results in the isolation of fine, fragile needles. This problematic morphology is also improved by a reslurrying of the crystallization product to give a more equilateral shape. This systematic study of the influence of acetanilide and metacetamol on the crystallization of paracetamol builds a well-rounded picture of the concomitant impact of impurities on the principal quality attributes of a crystallization product.

Abstract:

ABSTRACT A bacterial strain capable of growing on propachlor (2-chloro-N-isopropylacetanilide) was isolated from soil by using enrichment and isolation techniques. The strain isolated, designated GCH1, was classified as a member of the genusPseudomonas. Washed-cell suspensions of strain GCH1 accumulated N-isopropylacetanilide, acetanilide, acetamide, and catechol. Pseudomonas strain GCH1 grew on propachlor with a generation time of 4.2 h and a rate of substrate utilization of 1.75 ± 0.15 μmol h−1. Gene expression did not require induction but was subject to catabolite expression. Acetanilide was a growth substrate with a yield of 0.56 ± 0.02 mg of protein μmol−1. GCH1 strain cells were immobilized by adsorption onto a ceramic support and were used as biocatalysts in an immobilized cell system. Propachlor elimination reached 98%, with a retention time of 3 h and an initial organic load of 0.5 mM propachlor. The viability of immobilized cells increased 34-fold after 120 days of bioreactor operation.

Abstract:

The acetanilide herbicides alachlor [2-chloro-N-(2,6-diethylphenyl)-N-(methoxymethyl)acetamide], metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl) acetamide], the ethyl ester of diethatyl [N-(chloroacetyl)-N-(2,6-diethylphenyl)glycine], or H-26910, the isopropyl ester ofN-(chloroacetyl)-N-(2-methyl-6-ethylphenyl)glycine, failed to inhibit yellow nutsedge (Cyperus esculentusL. ♯ CYPES) tuber sprouting in petri dishes. At 3.5 and 0.35 μM, all herbicides inhibited growth of newly emerging shoots. There was no significant difference in activity among alachlor, metolachlor, diethatyl ethyl, and R-26910 on yellow nutsedge sprouts grown in petri dishes. In soil, metolachlor and alachlor were equally effective for yellow nutsedge control. Both were more effective than H-26910 at high levels of soil organic matter. Diethatyl ethyl was least effective at all levels of soil organic matter. For all herbicides evaluated, activity decreased with increased levels of organic matter in the soil. For acetanilide herbicides to be effective on yellow nutsedge, they needed to be in the soil zone, above or at the level of the tuber.

Abstract:

Cyclodextrins act as molecular reactors to change the ratios of the products of reactions of anisole, acetanilide, 3-methylanisole, and 3-methylacetanilide with pyridinium dichlorobromate. With anisole and acetanilide, bromination at the para position is favoured over ortho substitution, and the effect is greatest with α-cyclodextrin. In the reactions of the methylanisole and methylacetanilide, the cyclodextrins afford higher yields of monobrominated products and less of the di- and tribromides, and β-cyclodextrin has the greatest effect. These outcomes can be attributed to inclusion of the substrates within the cyclodextrins restricting access of the reagent adjacent to the methoxy and acetamido groups. The yields of 4-bromoanisole, 4-bromoacetanilide, 4-bromo-3-methylanisole, and 4-bromo-3-methylacetanilide are thus increased from 73 to 94, 55 to 98, 37 to 86, and 39 to 72%, respectively. Perhaps more significantly, the quantities of the corresponding by-products are substantially reduced, from 27 to 6, 45 to 2, 63 to 14, and 61 to 28%. Since the reactions occur readily in water at ambient temperature, the cyclodextrins make them very efficient.

Abstract:

A significant class of compounds with a variety of biological applications is sulfonamides. The present work deals with the synthesis of 4-amino-N-arylbenzenesulfonamide derivatives (1-8) by the reaction of acetanilide-4- sulfonyl chloride and 4-substituted arylamine followed by hydrolysis to deprotect the acetyl group and give free amino group. Using disc diffusion, the synthesized derivatives were tested for in vitro antibacterial activities against Pseudomonas aeruginosa and Staphylococcus aureus. Ampicillin was used as a reference standard drug. Prediction of chemical toxicity was determined by ProTox-II, all compounds exhibited inactive organ toxicity model report. The ProTox-II application was used for endpoint LD50 (1200-5000 mg/kg), and toxicity classes (class 4-5) were reported. The results of this study revealed that some sulfonamide derivatives have good antibacterial activity and the remaining compounds showed low inhibition activity based on the substitutions on the aromatic ring. Antibacterial activity indicated that the electron-withdrawing group substituted phenyl ring sulfonamide derivatives (6-8) are more active than the remaining compounds..

Abstract:

Abstract: Many attempts were undertaken to modify this drug at the phenyl ring, acetamido group, and hydroxyl group in an effort to boost its efficacy, hide its bitter taste, and lessen its toxicity after it proved effective in the market as an over-the-counter antipyretic and analgesic. Paracetamol uses a variety of methods to lower body temperature. Chemically speaking, paracetamol is 4-hydroxy acetanilide and has a solid safety record. Chemical reactions based on nanoparticles are beginning to take the place of bulk material-based reactions. Owing to its many benefits, including the capacity to easily introduce multifunctionality, increase chemical activities, photochemical stability, and the conversion of partials into nano dimension, In this work we propose Tetra-o-acetyl-B-D-glucosyl N-acetyl-4-hydroxyl acetanilide have been synthesized for the first time by the interaction of Tetra-O-benzoyl-B-D-glucosyl isothiocyanate and Paracetmol. All the synthesized compounds were characterized on the basis of elemental analysis and XRD studies. The polarimetric study of the title compounds has been carried out.
