Abstract:

In Mexico and in the world, a problem of contamination in domestic water is due to petroleum derivatives such as waste motor oil (WMO), whose chemical composition is aliphatic and aromatic hydrocarbons. An ecological solution is to biostimulation with extracellular enzimes of Pleurotus florida and mineral solution to eliminate both by the aerobic native heterotrophic microbiota. The objective of this research was to analyze the bioremediation of domestic water polluted by benzene of WMO with an extract of P. florida and mineral solution. In that sense, P. florida was grown in straw with lignin

Abstract:

Removal of benzene and effects of various parameters on the removal efficiency in the aqueous solution with plasma are studied. Results indicated that the degradation rate can be considerably raised by prolonging the discharge time, removal proceeded faster when the treatment was conducted in alkaline or acidic than in neutral media. Fe2+ shows an evident accelerated effect on the benzene elimination, and the presence of H2O2 benefited the degradation. It is demonstrated that the hydroxyl radicals were the most responsible oxidants in the benzene degradation. The major intermediate products re

A new chloride anion receptor, derivatized oligoethylene oxide CF3SO2 substituted tetraamine (3), was synthesized.

However, when compound (3) was added to a benzene solution containing the solid dye compounds, the color of the solution immediately turned to dark blue, and the intensity of the color proportionally increased with the concentration of (3).

The equilibrium amount removed by SWCNTs (B: 9.98 mg/g and T: 9.96 mg/g) was higher than for MWCNTs and HCNTs. Toluene has a higher adsorption tendency on CNTs than benzene, which is related to the increasing water solubility and the decreasing molecular weight of the compounds.

Using gelatin as dispersant, liquid paraffin as porogen, novel hypercrosslinked polymeric adsorbents of LM-5 and LM-6 were prepared by post-crosslinking reaction with phenol and 2-naphthol, respectively. Bromoethane was used as crosslinking reagent to substitute poisonous organic compound of chloromethyl methylether. 2-Naphthol was used in the post-crosslinking reaction to enhance phenolic hydroxyl group content. The experiments of selective adsorbing aniline on resins in mixture solution, which consisting of benzene and aniline, show that the adsorption of aniline and benzene on LM-6 in aqueo

Abstract:

Reaction of 4-methyl-2,6-diphenylphenol (11a) with nitrogen dioxide in benzene solution gives the polysubstituted cyclohex-2-enones (14), (15), (16), (17) and (18) via the 4-nitro dienone (13). The reversibility of the 4-nitro dienone (13)/4-hydroxy dienone (19) conversion under these reaction conditions is demonstrated. Reaction of 4-nitro-2,6-diphenylphenol (11b) with nitrogen dioxide in benzene solution gives the C2-epimeric 2,6-dihydroxy-4,5-dinitrocyclohex-3- enones (32) and (33) via the 6-nitro-6-phenyl dienone (12b). X-ray crystal structure analyses are reported for compounds (14), (15)

Abstract:

Anhydrous Ga[GaBr4] is readily dissolved in benzene. The resulting solutions show discrete 71Ga NMR signals for Ga(I) und Ga(III) centers. Narrow line-widths of the former indicate a small electric field gradient of the Ga(I) nucleus due to almost spherical shielding by the 4 s2 lone pair of electrons.Crystals obtained from the benzene solution on cooling have the stoichiometry [(C6H6)2Ga · GaBr4]2 ·3 C6H6, and are isomorphous with the analogous chloride compound: a = 9.390(2). b = 10.847(1), c = 13.118(2) Å; α = 85.54(1). β = 102.91(1). γ = 105.62(1)°; triclinic, space group Ρ1̄, Z = 1.The ce

Abstract:

Here we present simple fluorophores based on the pyridine core, obtained with straightforward synthetic methodologies. These compounds present in solution absorption maxima in the UV region and fluorescence emission of between 300 and 450 nm, depending on the solvent and chemical structure of the fluorophore. The nature of the solvent was shown to play a fundamental role in their excite-state deactivation, which allowed successful exploration of these compounds as optical sensors for benzene and fuel adulteration in gasoline. In ethanolic solution, upon the addition of benzene, in general the

Abstract:

Slow co-crystallization of a solution of benzene-1,3,5-tricarboxylic acid with a large excess of 4-hydroxypyridine produces an interpenetrating, three-dimensional, hydrogen-bonded framework consisting of three 4-pyridone and one benzene-1,3,5-tricarboxylic acid molecules, C9H6O6·3C5H5NO. This structure represents an orthorhombic polymorph of the previously reportedC-centered, monoclinic structure [Campos-Gaxiolaet al.(2014).Acta Cryst.E70, o453–o454].

The title erbium coordination polymer, {[Er2(C8H4O4)3(H2O)2]·H2O} n , was obtained by the hydrothermal reaction of ErCl3 with benzene-1,3-dicarboxylic acid (1,3-BDC) in alkaline aqueous solution. Each of the two crystallographically independent ErIII ions is seven-coordinate and has a distorted pentagonal–bipyramidal geometry. One Er centre is coordinated by seven O atoms from six 1,3-BDC ligands and the other Er centre is surrounded by five O atoms from five 1,3-BDC ligands and two water molecules. The bridging ligands, which have two different coordination modes, link the metal centres to fo

Abstract:

The process of the interaction of benzene with sodium hypochlorite in a model environment under the action of ultrasonic radiation of different power and under the metered supply of an oxidant solution was investigated. The course of the process was evaluated by the change in the value of the redox potential of the medium over time. By the method of spectrophotometric analysis, it was established that as a result of interaction with sodium hypochlorite in cavitation fields, almost complete mineralization of benzene occurs. It is shown that the oxidative destruction of benzene mainly occurs due

Abstract:

In benzene solution the position of the 1H NMR signals of sulfanes, H2Sn, strongly depends on the sulfur chain length and on the sulfane concentration. Under proper conditions all sulfanes in a mixture are characterized by well-resolved NMR signals showing a downfield shift with increasing length of the sulfur chain. The shift differences between the higher homologues ( n > 8 ) remain nearly constant, thus allowing the assignment of the signals up to H2S35 and the determination of the complete sulfane distribution in crude oils. In sulfane mixtures without solvent as well as in CS2 and CCl4

The capacity of organically modified Montmorillonite (MMT) clay to adsorb nonpolar organic compound (benzene) in an aqueous solution, was investigated under the batch process.
