Abstract:

Simulation of Colored Waste Water Treatment Using Photo Fenton in Continuous System Waste water from coffee processing was treated by the Photo Fenton method. Experiments were carried out in a 2 liter batch reactor equipped with ultraviolet lamp for 4 hours. The synthetic waste water was made by dissolving 300 mg instant coffee in 1 liter water. Reagents used are 700 ppm H2O2 prepared from 30 % H2O2, and 15 ppm FeSO4.7H2O. The experiment was carried out at pH= 3. Prior to treatment, the color of the waste water was brownish yellow.

Textile liquid waste is waste from textile operations that contains high organic and inorganic elements. Organic and inorganic elements may pollute the environment if dumped straight into water. The breakdown of organic and inorganic elements in water by microorganisms produces a very poisonous chemical called Ammonia (NH3), which causes high TSS levels owing to the buildup of organic and inorganic materials. TSS levels in textile wastewater A were determined using the gravimetric technique, which involves weighing the suspended precipitate after it has been filtered using a vacuum pump and dr

Abstract:

Crystallographic structural analysis of four electronically diverse Willgerodt-type reagents is disclosed together with a solution-phase NMR analysis. These data reveal a plethora of intermolecular non-covalent interactions and confirm the expected T-shape geometry of the reagents. In all cases the I–Cl bonds are orthogonal to the plane of the aryl ring. This study provides important structural insights into this venerable class of dichlorination reagent and has implications for crystal engineering.

Abstract:

Decrease of mined coal quality results in deterioration of main quality characteristics of coal concentrates: ash content, moisture, calorific efficiency and sintering ability. Application of selective reagent modes of coals flotation is an effective method of solving the problem. Elaboration of the reagent modes should be based on a study of mechanism of reagents action on the coal surface. Study of the aromatic esters effect on the physicochemical and flotation properties of gas coals from the Komsomolets mine of the Kuznetsk coal basin accomplished. It was shown that the low natural floatab

Abstract:

The selectivity of the substitution reaction of phosphoryl chloride with organometallic reagents was investigated using NMR spectroscopy. This led to the discovery that the selectivity of the substitution reaction can be tuned by choosing a proper organometallic reagent. A phosphinate could be obtained by using a Grignard reagent whereas an organozinc reagent provided a phosphonate. Based on these results, one-pot synthetic methods for the preparation of phosphinates and phosphonates using commercially available starting materials were developed. Both methods allow the synthesis of a broad ran

Abstract:

Reaction of Me3SnLi with 1 equivalent of CuBr•Me2S, PhSCu, Me2(MeO)C—C≡C—Cu, or CuCN in tetrahydrofuran (THF) affords the (trimethylstannyl)copper(I) reagents Me3SnCu•Me2S (1) and [Me3SnCuY]Li (Y = PhS (2), Me2(MeO)C—C≡C (4), CN (5)), respectively. Similarly, treatment of a THF solution of Me3SnLi with 0.5 equivalent of CuBr•Me2S provides (Me3Sn)2CuLi (3), while reaction of n-Bu3SnLi with PhSCu (1 equivalent) gives [n-Bu3SnCuSPh]Li (6). Reagents 2 and 6 readily transfer (in a conjugate sense) the R3Sn group to conjugated enones (e.g. 7–9) and structurally simple enoates (e.g. 10), but do not r

Abstract:

Hypervalent iodine heterocycles represent one of the important classes of hypervalent iodine reagents with many applications in organic synthesis. This paper reports a simple and convenient synthesis of benziodazolones by the reaction of readily available iodobenzamides with m-chloroperoxybenzoic acid in acetonitrile at room temperature. The structure of one of these new iodine heterocycles was confirmed by X-ray analysis. In combination with PPh3 and pyridine, these benziodazolones can smoothly react with alcohols or amines to produce the corresponding esters or amides of 3-chlorobenzoic acid

Through-silicon via (TSV) technology is gaining popularity in 3D packaging and 3D integrated circuits. TSV baths are formulated with highly stable electrolytes that contain copper and sulfuric acid. Other components introduced into the bath in relatively small amounts are organic additives and chloride ions. This article will focus on a non-reagent metrology to efficiently monitor these components. The chloride concentration is determined from the chloride oxidation current using specific voltammetric parameters. Similar to analysis of suppressor, the measurement is made directly in the undilu

Abstract:

Redox-active guanidines are ideal proton-coupled electron-transfer (PCET) reagents, since they combine a high Brønsted basicity with a low and tunable redox potential. In this article, the development of redox-active guanidines (especially guanidino-functionalized aromatics, GFAs) in the last ten years is summarized, and their properties compared to other organic Brønsted bases and organic electron donors. First, some applications in organic chemistry that purely use the redox activity (formation of organic donor–acceptor materials and photochemical reductive C–C coupling reactions) are presen

Reactions of a mixture of dimethyl polysulfides (DMPS, CH3SxCH3, x = 3 – 8) with methyl- and phenylmagnesium halides are described. The type of product obtained was dependent on the molar ratio of DMPS to Grignard reagent. When a 6:1 methyl-Grignard to DMPS ratio was used, methanethiol and dimethyl sulfide were the major products obtained after acidification of the reaction mixture. Lesser quantities of methyl-Grignard favored the formation of dimethyl sulfide, dimethyl disulfide, and H2S. Experiments with a 6:1 phenylmagnesium bromide to DMPS ratio produced benzenethiol and phenylmethyl sulfi

Abstract:

A new chemoselective method for the synthesis of 2-aryl-1,3-oxazoles by deoxygenation of the corresponding N-oxides has been developed. As the deoxygenation reagent, a previously unknown complex of collidine with phosphorus trichloride in a 2:1 ratio has been used. The developed method enabled the preparation of a wide range of 2-aryl-1,3-oxazoles comprising various functional groups in good yields. The advantage of this reagent is its tolerance to nitro, methyl, hydroxyl, formyl, and acetyl groups, and double bonds. Due to chemoselectivity and availability of reagents, the method may be used
