The focus of this paper is on DFT studies of two classes of sulfuric acid derivatives: dithionic and peroxydisulfuric acids. Tautomers of proposed organic sulfuric acids are also investigated. DFT calculations indicate that the acidity of the proposed acids without any electron withdrawing groups ...
(C.I. Direct Blue 86), the first commercial phthalocyanine dye. Reaction of sulfonyl derivatives withaminesyield organic-soluble dyes in wide use in lacquers and inks. Solubilized phthalocyanine reactive dyes are used for bright turquoise shades that cannot be obtained with either azo or ...

PROCESS FOR PREPARING BENZENIC DERIVATIVES BY REACTING AN ACTIVE HALOGENOBENZENE WITH AN OXYGEN OR SULFURIC ANIONIC ORGANIC REAGENTA PROCESS FOR THE PREPARATION OF BENZENIC COMPOUNDS BY REACTION OF AN ACTIVE HALOGENOBENZENE WITH AN ANIONIC OXYGEN OR SULFUR ORGANIC REAGENT IS PROVIDED IN THE PRESENCE...
PMS slowly hydrolyses sulfuric acid and H2O2 in water and reacts slowly with TrOCs, mainly acting as the primary source of SO4•− in the system. •OH is a strong nonselective oxidant, which can diffuse rapidly in the system and react with various TrOCs, with a reaction rate range ...

Furthermore, greater amounts of cinnamic derivatives were found in this extract such as trans-cinnamic, p-coumaric, caffeic, and trans-ferulic acids, respectively (Table 2). More than benzoic derivatives as hydroxyl-benzoic acid, vanillin acid was also identified in both studied extracts, as ...
This mixture of lipids and lipid derivatives was characterized, and mixed with biosurfactants in different ratios, to simulate the extracts collected from fermentations with residual lipid impurities. 2.3. Analysis of Fatty Acids, Mono-, Di- and Triacylglyceride Concentrations Fatty acids, mono-, di...
