ixtures, used in oxidation of alkylaromatic compounds // 2540276
FIELD: chemistry.SUBSTANCE: invention relates to a mixture for oxidation of an alkylaromatic compound, containing: an alkylaromatic compound, a solvent, a brome source and a catalyst, with the solvent containing carboxylic acid, containing from 1 to 7 carbon atoms, as well as a ionic liquid, selected from the group, consisting of an imidazole ionic liquid, pyridine ionic liquid, phosphonium ionic liquid, tetraalkylammonium ionic liquid and their combinations, and, optionally, water; with the solvent being characterised by a ratio of the ionic liquid to carboxylic acid, being in the range from 1:10 to 10:1 by weight; and the catalyst contains, at least, one of the group: cobalt, titanium, manganese, chrome, copper, nickel, vanadium, iron, molybdenum, tin, cerium and zirconium.EFFECT: application of the method makes it possible to regulate the amount of admixtures in the solid product of oxidation.9 cl, 1 tbl, 9 ex
ethod of oxidising alkyl aromatic compounds // 2524947
FIELD: chemistry.SUBSTANCE: invention relates to a method and a mixture for oxidising an alkyl aromatic compound. The mixture contains: an alkyl aromatic compound, a solvent, a bromine source, a catalyst and ammonium acetate; wherein the solvent includes a carboxylic acid having 1-7 carbon atoms and optionally water, and the catalyst substantially consists of at least one metal selected from cobalt, titanium, manganese, chromium, copper, nickel, vanadium, iron, molybdenum, tin, cerium and zirconium, present in form of acetates or hydrates thereof.EFFECT: present invention enables to obtain products of higher purity which enables to eliminate or minimise purification costs.10 cl, 1 tbl, 3 ex
