FIELD: chemistry.
SUBSTANCE: present invention relates to a method of oxidising an alkyl aromatic compound, which includes contacting an alkyl aromatic compound, a solvent, a bromine source, a catalyst and an oxidant to obtain a product containing at least one of the compounds: aromatic alcohol, aromatic aldehyde, aromatic ketone and aromatic carboxylic acid. The pH of the solvent is at least 1.0-5.0 and said solvent contains at least one ionic liquid and a carboxylic acid.
EFFECT: disclosed method reduces content of impurities and/or improves the colour of the product.
