METHOD FOR OXIDATION OF HYDROCARBON TO ACID Russian patent published in 2006 - IPC C07C51/31 C07C51/215 C07C55/14 

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to the improved method for oxidation of cycloaliphatic hydrocarbons and/or alcohols and ketones in liquid medium with a molecular oxygen-containing oxidizer to acids or polybasic acids. The reaction is carried out in the presence of manganese-base catalyst and organic acid compound of the general formula (I): HOOC-Ar-[R]_n wherein Ar means aromatic radical comprising aromatic cycle or some aromatic cycles in condensed form; n means a whole number 1, 2 or 3; R means radical of the general formula (II): wherein R1, R2 and R3 are similar or different and mean alkyl chain comprising from 1 to 4 carbon atoms, or fluorine, chlorine or bromine atom. In more detail, the invention relates to oxidation of cyclohexane and/or cyclohexanol/cyclohexanone to adipic acid with an oxidizer in the presence of aromatic organic acid and manganese-base catalyst. The yield and selectivity by adipic acid are at higher level with respect to yield and selectivity as compared with result obtaining with other solvents and catalysts.

EFFECT: improved oxidation method.
