PROCESS FOR THE PRODUCTION OF KETONES

摘要

A process for the production of aliphatic or alicyclic monoketones or alicyclic diketones of the formula R¹-C(-O)-R² in which R¹ is a linear or branched C_1-10-alkyl group and R² is a linear or branched C_1-10-alkyl group or a phenyl group, or R¹ or R² together are -(CH₂)_m-[C(-O)]_n-(CH₂)_p-, wherein m and p independently are integers from 1 to 4 and n is 0 or 1, thus forming an alicyclic ring together with the carbonyl group of R¹-C(-O)-R² by oxidizing a secondary alcohol of formula R^1'-CHOH-R^2' in which R^1' and R^2' either have the same meaning as R¹ and R² above or, if R¹ and R² together are -(CH₂)_m-[C(-O)]_n-(CH₂)_p-, are together -(CH₂)_m-(CHOH)_n-(CH₂)_p- wherein m, n and p are as defined above, with a peroxy compound in the presence of a carboxylic acid and a manganese(IV) complex of 1,4,7-trimethyl-1,4,7-triazacyclononane.
