Abstract

Cyclohexane and homologues thereof are oxidised to dicarboxylic acids in the liquid phase and in the presence of a solvent by means of a gas containing oxygen and a catalyst comprising a mixture of an alkaline earth metal salt and a manganese salt. The formation of an intermediate aldehyde-acid is mentioned. In an example, air is introduced into an aluminium vessel containing a heated mixture of cyclohexanone, acetic acid, manganese acetate and barium acetate. Adipic acid is obtained by cooling the reaction mixture. The propionates, isobutyrates, chlorides and nitrates of manganese and of barium and the other alkaline earths are mentioned as catalysts. Organic acids, such as acetic, propionic, isobutyric, trimethylacetic, phenylacetic and methoxyacetic acid are the preferred solvents, but benzene and carbontetrachloride may be used. Specification 415,172 is referred to.
