Abstract:
Aliphatic carboxylic acids of formulae (Ib) R1-COOH(Ia) and R2-COOH wherein R1 is tertiary C4-20-alkyl and R2 together are -(CH2)n- with n=3 to 10, are produced by oxidizing an aliphatic or alicyclic ketone of the formula (II): wherein R1 and R2 are as defined above, with molecular oxygen in the presence of a soluble manganese (II) compound.
