(Acyloxyalkyl)aromatic carboxylic acids arenproduced by partial oxidation of an alkyl-substitutednaromatic compound of the general formulan CHR 1 R 2 - Ar - (R 3 ) n n in which Ar is an aromatic ring; R 1 is H or alkylnhaving 1 to 3 carbon atoms; R 2 is H, alkyl having 1 ton3 carbon atoms or -OCOR 5 ; R 3 is alkyl having 1 to 4ncarbon atoms, -COOH, -CHO, -CH 2 R 4 or -COOR 5 ; n is anninteger from 1 to 5; R 4 is halogen, -OH or -OCOR 5 ; andnR 5 is alkyl having 1 to 4 carbon atoms, and ancarboxylic acid in the presence of oxygen and ancatalyst including an element of Group VIII of thenPeriodic Table. (Hydroxyalkyl)alicyclic carboxylicnacids are produced by hydrolysis/hydrogenation ornhydrogenation/hydrolysis of the (acyloxyalkyl)naromatic carboxylic acids. |
