Title substances are prepd. by liq.-phase oxidn. of methylbenzene in AcOH at elevated temp. with a transition-metal compd., with subsequent catalyst regeneration by oxidn. with O. The prepn. is accelerated and the yield increased by oxidn. in aq. AcOH contg. 7-25 vol% H2O and using 0.08-0.3 M phosphomolybdovanadium heteropoly acid H3+nPMo12-nVnO40 (I; n = 2-6) as the transition-metal compd. at 70-120° and 5-20:1 substrate-I molar ratio.
