The main products of p-tert-butyltoluene(PTBT) oxidation reaction are P-tert-butyl benzaldehyde(PTBD) and p-tert-butyl benzoic acid(PTBA), they are important intermediates, which are widely and extensively used in organic synthetic industry and fine chemical products industry. This paper is dedicated to investigating the catalysis of the liquid-phase oxidation of PTBT by using Co(Ⅱ) complex compound, Co(Ⅲ) complex compound, Co(Ⅱ) and Mn(Ⅲ) complex compound with different proportions and CoSBA-15as catalysts...
