【Abstract】The synthetical route of p-tert-butyl benzoic acid (PTBA) and m-phthalic acid were studied under atmospheric pressure, which taked p-tert-butyltoluene (PTBT) and m-xylene as material, oxygen and 30% hydrogen peroxide as green oxidant respectively.In the experiment which oxidized p-tert-butyltoluene, the reaction under two kind of crafts were studied separately, which taked 30% hydrogen peroxide and oxygen as green oxidant, taked cobalt acetate and homemade catalyst as catalyst respectively. In t...

【Key words】 p-tert-Butyltoluene; p-tert-Benzoicacid; meta-Xylene; m-Phthalic acid; Liquid-phase catalytic oxidation;
