摘要 研究了一种将苯直接羰基化合成苯甲酸的新型催化体系Co(OAc) 2 /CCl3 COOH/K2 S2 O8,考察了反应过程中催化剂、反应时间、温度、CO压力等因素对反应收率的影响 ,结果表明在优化的反应条件下 ,苯甲酸收率可达到 2 0 %以上 .同时给出了可能的反应机理 . A novel catalytic system Co(OAc)(2)/CCl3COOH/K2S2O8 was studied for direct carboxylation of benzene to give benzoic: acid. The effects of catalysts, reaction time, temperature and CO pressure were investigated. The results show that the yield of benzoic acid can be more than 20% under optimized reaction conditions. A possible reaction mechanism was proposed.
