Abstract

A novel catalytst system consistingof N-hydroxyphthalimide (NHPI) and cobalt salts for the oxidation of toluene to benzoic acid using molecular oxygen as the oxidant was firstly exploited. The experimental results revealed that the yields of benzoic acid catalyzed by NHPI-Co(acac)₂ and NHPI-Co(OAc)₂ can reach 55.5% and 41.2%, respectively. The influences of oxygen pressure, reaction temperature and time on the yields ofbenzoic acid were discussed. A possible reaction mechanism was proposed.

Key words: N-hydroxyphthalimide, molecularoxygen, toluene, benzoic acid, Co(OAc)₂
