Abstract

FIELD: organic chemistry. SUBSTANCE: method involves the oxidation of toluene with air oxygen at 240-275 C under pressure 7.5-15 MPa in the presence of water and NaCO(2-6 N. concentration in the aqueous phase), at the volume ratio of toluene and mixture of HO and NaCO(1-5), by oxidation for 5-30 min followed by additional oxidation for 1-6 min. Then aqueous and organic phases were separated, aqueous phase is acidified, and the end acid is isolated. Method provides increase of benzoic acid yield from 12.2 to 91.5% output of process is increased from 0.023 to 0.41 kg/l x h. EFFECT: increased output of process, increased yield of product.
