METHOD FOR SIMULTANEOUSLY PRODUCING P-ETHYLBENZOIC ACID AND epsi-CAPROLACTONE

摘要

PROBLEM TO BE SOLVED: To provide a method for simultaneously producing p-ethylbenzoic acid containing little amount of per p-ethylbanzoic acid andε-caprolactone in good selectivity in simultaneously producing p-ethylbenzoic acid andε- caprolactone by co-oxidizing p-ethylbenzaldehyde and cyclohexanone with molecular oxygen. SOLUTION: This method for simultaneously producing p-ethylbenzoic acid andε-caprolactone comprises using raw materials in 0.5-30 moles of cyclohexanone to 1 mole of p-ethylbenzoic acid and reacting them in the presence of a metal catalyst under 0.5-5 PaG reaction pressure range and in 30-55 deg.C reaction temperature range.
