▎ 摘  要

NOVELTY - Synthesis of benzyl ester involves reacting benzyl halide and carboxylate as raw materials under the action of solid graphene oxide-supported quaternary ammonium salt as a phase transfer catalyst in water as solvent at 80-120 degrees C for 3-8 hours, and stirring at 300-600 rpm. The molar ratio of carboxylate and benzyl halide is 1:1-2:1. USE - Synthesis of benzyl ester. ADVANTAGE - The method enables simple, economical and environmentally-friendly synthesis of benzyl ester with benzyl halide conversion rate of more than 99%, and selectivity of more than 97% using recyclable catalyst.
