[Objective] The aim was to explore the optimum synthesis technology of menthyl ester.[Method] With immobilized Ce4+ on macroporous resin as catalyst,the menthyl formate and menthyl acetate were synthesized with formic acid,acetic acid and menthyl ester as raw materials.Then their synthesis technologies were optimized through orthogonal test.[Result] When the mol ratio of alcohols-acids was 1.0∶(1.4-1.6),the reaction temperature was 125-135 ℃,the reaction time was 4-8 h and the dosage of catalyst was 1%-2% o...
