| Abstract: | Ethyl stearate was synthesized by the reaction of stearic acid and ethanol over the catalyst NaY molecular sieve supported organic phosphonic acid NaY/OPA. The influences of the dosage of the catalyst NaY/OPA, the ratio of alcohol/aci reaction time and reaction temperature were investigated. The optimized reaction conditions were 2 g of catalyst, 4：1 （molar ratio） of alcohol/acid, 4 h of reaction time at 100℃, and the relevant reaction conversion ratio could reach 70.1%. |
