【摘要】 以树脂作催化剂,合成柠檬酸三辛酯。探讨了催化剂用量、反应温度、酸醇摩尔比和反应时间等因素对酯化反应的影响。结果表明:在150℃,酸醇摩尔比为1∶4.5,催化剂用量为柠檬酸质量的10%,反应1.5 h后,酯化率达到97%以上。催化剂的性能较好,便于与产物分离,可以回收使用。更多还原

【Abstract】 Synthesis of trioctyl citrate using resin as the catalyst.The main factors,including quantity of the catalyst,reaction temperature,mole ratio of reactants and reaction time were investigated.The results showed that: the esterification reaction was conducted at about 150℃ in the presence of resin using about 10% by weight of citric acid,mole ratio of citric acid to 1-octanol was l∶4.5,the yield was up to 97% after 1.5 h.The catalyst is easily separated from product and reusable.更多还原
