【摘要】 以柠檬酸和正丁醇为原料,采用活性炭负载对甲苯磺酸催化合成柠檬酸三丁酯。确定了最佳合成条件为:以0.1 mol柠檬酸为基准,酸醇摩尔比为1∶4.1,催化剂用量0.6 g,反应时间3 h,酯化率可达96.7%。更多还原

【Abstract】 Tributyl citrate was synthesized with citric acid and n-butyl alcohol as raw materils using p-toluene sulphonic acid supported on active carbon as catalyet.The optimum conditions of synthesis were determined: molar ratio of acid to alcoho was 1:4.1,amount of catalyst was 0.6 g,reaction time was 3h based on 0.1mol tributyl citrate,the yield of esterification is up to 96.7%.更多还原
