浓硫酸改性活性炭催化合成柠檬酸三丁酯

Synthesis of tri-butyl citrate by using modified activated carbon as A catalyst

采用浓硫酸改性的活性炭作为催化剂,以柠檬酸和正丁醇为原料,合成了柠檬酸三丁酯(TBC)。确定了最佳合成条件为:以1 mmol柠檬酸为基准,催化剂用量6.0 mg,反应时间3.5 h,酯化率可达83.3%。

Using modified activated carbon by H_2SO_4 as catalyst,tri-butyl citrate was synthesized.The conditions of reaction were investigated.The results showed that.the esterification could be finished in 3.5 hours with 83.3 % yield under optimum conditions.
