硫酸氢钠催化合成柠檬酸正丁酯

Synthesis of Tri-n-butyl Citrate by Sodium Bisulfate

在一硫酸氢钠催化下由柠檬酸和正丁醇合成了柠檬酸正丁酯。当柠檬酸、正丁醇和硫酸氢钠的物质的量比为125：11：1，在150℃温度下，回流4h时，酯化率达93．3％。

The tri-n-butyl citrate was synthesized by esterification of citric acid with butyl alcohol in the catalysis of sodium bisulfate.When the proportion of quantity of citric acid,butyl alcohol and sodium bisulfate was1.25∶11∶1,at the tem-perature of150℃,time ofrefluxing was4h,the rate ofester was93.3%.
