高纯度柠檬酸三乙酯的合成

Synthesis of Triethyl Citrate with High Purity

由柠檬酸和95%乙醇在混酸(柠檬酸质量分数3%,磷酸摩尔分数3%与苯磺酸混合)催化条件下回流,使用甲苯带水,合成得99.96%纯度柠檬酸三乙酯。并进行了中试试验。

Triethyl citrate with 99.96% purity was synthesized from citric acid and ethanol (95%) in the presence of 3 % phosphoric acid (wt), 3 % citric acid (mol) and benzene sulfonic acid, with toluene as the refluxing agent to bring out water. The medium-scale experiment was also conducted.
