摘要
研究了采用固体酸ＳｎＣｌ４·５Ｈ２ ＯＣ为催化剂，甘油和冰醋酸反应合成甘油三醋酸酯的最佳工艺条件，结果表明，当ｎ（甘油）∶ｎ（冰醋酸） ＝ １∶４，催化剂的用量为１－５ｇｍｏｌ 甘油，甲苯用量为２５ｍＬ，反应时间５ｈ 时，酯的产率可达９６％ 以上。该工艺产率高，工艺简，反应时间短，无腐蚀，无污染。
The optimun technological conditions were studied on the synthesis of glycerol triacetate by the reaction of glacial acetic acid and glycerol with SnCl 4·5H 2O/C as catalyst.The results showed that the yield was over 96% when glycerol:glacial acetic acid=1∶4(molar ratio),the amount of catalyst was 1.5g/mol of glycerol,the amount of toluene was 25mL,and the reaction time was 5h.This process has many advantages such as higher yield,simple procedure,shorter reaction period,non corrosive,non pollution,etc.
