一种由甘油合成二氯丙醇的方法技术

本发明专利技术提供一种由甘油合成二氯丙醇的方法，包括：在固体酸催化剂的存在下，使甘油与有机酸进行酯化反应，生成有机酸甘油酯，将氯化氢通入有机酸甘油酯中进行氯化反应，反应完毕收集产物二氯丙醇。本发明专利技术提供的方法特点如下：（１）在固体酸催化下，甘油与有机酸酯化反应过程中带出反应生成的水，减少了在氯化反应过程中氯化氢的溶解，降低了对设备的腐蚀。（２）通过酯化反应后氯化活性高，反应速度快。特别在有压力条件下反应时间明显减少。（３）氯化氢用量减少，环境污染减少。

A process for the synthesis of two propanol from glycerol

The present invention provides a method including synthesis of two chloropropanols by glycerol: in solid acid catalyst in the presence of the glycerin and organic acid esterification to generate organic acid ester, hydrogen chloride in organic acid glyceride by chlorination reaction, after the reaction products were collected two chloropropanols. The invention provides a method of characteristics are as follows: (1) in solid acid catalysis, the reaction of water with glycerin and organic acid in the esterification process, a reduction in the chlorination reaction process of hydrogen chloride solution, reduce the corrosion of equipment. (2) the activity of chlorination is high and the reaction speed is fast after esterification. Especially under pressure, the reaction time is obviously reduced. (3) the amount of hydrogen chloride is reduced, and the environmental pollution is reduced.
