直接酯化法制备棕榈酸异丙酯工艺路线探讨

Inquire into the Technology of Palmitic Acid Isopropyl Ester Prepared by Direct Esterification Meth

摘要: 在直接酯化法制备棕榈酸异丙酯中利用苯—异丙醇—水三相混合物组成恒沸剂带出水，同时以对甲苯磺酸替代浓硫酸作为催化剂使产率达到８５％，且降低了对搅拌和设备防腐的要求。

Abstract: The rate of preparing palmitic Acid isopropyl ester is enhanced to 85% by means of direct esterifcation, since Azeotrope containing benzene、isopropyl ester、water is used to bring out water and concentrated sulfuric acid replaced by p-methybenzene sulfonic acid as catalyst.At the sametime,the requirements for stirring and equipments antisepic are reduced.
