增稠剂PEGS的合成及其在纺织品中的应用

Synthesis of Thickening Agent PEGS and the Application in Textile

本文用直接酯化法引入复合催化剂并减压除氧通氮保护,合成了色泽浅且具有显著增稠作用的非离子型表面活性剂聚乙二醇双硬脂酸酯PEGS,产率高达99.5%;并介绍了PEGS能替代脂肪醇聚氧乙烯醚(AEO)使用,也可以根据需要的HLB值复配表面活性剂,成为高效的纺织印染助剂。

A shallow color nonionic surfactant OXO synthesis fatty alcohol PEGS was synthesized by direct esterification, It is a high performance thickening agent, The optimal condition of the esterification reaction was introduled of compound catalyst, lower pressure of the reaction system, opening into nitrogen, and removing the oxygen. The rate of production reached high amount to 99, 5%, And the PEGS can act for the polyoxyethylene fatty alcohol ether （AEO） usage,prepare the surfactant and become efficiently textile auxiliaries according to the level of the demand＇s HLB.
