烯基琥珀酸酐改性硅油的合成及表面性能

Study on Synthesis and Surface Performance of Alkenyl Succinic Anhydride Modified Silicone

摘要:

以含氢硅油、烯基琥珀酸酐为原料，在氯铂酸螯合物的催化作用下，通过硅氢加成反应合成了烯基琥珀酸酐改性硅油，再用醇醚对烯基琥珀酸酐改性硅油进行酯化。通过单因素实验考察了反应时间、反应温度、以及物料摩尔比对烯基琥珀酸酐酯化程度的影响，并得出较适宜的反应条件为：反应温度为150℃，反应时间为17 h，n(酸酐) : n(醇醚)=1 : 2.6，在该条件下，产品的转化率达98.22%。并对合成产品的表面性能进行了测试。

Abstract:

With using silicone oil containing hydrogen and alkenyl succinic anhydride as raw materials and chloroplatinic acid as the catalyst,alkenyl succinic anhydride modified silicone was synthesized through the silicon hydrogen addition reaction.Then alkenyl succinic anhydride modified silicone was estedfied by alcohol ether.The influence of reaction temperature,reaction time and material mole ratio on degree of esterification were investigated by single factor experiment.And the appropriate reaction conditions as follows:the reaction temperature is 150℃,the reaction time is 17 h, the ratio of reactants [n (anhydride): n (alcohol ether)] is 1 : 2.6. Under these conditions, the conversion of product is 98.22%.And test the surface performance of the product.
