| 摘 要： | 以醇胺硅油(PAPS)和马来酸酐(MA)为原料,在对甲苯磺酸(PTSA)的催化作用下,通过开环反应合成了一种新型有机硅琥珀酸酯(PMPS)表面活性剂。通过单因素实验优化出PMPS合成条件:原料n(MA)∶n(PAPS)=1.00∶0.31,反应温度90℃,w(PTSA)=0.6%(以PAPS质量计),反应时间4.5 h。通过综合热分析测试了PMPS的热分解温度Tg为192.8℃,测定了PMPS的临界胶束浓度CMC为0.12 g/L。

| Abstract: | An anionic silicone surfactant(PMPS) is synthesized by ring-opening reaction using polyether and alcohol amine modified polysilosane(PAPS) with maleic anhydride as the raw materials,and p-toluenesulfonic acid is used as the catalyst.The appropriate reaction conditions are optimized by the single factor experiment for the PMPS:the reaction molar ratio of n(MA)∶n(PAPS)=1.00∶0.31,the reaction temperature of 90℃,the amount of catalyst of 0.6 wt%(the percentage of PAPS quality),and the reaction time of 4.5 hours.The molecular structure of the raw materials and PMPS are characterized and analyzed by FTIR,13C-NMR and 1H-NMR;the thermal properties of PMPS is characterized and analyzed by TGA,the thermal decomposition temperature is 192.8℃,and the critical micelle is 0.12 g/L. |
