【摘要】 实验室考察了非离子表面活性剂ＯＲＳ对石油氧化皂（ＰＯＳ２）及其复配体系界面活性的影响。结果发现，在ＰＯＳ２与ＰＯＳ２／ＯＲＳ复配体系中加入ＯＰ类（ＯＰ７，ＯＰ１０，ＯＰ３０）和Ｔｗｅｅｎ类（Ｔｗｅｅｎ２０，Ｔｗｅｅｎ８０）非离子表面活性剂，不能改善体系的界面活性，反而使体系的界面活性变差。更多还原

【Abstract】 Effects of surface activity of nonionic surfactants on petroleum oxidation soap(POS 2) and its combined system are studied experimentally Adding nonionic surfactants series OP,OP 7,OP 10,OP 30,and Tween series,Tween 20,Tween 80, into POS/alkaline system and POS/ORS/alkaline combined system,their surface activity cannot be improved but become worse The experiment done shows that nonionic surfactants may decrease the surface activity of POS 2 and its combined system更多还原
