摘　　要：以异丙醇为溶剂、氯铂酸为催化剂,将烯丙基聚醚（F6）、丙烯酸十二酯与含氢硅油进行硅氢加成反应,合成了一种高分子表面活性剂,并将其与其它表面活性剂复配,制备出了一种原油破乳剂.通过红外光谱（FT-IR）、核磁共振氢谱（^1H-NMR）等对产物的结构进行了表征,通过表面张力和粒径测试对其性质进行了分析和研究,从而确定了最佳反应条件.在此条件下,活性氢转化率达到94.1%.通过不同的丙烯酸十二酯的量,确定了原油破乳效果的最佳条件.With isopropyl alcohol as solvent,chloroplatinic acid as catalyst,allyl polyether（F6）and acrylic twelve ester occur silicon hydrogen addition reaction with hydrogen containing silicone oil,synthesis a kind of polymer surfactant,and use it with other surface active compound,a crude oil demulsifier was synthesized.The structure was characterization via infrared spectroscopy（FT-IR）,nuclear magnetic resonance spectroscopy（^1H-NMR）,through the test of surface tension and particle size,the different ratio of polyether（F6）and hydrogen containing silicone oil and the different amount of acrylic twelve ester are analyzed and studied,ensure the best of reaction conditions.Under the condition,conversion rate of the active hydrogen can reach for 94.1%.Through the different amount of acrylic twelve ester,determine the best conditions of crude oil demulsification.
