摘　　要：以甲基封端聚醚、自制低含氢硅油和丙烯酸壬基酚聚氧乙烯聚氧丙烯酯为原料,在氯铂酸的催化下合成了一种聚硅氧烷稠油破乳剂。通过红外光谱和核磁共振氢谱对其进行了表征。考察了反应温度、反应时间、物料比和催化剂用量对反应转化率的影响,最佳工艺条件为:反应温度95℃,反应时间7 h,n(Si—H)∶n(CC)=1.0∶1.2,催化剂用量占总反应物的质量分数为40μg/g,反应转化率达到92.86%。性能测试表明,在最佳条件下合成的破乳剂对稠油具有较好的破乳效果。Under the catalysis of chloroplatinic acid,a polysiloxane heavy oil demulsifier,was synthesized taking methyl terminated polyether,the self-made low hydrogen silicone oil and acrylic nonylphenol polyoxyethylene polyoxypropylene ester as raw materials.The chemical structure were characterized by IR spectroscopy and nuclear magnetic resonance （1HNMR） spectrum.On basis of the single factor test the effects of different factors on the conversion rate of reation,to determine the optimum technological conditions as follows：the reaction temperature was 95 ℃,the reaction time was 7 h,the molar ratio of silicon-hydrogen bonds was 1.0：1.2,the amount of catalyst was 40 μg/g.Under this condition,the conversion rate of reation reached 92.86%.The performance tests show that the synthesized crude oil demulsifier with the optimal conditions exerted better effects.
