摘　　要：采用氢硅加成法,用不同含氢量的含氢硅油和聚醚制备得到了一系列具有梳状结构的非离子有机硅聚醚破乳剂(PESO).利用红外光谱对产物的结构进行了表征,采用表面张力、界面张力、粒度和破乳对PESO破乳剂进行性能检测.结果表明:随着含氢硅油(PHMS)含氢量的增加,PESO破乳剂的平均粒径增大且分布变宽,破乳性能减弱.当PHMS含氢量由1.6%降至0.18%时,CMC由0.808g/L降至0.646g/L,γCMC可降至22.03mN/m,脱水率高达85%.A series of non-ionic organosilicone surfactants with comb structure（PESO）was prepared through hydrosilylation method.Silicone polyether surfactant was synthesized by the addition reaction of silicone oil with different hydrogen contents and allyl polyether.The structure and solution property of PESO polymers were characterized via infrared spectroscopy,surface tension,interfacial tension,particle size and demulsification performance.The results showed that the average size of micelles increases with increasing the hydrogen content.However,the demulsification of PESO decreases.When the hydrogen content of PHMS decreases from 1.6%to 0.18%,the value of CMC decreases from 0.808g/L to 0.646g/L.The surface tension is low to 22.03mN/m.The dehydration rate is high to 85%.
