摘　　要：以苯乙烯、甲基丙烯酸丁酯、丙烯酰胺和甲基丙烯酰氧乙基三甲基氯化铵为合成单体,利用氧化还原引发剂过硫酸铵/亚硫酸氢钠并通过乳液聚合法合成了O/W稠油破乳剂,并用红外光谱和核磁共振氢谱对其结构进行了表征。研究了反应温度、反应时间、乳化剂用量和单体质量分数对产率的影响。通过正交实验确定出最佳反应条件。破乳性能测试表明,在最佳条件下合成的O/W破乳剂的脱水率达到85.2%,水中含油量为53 mg/L,破乳性能优于工业上用的OX-932破乳剂,该O/W破乳剂对胜利油田孤东稠油具有良好的破乳效果。Rcdox initiator ammonium persulfate/sodium bisulfite is used to synthesize non-polyether O/W heavy demulsifier by emulsion polymerization, using styrene, butyl methacrylate, acrylamide and methacryloyloxyethyl trimethyl ammonium chloride as monomers. The structure is characterized by infrared spectroscopy and nuclear magnetic resonance spectroscopy. The factors affecting the conversion including reaction temperature, emulsifier dosage, initiator dosage and monomer concentration, are studied. By using orthogonal experiment, the optimal reaction conditions are determined as follows ：65℃ of reaction temperature, 1.6% （the total quality system） of emulsifier dosage, 1.0 % （the total mass of the monomers） of initiator dosage and 30% of monomer concentration. Performance tests show that under the appropriate condition of demulsification,the dehydration rate of O/W demulsifier is 85.2% and the oil content in water is 53 mg/L. The O/W demulsifier exhibits superior performance to that of industrial demnlsifier OX-932. Moreover, this O/W demulsifier has good demulsification effect for Gudong heavy oil in Shengli oilfield.
