摘 要:以丙烯酸(AA),甲基丙烯酸(MAA),丙烯酸丁酯(BuAc),甲基丙烯酸甲酯(MMA)为单体,过硫酸钾(KPS)为引发剂,十二烷基硫酸钠(SDS)为乳化剂,三乙醇胺与无水亚硫酸钠分别为链转移剂与终止剂,水为分散介质,采用乳液法合成了一种水溶性四元共聚物破乳剂。考察了水用量、乳化剂用量、引发剂用量、加料速率、聚合温度、单体配比、链转移剂与终止剂用量等反应条件对产物破乳性能的影响,并且对原油破乳条件进行了讨论,对产物进行了红外检测分析。结果表明:在水用量60g、乳化剂用量1.6g、引发剂用量0.25g、加料时间130 min、聚合温度80~85℃、链转移剂与终止剂分别为0.1g与0.15 g、单体总量20 g、m(AA):m(MAA):m(BuAc):m(MMA)=0.75:0.25:12:2条件下,所得产物的原油破乳脱水率最佳。当加药量300 mg/L时,原油脱水率达97.01%。A kind of water soluble demulsifier of quaternary-copolymerization was synthesized by latex method with acrylic acid (AA), methyl acrylic acid (MAA), butyl acrylate (BuAc) and methyl acrylate (MMA) as raw materials, potassium persulfate (KPS) as initiator, sodium lauryl sulfate (SDS) as emulsifier, triethanolamine as chain transfer agent, anhydrous sodium sulfite as chain terminator, and water as dispersion medium. The optimum conditions were obtained as follows: 60 g water, 1.6 g emulsifier, 0.25 g initiator, adding time 130 min, polymerization temperature 80 -85 ℃, 20 g monomers, 0. 1 g chain transfer agent and 0. 15 g chain terminator when the monomer m (AA) : m (MAA) : m(BuAc) : m(MMA) was 0.75 : 0.25 : 12 : 2. When the dosage of the demulsifier was 300 mg/L, the dehydration rate of the crude oil reached up to 97.01%.
