【摘要】 考察了松香酸聚氧乙烯酯磺基琥珀酸单酯二钠盐的合成工艺条件,并测定了合成产物的表面化学性能。较佳的合成工艺条件为:松香酸聚氧乙烯酯与顺酐摩尔比为1:1.05,酯化温度95℃,酯化时间3.0 h;顺酐与亚硫酸钠摩尔比为1:1,磺化温度80℃,磺化时间3.5 h。性能测试和应用结果表明,该产物具有良好的乳化力和分散力,对大庆黑帝庙稠油具有较好的乳化降粘效果。更多还原

【Abstract】 The synthetic conditions and surface properties of disodium sulfosuccinate monoester of polyoxylethylene abietate(DSMPA) were investigated in the paper. The optimal process conditions for esterification were as follows: the molar ratio of polyoxylethylene to maleic anhydride 1:1.05, temperature 95 ℃, time 3.0 h.for sulfonation, the molar ratio of maleic anhydride to sodium sulfite 1:1, temperature 80 t, time 3 .5 h. The property tests and application results showed that DSMPA had excellent dispersibility, emulsifying ability and high viscosity reducing efficiency for emulsifying Daqing Heidimiao heavy crude oils.更多还原
