摘要
壬基酚聚氧乙烯 (10)醚与氯磺酸反应生成新型表面活性剂NPSS ,较佳合成条件为 :醚酸投料摩尔比为1:0.9 ,硫酸化温度30～35℃ ,老化时间1.5h ,中和温度40～50℃。对NPSS的稠油乳化降粘特性进行了评价 ,单剂降粘率>80 %,复配后降粘效果更佳。
A new surfactant Sodium sulfate of nonylphenol polyoxyethylene(10)ether(NPSS)was synthesized from NPE-10 with chlorosulfonic acid.The optimum reaction conditions were chlorosulfonic acid/NPE-10=0.9:1(mol),sulfating temperature 30～35℃,aging time 1.5h,neutralizating temperature40～50℃,viscosity reducing property of NPSS for emulsifying heavy crude oils was measured and discussed.
