研究了非离子活性剂OP-10的磷酸酯盐化与羧甲基化,用正交试验设计法找到了由OP-10合成高浊点、低表面张力、低临界胶束浓度和有一定润湿反转能力及耐温、耐盐能力的非离子-阴离子型活性剂的最佳条件。用此最佳条件对其他含聚氧乙烯基的非离子活性剂(如聚氧乙烯十八醇醚-4、2070、吐温80)改性也取得好的结果。 The phosphate esterification and carboxymethylation of non-ionic surfactant OP-10 were studied. The optimum conditions for the synthesis of OP-10 with high cloud point, low surface tension, low critical micelle concentration, Wet reversal ability and temperature, salt tolerance of the best non-ionic - anionic active agent. Good results have also been obtained with the modification of other polyoxyethylene-containing nonionic surfactants (such as polyoxyethylene octadecyl ether-4, 2070, Tween 80) using this optimum.
