摘　　要：以壬基酚、二溴烷烃和氯磺酸为原料,合成了2种双壬基二苯双醚磺酸盐型双子表面活性剂。在中间体的合成反应中引入超声波,通过正交试验优化了生成双醚中间体的反应条件,并考察了超声波功率对产率的影响。通过红外光谱、质谱以及核磁共振对产物结构进行了表征。研究了产物的表面活性、乳化性能和泡沫性能。将合成的Gemini A和Span 80复配作为复合乳化剂来乳化甲基硅油。结果表明,生成双醚的适宜反应条件为:n(壬基酚)∶n(二溴烷烃)=2.02∶1,碱用量为20%(质量分数),65℃下反应1.5 h,超声波功率为250 W。合成的双子表面活性剂具有良好的表面活性、乳化性能和泡沫性能。采用复合乳化剂得到了均匀稳定的甲基硅油乳液。Two kinds of bis - （nonylphenyl alkyl ether） sulfonate Gemini surfactant were synthesized with nonyl phenol, dibromo alkanes and chloro sulfonic acid as main starting materials. Ultrasonic wave was applied to the synthesis of the intermediates. Reaction conditions of the his - ether intermediates were optimized by orthogonal designed experiments, and the effect of ultrasonic power on the yield was investigated. Structures of the products were characterized by FTIR, HPLC/MS and ＇HNMR. The surface activity, emulsifying performance and foam performance of the products were studied. Methyl silicone oil was emulsified by a blend emulsifier of the product Gemini A and Span 80. Results showed that the suitable reaction conditions for synthesis of the intermediates are ： n （ nonyl phenol） ： n （ dibromo alkanes ） = 2.02 ： 1 ; alkali dosage, 20% （ mass fraction ） ; reaction temperature ,65 ℃ for 1.5 h and with ultrasonic power of 250 W. Gemini surfactants display a higher surface activity and better emulsification and foam performance. Stable silicone oil emulsion is obtained with blend emulsifier containing the Gemini surfactant.
