摘　　要：以蓖麻油酸、聚乙二醇(PEG-600)、马来酸酐为原料,合成了一种Gemini非离子表面活性剂(MARAPEG-15),并与单链表面活性剂蓖麻油酸聚乙二醇单酯进行了性能对比。结果表明:MARAPEG-15的表面张力及临界胶束浓度较低,乳化性和润湿性均较好,可作为水包油型乳化剂。A novel nonionic Gemini surfactant （MARAPEG-15） was synthesized by using ricinoleic acid （RA）, polyethylene glycol（600） and maleic anhydride as main materials. Its surface properties were tested, and compared with that of Castor oleic acid polyethylene glycol monoester （RAPEG-15）. Results show that MARAPEG-15 has lower surface tension and critical micelle concentration, better emulsifying and wetting properties, so it can be used as an oil-in-water emulsifier.
