The Gemini cationic surfactant 1?3-dis(n-octadecyldimethylammonium chloride)-isopropanol was prepared using n-octadecyldimethylamine (OTA) and epichlorohydrin (EPIC) through the middle product n-octadecylglycidyldimethylammonium chloride (OGDMAC).

• 以十八烷基二甲基胺(OTA)和环氧氯丙烷(EPIC)为反应原料,经过环氧中间体十八烷基失水甘油基二甲基氯化铵(OGDMAC)合成了Gemini阳离子表面活性剂1,3二(十八烷基二甲基氯化铵)异丙醇。
