以N-(长链酰基)二乙醇胺二缩水甘油醚与长链脂肪醇反应，再与丙磺酸内酯反应，制备了具有三个长链烷基的双(磺酸)型两亲性化合物。 在相转移催化剂存在下，由相应的N-酰基二乙醇胺和环氧氯丙烷很容易获得二缩水甘油醚。 还根据类似的程序由N-乙酰基二乙醇胺制备了具有两个长链烷基的相同类型的化合物。 所有这些新型双链或三链表面活性剂均溶于水，并且比一般类型的具有一个磺酸盐基团的单链表面活性剂表现出更好的胶束形成和降低表面张力的能力。 三链化合物的临界胶束浓度（CMC）和γ-CMC值仍然远小于相应的具有两个共同烷基的双链化合物。 这些表面活性剂在水/空气界面（pC20）的吸附效率非常高。 测量它们的发泡性能、对毡片的润湿能力和石灰皂分散能力。
Bis(sulfonate) types of amphipathic compounds with three long-chain alkyl groups were prepared by the reaction of N-(long-chain acyl)diethanolamine diglycidyl ethers with long-chain fatty alcohols, followed by the reaction with propanesultone. The diglycidyl ethers were easily obtained from the corresponding N-acyldiethanolamines and epichlorohydrin in the presence of a phase-transfer catalyst. The same types of compounds with two long-chain alkyl groups were also prepared from N-acetyldiethanolamine according to similar procedures. All these new double- or triple-chain surfactants were soluble in water and showed much better micelle forming and ability to lower surface tension than general types of single-chain surfactants with one sulfonate group. The critical micelle concentration (CMC) and gamma-CMC values of the triple-chain compounds were still much smaller than those of the corresponding double-chain compounds with two common alkyl groups. The efficiency of adsorption at the water/air interface (pC20) of these surfactants was very high. Their foaming properties, wetting ability toward a felt chip, and lime-soap dispersing ability were measured.
