以环氧氯丙烷、季戊四醇、长链醇、1,3-丙磺酸内酯和氢氧化钠为原料，通过酯化反应、开环反应和磺化反应制备了四聚磺酸盐表面活性剂1,1,1,1-四-(2-氧基丙基磺酸盐-3-烷基醚-丙氧基)新戊烷。通过FTIR、1H-NMR和元素分析确认了所制备化合物的化学结构。随着碳链长度的增加，其CMC值最初下降。烷基链越长，熔点越高。所有这些四聚磺酸盐表面活性剂的克拉夫特点均低于0℃，并且它们具有优异的水溶性。这些化合物的表面活性性能优于一般磺酸盐表面活性剂SDS。这些表面活性剂在水/空气界面（pC20）的吸附效率非常高。研究了它们的发泡性能、毡片润湿能力以及石灰皂分散能力。
Tetrameric sulfonate surfactants 1,1,1,1‐tetra‐(2‐oxypropyl sulfonate‐3‐alkylether‐propoxy)neopentanes were prepared with raw materials containing epichlorohydrin, pentaerythritol, long‐chain alcohols, 1,3‐propane sultone and sodium hydroxide by esterification, a ring opening reaction, and a sulfonation reaction. The chemical structures of the prepared compounds were confirmed by FTIR, 1H‐NMR and element analysis. With the increasing length of the carbon chain, the values of their CMC initially decreased. The longer the alkyl chain, the higher the melting point. The Krafft point of all these tetrameric sulfonate surfactants was below 0 °C and they had excellent water solubility. These compounds were superior in surface active properties to general sulfonate surfactants SDS. The efficiency of adsorption at the water/air interface (pC20) of these surfactants was very high. Their foaming properties, their wetting ability of a felt chip, and their lime‐soap dispersing ability was investigated.
