A series of novel, ultra-long-chain amidosulfobetaine surfactants were prepared by amidation of ultra-long-chain fatty acids directly with N,N-dimethyl-1,3-propanediamine in the absence of solvents, followed by quaternization of the intermediates with 1,3-propanesultone in ethyl acetate.
一系列新型超长链酰胺磺基甜菜碱表面活性剂是通过在无溶剂条件下直接将超长链脂肪酸与N,N-二甲基-1,3-丙二胺进行酰胺化反应制备的,随后用乙酸乙酯中的1,3-丙烷磺内酯对中间体进行季铵化处理。
