通过脂肪酸或脂肪胺与不饱和多元羧酸（富马酸、马来酸、衣康酸和乌头酸）的单加成反应，高产率地合成了含硫（S-）或亚氨基（N-）键的聚羧酸型绿色表面活性剂。它们具有表面活性剂性质和优异的生物降解性。此外，与具有N-键的相应表面活性剂相比，具有S-键的绿色表面活性剂显示出更好的钙离子螯合能力。在这些表面活性剂中，乌头酸衍生的具有S-键的聚羧酸盐表现出与3-氧代戊二酸二钠（ODA）（基于表面活性剂的摩尔的常规钙离子螯合剂）类似的钙离子螯合能力。
Polycarboxylate-type green surfactants with either sulfide- (S-) or imino- (N-) linkages were prepared in high yields by a single addition reaction of fatty mercaptan or fatty amine with unsaturated polycarboxylic acids such as fumaric, maleic, itaconic and aconitic acids. They exhibited surfactant properties and excellent biodegradabilities. Also, green surfactants with S-linkages showed better calcium ion sequestration abilities compared to the corresponding surfactant having an N-linkage. Among these surfactants, aconitic acid-derived polycarboxylate with an S-linkage exhibited calcium ion sequestration capacities similar to that of disodium 3-oxapentanedioate (ODA), a conventional calcium ion sequestrant on a molar basis of the surfactant.
