Preparation and Characterization of Alkylethoxyethanesulfonate in Superbasic System KOH-DMSO

Abstract:

Alkylethoxyethanesulfonate is one kind of nonionic-anionic surfactant with a polyglycol ether chain and a sulfonic group at the end of the chain. It was synthesized in a new method by using fatty alcohol-polyoxyethylene ether MOA-3, thionyl chloride and sodium isethionate as raw materials, and then the intermediate chloridepolyglycol ether MOACl-3 reacted with sodium isethionate in a superbasic system KOH-DMSO.The structures of MOA-3,MOACl-3 and alkylethoxyethanesulfonate MOASO-3 were confirmed by their IR spectrums, and the saltresistance of MOASO-3 was studied. IR analysis results indicate the intermediate and product all have the same structure with the aim compound. The saltresistance results show that MOASO-3 is compatible with NaCl aqueous solutions, when the concentration of MOASO-3 is 0.2wt%, the surfactant-water solutions were clear and transparent up 0.6wt% NaCl.
