ANIONIC MULTICHAIN TYPE SURFACTANTS AND A METHOD OF PREPARING THE SAME

摘要

PURPOSE: An anionic multi-chain type surfactant is provided to ensure remarkably low critical micelle concentration compared to a conventional anionic surfactant and excellent surfactant activation effect in a low concentration. CONSTITUTION: An anionic multi-chain type surfactant has a structure represented by chemical formula 1. A method for preparing the anionic multi-chain type surfactant comprises a step of preparing a disulfonate compound of chemical formula 1 by reacting a diol compound of chemical formula 2 and 1,3-propane sultone in the presence of a basic catalyst. In the chemical formula 1 and 2, R^1 and R^2 are independently selected from C1~C30 linear or branched alkyl and M is selected from the alkali metal.
