Synthesis and properties of alkyl glyceryl ether sulfonate

Abstract

Abstract In this work, alkyl glyceryl ether sulfonates with two alkyl chain lengths were synthesised by etherification and sulfonation. The structures of these sulfonates were characterised by FTIR, 1H NMR and MS. Their characterisations were investigated for their surface properties and thermodynamic properties by surface tension, conductivity and fluorescence methods. The critical micelle concentration (CMC) of surfactants increases with increasing temperature and decreases with increasing alkyl chain length. The micellation process of alkyl glyceryl ether sulfonates is spontaneous and driven by entropy.
