Abstract

Some cleavable dianionic surfactants were prepared by the reaction of aldehydes with diethylbis(hydroxymethyl)-malonate, followed by saponification with sodium hydroxide. The critical micelle concentrations of the surfactants were determined.

Key words  Aldehydes - cleavable dianionic surfactants - critical micelle concentration - diethylbis(hydroxymethyl) malonate - 1,3-dioxane ring
