Title: Aqueous phase microemulsions employing alkyl glucamide surfactants with chlorinated hydrocarbons

Abstract

This paper summarizes experiments on nonionic surfactants for electrolyte-free aquifer remediation of chlorocarbon contaminants. Various combinations of linear and branched alkylglucamides succeeded in producing Winsor Type I and III microemulsions at room temperature with various chlorinated hydrocarbons with little or no added electrolyte. Solubilization parameters at 0 and 0.1% NaCl were determined for the surfactant solutions. In comparing these two values, the solubilization parameter shows no definite trend of increasing as had been previously noted. There is no apparent explanation for this anomaly, except that operating at 0% NaCl may not be governed by the same rules that apply to systems with an electrolyte. A class of nonionic surfactants that produce aqueous phase microemulsions with no electrolyte and Winsor III middle phase microemulsions was identified.
