Title: Effect of amyl alcohol on the phase behavior of carboxymethylated ethoxylates of isononylphenol in a surfactant-water-hydrocarbon system

Abstract

According to its behavior in a surfactant-water-hydrocarbon system containing electrolytes, the molecular and component composition of a surfactant with the products of carboxymethylation of ethoxylates of isononylphenol has been optimized for the Windsor microemulsion state III. For the condition of the occurrence of an ultra-low interphase tension at a water-octane interface, a mathematical description is presented of the optimum volume of amyl alcohol in the system, in the form of a linear dependence on the degree of oxyethylation of the alkylphenol and the degree of carboxymethylation of the ethoxylates. An estimate is made of the contribution of the carboxymethyl and ethoxyl groups to the increase of the hydrophilic-lipophilic balance of the surfactant.
