EFFECT OF AMYL ALCOHOL ON THE PHASE-BEHAVIOR OF CARBOXYMETHYLATED ETHOXYLATES OF ISONONYLPHENOL IN A SURFACTANT WATER HYDROCARBON SYSTEM

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.
