EFFECT OF HYDROPHOBICITY ON DISTRIBUTION AND INTERRACIAL ADSORPTION EQUILIBRIA OF N-8-QUINOLYLSULFONAMIDE

Abstract

Using five kinds of alkylbenzene-substituted N-8-quinolylsulfonamide having different alkyl-chain lengths, the effect of hydrophobicity on distribution and interfacial adsorption equilibria was examined.
It was found that the equilibrium constants of distribution and interfacial adsorption of the extractants between organic and aqueous solutions were remarkably affected by the hydrophobicity of the extractant, but the acid dissociation constant and the interfacial area occupied by unit mole of the extractant were not affected.
