Heat of solution of extractants in hydrocarbon solvents

Abstract

Enthalpies of solution and dilution of tri- n-butylphosphate in n-dodecane, benzene and n-hexane and of tri- n-octyl- and tri- n-dodecylamine in benzene, and of the last also in chlorobenzene and n-octane have been determined by direct calorimetric measurements at 30°C. From known heats of vaporization of the extractants, the corresponding heats of solvation at infinite dilution have been derived.
