The extraction of sulphuric acid with Di- and Tri-(3,5,5-trimethylhexyl)amines

Abstract

Equilibrium constants have been obtained for the distribution of sulphuric acid between aqueous solutions and isoamyl alcohol solutions of di- and tri-(3,5,5-trimethylhexyl)amines forming the normal amine sulphates and the amine bisulphates. The extraction follows a simple equilibrium law using a solvent for the amines (isoamyl alcohol) in which it has also been shown that no aggregation phenomenon of the amine salts occurs.
