ABSTRACT
The liquid-liquid equilibria of systems that involves lactic acid in the aqueous phase and tri-isooctylamine with diluents as dodecane and 1-dodecanol (active or/and inert) were measured experimentally at three temperatures (306.1, 310.1 and 316.1 K). A previous liquid-liquid equilibrium model that is based on Nernst's distribution law and mass action law equilibria was
