Mutual Solubilities of Terpene in Methanol and Water and Their Multicomponent Liquid−Liquid Equilibria

Abstract

Multicomponent liquid−liquid equilibria measured at T = 298.15 K have been reported for the ternary (water + methanol + α-pinene or + β-pinene or + limonene) and (water or methanol + α-pinene + limonene) systems and the quaternary (water + methanol + α-pinene + limonene) systems. The mutual solubilities of terpenes (α-pinene, β-pinene, and limonene) in methanol and water have been measured at T = 298.15 K. The experimental multicomponent liquid−liquid equilibrium data have been satisfactorily represented by using the extended UNIQUAC and modified UNIQUAC models.
