Deuterium isotope effects in liquid-liquid phase diagrams : methanol + n-hexane systems

Abstract

Liquid-liquid phase diagrams have been measured for the systems CH₃OH+n-C₆H₁₄, CH₃OH + n-C₆D₁₄, CH₃OD + n-C₆H_I4 and CH₃OD + n-C₆D₁₄. The upper critical solution temperatures of these systems are 306.70, 304.30, 307.59 and 304.84 K, respectively. The results are in accord with the qualitative predictions of the Rabinovich theory, which considers hydrogen bond and London dispersion interactions.
