Phase diagrams of diphenyl ether–n-tetradecane and diphenyl–n-tetradecane systems

Abstract

Phase equilibria in diphenyl ether–n-tetradecane and diphenyl–n-tetradecane systems are investigated calorimetrically. The phase diagrams of these systems are calculated using the Schröder–Le Châtelier equation. Based on the calculated data, an experimental study of phase equilibria by means of differential scanning calorimetry is planned. The melting points, fusion enthalpies of the eutectics, and their compositions are determined. The liquidus curves of the systems are built using the experimental data.
