Purity determination by calorimetry. An analysis of relationships describing solid-liquid equilibria in eutectic systems

Transitiometry: PVT – Scanning Calorimetry for the Simultaneous Determination of Thermal and Mechanical Properties

“…The different temperatures for these maxima are plotted vs. the gas-free mole fraction in Fig. 13 atmospheric pressure: n this work, h [15], 10 MPa CO 2 pressure: r this work, naphthalene/benzoic acid at atmospheric pressure, 10 MPa carbon dioxide pressure and 20 MPa helium pressure is obtained in this way. For the eutectic mixture at atmospheric pressure an experimental value was published by Vallebona [15].…”
