The system carbon-tetrachloride plus neopentane: A complete thermodynamic analysis

An experimental reinterpretation together with a thermodynamic analysis of the two-component system (CCl4) + (C(CH3)(4)) has been performed. The 35-ye ar-old specific heat diagrams obtained by adiabatic calorimetry have been r evised in order to remove the inconsistencies of the tentative experimental phase diagram. The fact that the two components of the system do not have the same ODIC form was ignored 30 years ago and, at present, it has been co nsidered. From a thermodynamic point of view the two-component system is a very nice example of crossed isodimorphism: two ODIC + liquid loops crossin g each other give rise to a three-phase equilibrium. The thermodynamic info rmation of the excess magnitudes is wide enough to perform a complete and r ealistic thermodynamic analysis. Likewise, the excess thermodynamic magnitu des in the ODIC states have been well explained by means of the quasi-subre gular solution model including a compensation law. (C) 2000 Academic Press.
