Abstract

A thermodynamic assessment was made of the (plastic-crystalline solid+ liquid) phase diagram in the system carbon tetrabromide + hexachloroethane. The phase diagram is an example of crossed isodimorphism: two(plastic-crystalline solid + liquid) loops crossing each other give rise to a three-phase equilibrium (in this case eutectic), The information used consisted of experimental liquidus data, the thermodynamic melting properties of the pure components and the enthalpy of fusion data of the mixed plastic-crystalline solid state with the hexachloroethane structure, The eutectic is an organic analog for the investigation of eutectic growth in metallic systems, The eutectic temperature is 357.55 K and the calculated eutectic mole fractions are 0.094 (solid), 0.118 (liquid) and 0.187 (solid). The values of the initial distribution coefficients are (i) at the carbon tetrabromide side: k(0)(0) = 0.79+/- 0.06; (ii) at the hexachloroethane side: k(0)(0) = 0.58.
