C60CCl4 phase diagram: polythermal behaviour of solvates C60, 12 CCl4 and C60, 2 CCl4

Polythermal investigation of the C60CCl4 system resulted in two phase diagrams. The stable one involves two solvates with 1:12 and 1:2 molar ratios, respectively. A metastable diagram, only showing the 1:2 solvate, has been observed. C60, 12 CCl4 and C60, 2 CCl4 decompose peritectically at 299 and 402 K, with ΔH = 15.2 and 61 J g−1, respectively. C60, 12 CCl4 is formed with a positive excess volume while C60, 2 CCl4 does so with a negative one. The desolvation enthalpy for C60, 2CCl4 and sublimation enthalpy for pure CCl4 are close.
