N2 - Using a Beckman thermometer, the concentration dependence of water crystallization temperatures was investigated for C60(OH)22–24 – H2O, C70(OH)12 – H2O, C70[C(COOH)2]3 – H2O, С60(C5H9NO3)2 - H2O, С60(C6H14N2O2)2 – H2O binary systems. The semi-empirical Virial Decomposition Asymmetric Model of virial expansion of the excess Gibbs energy of the light fullerene derivatives solutions was applied. On the basis of the proposed model, partial and average molar thermodynamic functions of binary solutions as well as the conditions of stability against phase separation were determined.
