| Popis: | In an effort to improve understanding of dissolution behaviour of fullerenes and their simple chemical derivatives the binary systems of C60, C70 and the piperazine monoadduct of [60] fullerene C60 N2C4H8 with a series of aromatic solvents have been studied by means of DSC. In certain systems solid solvates have been found to be the thermodynamically stable phases relative to saturated solution at room temperature. Identified solid solvates were characterized by their compositions, temperatures and enthalpies of incongruent melting transitions. The regularities in thermodynamic stability of the solvated crystals have been discussed along with dissolution properties of fullerenes and the derivative. Certain correlations have been observed. |
