摘要：

Thermodynamic properties of binary systems of C-60 With 1,2- and 1,3-dibromobenzenes have been studied by means of differential scanning calorimetry (DSC). Solid solvates with the compositions C(60)3(1,2-C6HSBr2); C(60)2(1,3-C6H4Br2) and C(60)0.6(1,3-C6H4Br2) have been found. The solvates have been characterised by their enthalpies and temperatures of incongruent melting transition and in part by X-ray powder data. It has been shown that positional isomers 1,2- and 1,3- of the substituted benzenes formed two series of "typical' phase diagrams. Solubility behaviour of C-60 in positional isomers has been discussed. (C) 2001 Elsevier Science B.V. All rights reserved.
