Аннотация:
Cryometry investigations of the C$_{60}$(OH)$_{24\pm2}$ - H$_{2}$O and C$_{70}$[=C(COOH)$_{2}$]$_{3}$ - H$_{2}$O binary systems were conducted over the 0.1 – 10 g concentration range of fullerenols per 1 dm$^{3}$ of solutions. The decreases of the temperatures at the onset of H$_{2}$O – ice crystallization were determined. Excess functions of aqueous solutions – water and fullerenols (trismalonates) activities and activity coefficients and excess Gibbs energy of the solutions were calculated. All solutions demonstrated huge deviations from those of ideal solutions. The last fact, to our opinion, is caused by a very specific – hierarchical type of association of fullerenols (trismalonates) solution components, which was proved by the results of visible light scattering analysis.
Ключевые слова:
