Abstract:
The volume properties of water soluble tris-malonate of light fullerene – C$_{60}$ [= C(COOH)$_{2}$]$_{3}$ were investigated with the help of quartz pycnometers at 25$^\circ$C, including the concentration dependence of density, average molar volume of the solutions and partial molar volumes of C$_{60}$ [= C(COOH)$_{2}$]$_{3}$ and H$_{2}$O. Concentration dependence of the refraction index in water solutions of C$_{60}$ [= C(COOH)$_{2}$]$_{3}$ was also determined with the help of refractometer, specific and molar refraction of the components were calculated with the help of the rules of the additive refraction of solution components.
Keywords:tris-malonate of light fullerene, volume properties, refraction.
