Abstract

Concentration dependences of the density of aqueous solutions of bisadducts of light fullerene С60 and essential amino acids are studied by pycnometry. Concentration dependences of the average molar volumes and partial volumes of components (Н2О and corresponding bisadducts) are calculated for С60(C6H13N2O2)2–Н2О, С60(C4H8NO3)2–Н2О, and С60(C5H9NO2)2–Н2О binary systems at 25°C. Concentration dependences of the indices of refraction of С60(C6H13N2O2)2–Н2О, С60(C4H8NO3)2–Н2О, and С60(C5H9NO2)2–Н2О binary systems are determined at 25°C. The concentration dependences of specific refraction and molar refraction of bisadducts and aqueous solutions of them are calculated.
