Volume Properties and Refraction of Aqueous Solutions of Bisadducts of Light Fullerene C-60 and Essential Amino Acids Lysine, Threonine, and Oxyproline (C-60(C6H13N2O2)(2), C-60(C4H8NO3)(2), and C-60(C5H9NO2)(2)) at 25 degrees C

摘要

Concentration dependences of the density of aqueous solutions of bisadducts of light fullerene C-60 and essential amino acids are studied by pycnometry. Concentration dependences of the average molar volumes and partial volumes of components (H2O and corresponding bisadducts) are calculated for C-60(C6H13N2O2)(2)-H2O, C-60(C4H8NO3)(2)-H2O, and C-60(C5H9NO2)(2)-H2O binary systems at 25 degrees C. Concentration dependences of the indices of refraction of C-60(C6H13N2O2)(2)-H2O, C-60(C4H8NO3)(2)-H2O, and C-60(C5H9NO2)(2)-H2O binary systems are determined at 25 degrees C. The concentration dependences of specific refraction and molar refraction of bisadducts and aqueous solutions of them are calculated.
