The solubility of fullerenes in n-alkanols-1

The isothermal and polythermal solubility of C60 and fullerene mixture (60% C60, 39% C70, and 1% C76–90) in unbranched saturated alcohols C1–C11 was studied over the temperature range 20–80°C. The isotherms and polytherms of solubility are presented and characterized.

Extraction equilibria in the fullerene-containing system C60-C70-1,2,4-trichlorobenzene-ethanol-H2O

The liquid (I)-liquid (II) extraction equilibria in the five-component system fullerene C60-fullerene C70-1,2,4-C6H3Cl3-C2H5OH-H2O were studied at 25°C. Isothermal diagrams of distribution of the fullerene components among stratifying liquid phases at a constant content of H2O were obtained.

Temperature Dependence of the Light Fullerenes Solubility in Natural Oils and Animal Fats

Polythermal solubility of individual light fullerenes (C60, C70) and industrial fullerene mixture (60% C60, 39% C70, 1% C76–90) in natural oils (unrefined and refined sunflower‐seed oil, corn oil, olive oil, linseed‐oil, apricot‐kernel oil, grape‐seed oil, pignolia oil, walnut oil) and animal fats (pork fat, chicken fat, beef fat, margarine, lamb fat, desi) is investigated; temperature dependences of solubility are presented and characterized; composition of solid solvates is determined.

Caprolons modified with fullerenes and fulleroid materials

Conditions for the preparation of modified Caprolons were determined and optimized. A number of laboratory and industrial samples was prepared. Their main mechanical, physicochemical, and electrical properties were determined.

The isothermal (20°C) solubility of fullerene C70 in solvents of the homologous series of nonbranched saturated alcohols C1-C11 and polythermal (20–80°C) solubility of fullerene C70 in solvents of the homologous series of nonbranched saturated alcohols C4-C11 were studied. The corresponding solubility diagrams are presented and characterized.

Solubility of fullerenes in n-alkanoic acids C2–C9

The solubility of fullerene C60 and a fullerene mixture [C60 (75%), C70 (24%), C76–80 (1%)] in linear alkanoic acids (C2–C9) was determined at 20°C. The solubilities of C60 and a fullerene mixture in carboxylic acids were examined in relation to the number of carbon atoms in the carboxylic acid.
