This Article presents data on the solubility of fullerenes in binary C(60) + C(6)H(5)CH=CH(2) and C(70) + C(6)H(5)CH=CH(2) systems within the temperature range from (15 to 80) degrees C and the solubility of fullerenes along with their distribution between liquid and solid phases in the ternary C(60) + C(70) +C(6)H(5)CH=CH(2) system at temperatures of (-15, 0, and 25) degrees C. The solubility polytherms for the said binary systems and isotherms for the said ternary system are discussed; compositions of equilibrium solid phases are determined.
