The paper presents some data on the temperature dependence of solubility of individual light fullerenes (C(60) and C(70)) and industrial fullerene mixtures (w(1) = 0.65 C(60) + w(2) = 0.34 C(70) + w(3) = 0.01 C(n) (n = 76 to 90)) in 1-chloronaphthalene and 1-bromonaphthalene in the temperature range from (10 to 60) degrees C. Solubility and density temperature dependences are presented and characterized; compositions of equilibrium solid phases are determined.
