On the basis of the isothermal saturated method in ampules, the solubility of bromoderivatives C60Brn = 6, 8, 24) in 1-chloronaphthalene and 1-bromonaphthalene in the (10 to 60) degrees C temperature range was determined. The temperature dependencies of solubility and density are presented and characterized, and the compositions of equilibrium solid phases are determined.
