Abstract

The solubility in a ternary fullerenol-d (C60(OH)22–24)–SmCl3–H2O system at 25°C is studied via isothermal saturation in ampules. The solubility diagram is shown to be a simple eutonic one that consists of two branches corresponding to the crystallization of fullerenol-d (C60(OH)22–24 · 30H2O) and samarium(III) chloride SmCl3 · 6H2O crystallohydrates and contains one nonvariant eutonic point corresponding to saturation with both crystallohydrates. The long branch of C60(OH)22–24 · 30H2O crystallization shows the effect of fullerenol-d salting out of saturated solutions; in contrast, the short branch of SmCl3 · 6H2O crystallization shows the pronounced salting-in effect of samarium(III) chloride.
