Abstract:
Diagrams of phase equilibrium liquid–vapor, solid–liquid (solubility diagram) and liquid–liquid (delamination diagram) at 25$^\circ$C in the ternary system, consists of water soluble fullerene derivative and rare earth metal salt C$_{60}$(OH)$_{24}$–NdCl$_3$–H$_2$O were investigated. The existence of miscibility gap in liquid solutions, saturated by fullerenol-24 (C$_{60}$(OH)$_{24}$) is proved.
