Extraction equilibria of the liquid(I)-liquid(II) type have been studied for the first time in a system containing light fullerenes C[sub 60] and C[sub 70]. The experiments were performed with a five-component mixture of fullerene C[sub 60], fullerene C[sub 70], o-xylene, i-butylamine, and water at 25°C. Isothermal diagrams describing the distribution of fullerene components between separating liquid phases have been obtained. The distribution coefficients of fullerenes (C[sub 60] and C[sub 70] concentrations in the xylene phase relative to those in the amine phase) are found to be almost constant and approximately equal to ∼16.1 for both C[sub 60] and C[sub 70].
