About this Chemistry article
Solubility of fullerene (C60) in a variety of solvents by R. S. Ruoff; Doris S. Tse; Ripudaman Malhotra; Donald C. Lorents is a Chemistry article available to read on EtoBox.
The room temperature solubility of pure c 6 0 has been determined in 47 solvents. The solubilities cover a wide range, from 0.01 mg/mL in methanol to 50 mg/mbin 1-chloronaphthalene. The solubilities in CS2, toluene, and hexane, three of the commonly employed solvents, are 7.9,2.8, and 0.04 mg/mL, respectively. An examination of the solubilities of c 6 0 as a function of the solvent properties such as index of refraction, dielectric constant, molecular size, Hildebrand solubility parameter, and H-bonding strength reaffirms the century-old principle 'like dissolves like". No single solvent parameter can uniformly predict the solubility of C ~O , but a composite picture of solvents with high solubility for C ~O emerges: large index of refraction, dielectric constant around 4, large molecular volume, Hildebrand solubility parameter equal to 10 and tendency to act as a moderate strength nucleophile. ## Experimental Section Pure Cm was obtained by using column chromatography with neutral alumina to purify 'extract" obtained from primary arc-
