Solubility of light fullerenes in vegetable oils

Fullerenol Synthesis and Identification. Properties of the Fullerenol Water Solutions

“…In particular, no absorption peaks typical for the light fullerenes and their derivatives in aromatic and nonaromatic solvents were observed near 472 nm (for the fullerene C 70 ), near 335 nm (for both fullerenes C 60 and C 70 ) and (320 to 330) nm (for bromine-fullerenes C 60 Br n (n ) 6, 8, 24). 1,[11][12][13][14]23,24 As a whole, the UV spectra of the fullerenol solutions turned out to be not informative enough but can be used for the composition determination. For example, the determination of the fullerenol composition is possible in aqueous environments if the wavelengths λ ) (300 to 500) nm, where the absorption is not too high.…”

Fullerenes

“…13 Polythermal solubility of individual light fullerenes C 60 and C 70 and industrial fullerene mixture, in natural oils and animal fats in the temperature range from 0-80 1C was studied; temperature dependences of solubility were presented and characterised and the composition of solid solvates was determined. 14,15 It has been found that C 60 molecules can be solublised in polar solvents, such as CH 3 CN and acetone, at room temperature in the presence of a solubilising agent such as syndiotactic poly(methyl methacrylate). This is due to the encapsulation of C 60 in the helical solubilising agent cavity.…”

Solubility of Light Fullerenes in Organic Solvents

“…Solubility of individual light fullerenes over a temperature range has been investigated for a still narrower number of solvents. Thus, in the case of the C 60 fullerene, solubility has been measured in solvents such as hexane, heptane, tetralin, carbon disulfide, n -butylamine, benzene, toluene, , o -xylene, o -dichlorobenzene, ,, 1,2,4-trichlorobenzene, 1,3-diphenylacetone, thiophene, tetrahydrothiophene, tetrahydrofurane, 1-alkanoic acids with normal structure, − 1-alkanols, styrene, carbon disulfide, ,, and natural fats and oils. , Solubility of the C 70 fullerene as a function of temperature has been investigated in the following solvents: heptane, tetralin, toluene, ,, o -xylene, o -dichlorobenzene, 1,3-diphenylacetone, , 1-alkanoic acids, 1-alkanols, carbon disulfide, styrene, and natural fats and oils. , …”
