Abstract

The invention provides a method for producing a fullerene through macroscopic quantity separation of a hydrocarbon system and relates to a method for producing fullerene. A crude fullerene sample undergoes ultrasonic washing and is filtered to obtain a refined fullerene sample, and toluene is added and dissolved; under nitrogen protection, 2-methyl-2-fosthiazate is added into the solution to react and reacts with high fullerenes C76, C78 and C84 to form sediment, the solution is filtered to obtain sediment A and filtrate A, and the sediment A undergoes pyrolysis under N2 protection to obtain high fullerenes C76, C78 and C84; 2-methyl-2-imidazolidine is added into the filtrate A; 2-methyl-2-imidazolidine reacts under nitrogen protection and then form sediment together with fullerenes C60 and C70, and the solution is filtered to obtain sediment B and filtrate B; the sediment B undergoes pyrolysis under N2 protection to obtain fullerenes C60 and C70; with toluene as a solvent, a product after the pyrolysis undergoes three-step high-temperature and low-temperature recrystallization to obtain fullerenes C60 and C70; and the filtrate B undergoes fullerene chromatographic separation and purification to obtain a pure fullerene hydride.

Description

technical field [0001] The invention relates to a method for producing fullerenes, in particular to a method for macro-separating hydrocarbon systems to produce fullerenes. Background technique [0002] Fullerene is the third allotrope of carbon besides graphite and diamond. Due to its unique hollow spherical cage structure, strong electron affinity, good solubility and stability, it is used in superconducting [1-2] , optics [3] ,Solar battery [4-6] ,biomedicine [7-8] and catalytic [9] and other fields have been widely used. Once a breakthrough is made in the application of fullerene and functionalized fullerene, it will surely promote the great progress of science and technology and make a great contribution to the development of human beings. [0003] The separation of fullerenes mainly uses high performance liquid chromatography and non-high performance liquid chromatography. High-performance liquid chromatography has good separation effect and fast speed, but the ...
