Low temperature synthesis method for graphite fluoride

Abstract

The invention discloses a low temperature synthesis method for graphite fluoride. The method includes: reacting graphite with antimony pentachloride at 300-400DEG C for 7h to prepare an antimony pentachloride graphite intercalation compound; and introducing a fluorine-nitrogen mixed gas into the reactor to carry out reaction for 5-10h, with the fluorine accounting for 12%-15% of the total volume of the fluorine-nitrogen mixed gas. The graphite fluoride synthesis reaction temperature is far below its decomposition temperature, thus avoiding the potential danger of explosion. Graphite fluoride can form in ordinary fluorination equipment, the reaction temperature control range is large and is easy to control. The production cost is low, and the output rate is high.

Description

[0001] technical field [0002] The invention belongs to the technical field of graphite, and in particular relates to a low-temperature synthesis method of fluorinated graphite. [0003] Background technique [0004] As a graphite deep-processing product, my country began to study fluorinated graphite as early as the 1970s. At present, the high-temperature synthesis method used in the production of fluorinated graphite is very unsafe for graphite and fluorine to react at high temperatures, and is accompanied by a large number of by-products. The yield of final fluorinated graphite is low. [0005] Contents of the invention [0006] In order to overcome the above-mentioned technical problems in the prior art, the object of the present invention is to provide a low-temperature synthesis method of graphite fluoride, which is safe in production and high in yield. [0007] The low-temperature synthesis method of fluorinated graphite provided by the present invention comprise...
