Thermal decomposition of 2-nitro-2-nitrosopropane (4) in F113 (CCl2F-CClF2) solution involves C-NO bond fission and forms acetone as the major product.In the presence of polyfluorodiacyl peroxide (3), the oxidation of 4 by 3 to 2,2-dinitropropane (5) is the predominant reaction and bis(polyfluoroalkyl) nitroxide (1) is generated as one of the by-products.

Paragraph 0026; 0027, (2016/11/28)
The invention discloses a preparation method for perfluoroalkane. The preparation method comprises the following steps: adding a fluorination reagent into a reaction vessel, stirring the fluorination reagent at room temperature, introducing fluorine-nitrogen gas mixture into the reaction vessel for activation of the fluorination reagent and continuing stirring for half an hour, wherein the concentration of fluorine gas in the fluorine-nitrogen gas mixture is 0.5 to 10%, and the molar weight of the fluorine-nitrogen gas mixture is 1 to 5% of the molar weight of the fluorination reagent; after completion of stirring, relieving residual pressure in the reaction vessel, and adding perfluoroalkyl halide and a solvent into the reaction vessel for a reaction at 150 to 200 DEG C for 5 to 10 h, wherein a mol ratio of perfluoroalkyl halide to the fluorination reagent is (1: 1) to (1: 2), and a mol ratio of perfluoroalkyl halide to the solvent is (1: 5) to (1: 15); and after a reaction product is obtained upon completion of the reaction, cooling the reaction product to room temperature and distilling the reaction product to obtain perfluoroalkane. The method provided by the invention has the advantages of simple equipment, high operation security, etc.
