General Description

Perfluorotetradecane is a fluorinated compound with the chemical formula C14F30. It is a colorless, odorless, and non-toxic liquid with a high boiling point. Perfluorotetradecane is used in various industrial applications, including as a lubricant, in the production of coatings and films, and as a component in specialized electronics and semiconductor manufacturing. Because of its unique properties, such as resistance to heat and chemical inertness, it is also used in research and development for applications in the aerospace and medical industries. However, perfluorotetradecane is a fluorinated compound, which has raised some environmental and health concerns due to its potential persistence and bioaccumulation in the environment.

Preparation method for perfluoroalkane

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.

Nucleophilic Displacement of Bis(perfluoroalkanoyl) Peroxides with Perfluoroalkanoate

Bis(perfluoroalknoyl) peroxide ((RFCO2)2) suffered a nucleophilic displacement with perfluoroalkanoate (RF'CO2(1-)) to give new mixed peroxide (RF(CO)OO(CO)RF').When thiophene was reacted with bis(perfluoroalkanoyl) peroxide in the presence of pyridinium perfluoroalkanoate, not only the perfluoroalkyl group (RF) of the peroxide, but also perfluoroalkyl group (RF') of perfluoroalkanoate, was introduced into thiophene.

Thermal Decomposition of Some Perfluoro- and Polyfluorodiacyl Peroxides

Seven polyfluoroacyl peroxides were synthesized, some of them by a new procedure involving the direct interaction of an acyl fluoride with hydrogen peroxide.In the temperature range of 20-40 deg C, all these peroxides undergo first-order decomposition in dilute 1,1,2-trichloro-1,2,2-trifluoroethane (Freon-113) solutions (F-RF.Differing from other perfluoro or polyfluoro radicals, the perfluoro-α-isopropoxyethyl radicals (10) undergo substantial β scission to form perfluoroisopropyl radicals (11) during their lifetime.The ΔHexc. values for the perfluoroacyl peroxides are about 24 kcal mol-1, or about 5 kcal lower than that of the nonfluorinated diacyl peroxides (ca. 29 kcal mol-1).Apparently, the higher relative rates for 3 and 7 are caused by different factors.The latter peroxide (7) decomposes with a more favorable ΔSexc. term, whereas the former (3) decomposes with lower values of both ΔHexc. and ΔSexc..Thus, weakening of the peroxide bond by H bonding of the peroxide oxygen atom with the acidic ω-hydrogen atom seems to be implicated in the decomposition of 3.With a half-life of 81 min at 20 deg C, 3 may become a useful low-temperature initiator for free-radical reactions and polymerization.
