Usage

General Description

1,1,2,2-Tetrafluoropropane, also known as norflurane, is a colorless, non-toxic, flammable gas with a faint ether-like odor. It is primarily used as a refrigerant and a blowing agent in foam insulation. It has a relatively low global warming potential and is considered to be an environmentally friendly alternative to other fluorocarbons. It also has a low ozone depletion potential, making it a suitable option for use in various industrial applications. Additionally, 1,1,2,2-Tetrafluoropropane is used as a propellant in aerosol products and as a fire suppression agent in fire extinguishing systems.

Fluorination of propane and propene over cobalt(III) trifluoride and potassium tetrafluorocobaltate(III)

Fluorination of propane and propene over cobalt(III) fluoride and potassium tetrafluorocobaltate(III) gave complex mixtures of products which have been identified to the 0.5percent level.The reactions are valuelles for preparative purposes.The mechanism of the fluorinations is not a simple F-for-H replacement, but requires an initial conversion of propane into propene followed by carbocation- and radical mediated reactions: the carbocations can be quenched by fluoride ions, rearrange and eliminate, and the radicals can be oxidised to carbocations or quenched by fluorine atoms.Radical quenching tends to predominate late in the fluoronation and carbocation reactions at the beginning.

HOMOLYTIC TRANSFORMATIONS OF FLUORINE-CONTAINING ACETALS

Study of the homolytic transformations which occur during the dissociation of di-tert-butyl peroxide in linear fluorine-containing acetals (derivatives of 2,2,3,3-tetrafluoropropanol and 2,2,3,3,4,4,5,5-octafluoropentanol) shows that the reactivity of the molecule of the fluorine containing acetal is determined mainly by the C-H bonds adjacent to the two oxygen atoms, and the products from the fragmentation of the obtained dialkoxyalkyl radicals are fluorinated esters and alkyl radicals.The abstraction of a hydrogen atom from the molecules of the oligomeric formalsH(CF2)n(OCH2)mOCH2(CF2)nH leads to the dialkoxyalkyl radicals, which undergo fragmentation at the C-H bonds at the β position to the radical center with the formation of oligomeric esters H(CF2)n(OCH2)iOC(O)H (i = 1...m).
