Usage

General Description

1,2,3-Trifluoropropane, also known as HFC-263fb, is a man-made chemical compound with the chemical formula C3H5F3. It is a colorless, odorless gas that is primarily used as a refrigerant in air conditioning and refrigeration systems. 1,2,3-Trifluoropropane is considered to be an environmentally friendly alternative to other refrigerants because it has a low global warming potential and ozone depletion potential. It also has a high energy efficiency and is non-flammable, making it a safer option for use in these applications. Additionally, it is used as a foam-blowing agent in the production of insulation materials and as a propellant in aerosol products. Despite its beneficial properties, 1,2,3-Trifluoropropane is a potent greenhouse gas and its use is regulated to prevent negative environmental impacts.

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.

REACTIONS OF CHLORINE MONOFLUORIDE. REGIOSPECIFICITY AND STEREOCHEMISTRY OF THE SUBSTITUTION OF BROMINE ATOMS BY FLUORINE IN HALOGEN-SUBSTITUTED ALKANES AND ESTERS

Under mild conditions without catalysts chlorine monofluoride substitutes bromine atoms for fluorine in bromine-substituted alkanes and esters.Electron-donating substituents promote the substitution reaction.The following sequence is observed in the reactivity of the bromine atoms at the carbon: tertiary > secondary > primary.Halogen atoms (Cl, F) at a carbon containing a bromine also promotes substitution of the latter by fluorine.The reactivity of the bromine atoms decreases in the following order: CCl2Br(CClFBr) > CHClBr(CHFBr) > CH2Br.An alkoxycarbonyl group at a carbon containing bromine prevents substitution.In a number of cases substitutive fluorination is accompanied by skeletal rearrangements and by migration of chlorine atoms.The stereochemistry of substitutive fluorination was studied for the case of the reaction of erythro- and threo-1-bromo-2-fluoro-1,2-dichloroethanes and 1,2-dibromo-1,3-dichloropropanes with chlorine monofluoride.The probable mechanism of the reaction is discussed.
