General Description

1-Fluoro-1,1,2-trichloroethane is a chemical substance that is known by various synonyms, including Monofluorotrichloroethane, Trichloromonofluoroethane, or its CAS number, 354-21-6. It's a volatile and colorless liquid that is chemically reactive. This chlorofluorocarbon compound is highly corrosive and toxic, and it poses both acute and chronic health hazards upon exposure. Its use is mainly associated with the manufacturing, industrial and scientific research settings. It is insoluble in water but soluble in alcohol and ether. The compound is non-flammable, though it can decompose to produce toxic fumes and gases upon exposure to heat or flame. Its potential for environmental harm is significant due to its ozone depletion potential.

Synthesis of 1,1,1-trifluoroethane by fluorination of 1-chloro-1, 1-difluoroethane

The subject of the invention is the manufacture of 1,1,1-trifluoroethane by fluorination or 1-chloro-1,1-difluoroethane with anhydrous hydrofluoric acid. The reaction is carried out in the liquid phase and in the presence of a fluorination catalyst.

Catalytic synthesis of 1,1,1,2-tetrafluoroethane from 1,1,1,2-tetrachloroethane - A mechanistic consideration

1,1,1,2-Tetrachloroethane and its fluorinated derivatives as well as trichloroethene are fluorinated by hydrogen fluoride in the presence of a pre-conditioned chromia catalyst. The reaction pathways are derived under different conditions. Fluorinated haloalkanes are formed both by dehydrochlorination/hydrofruorination mechanism as well as chlorine/ fluorine exchange mechanism. Thus, beside fluorinated alkanes considerable amounts of haloolefins occur in the product mixture. A survey is given on the reaction pathway showing dependence on the reaction conditions. It is discussed with respect to calculated thermodynamic data. Kinetic and mechanistic investigations of the isomerisation reactions of 1.1.2.2-tetrafluoroethane on a CFC-conditioned chromia catalyst are also presented. The desired 1.1.1.2- tetrafluoroethane can be obtained from its symmetric isomer in the presence of a chromia catalyst conditioned exclusively with chlorine-free fluorocarbons. Mechanistic information is obtained by employing DCl which behaves similar to HF during the consecutive isomerisation reaction of 1.1.2.2- tetrafluoroethane. Thus, it is most probable that dehydrohalogenation/hydrohalogenation processes (elimination/addition mechanism) are mainly responsible for the formation of the haloolefins and halocarbons observed on chromia.

REACTIONS OF CHLORINE MONOFLUORIDE. IV. ADDITION OF CHLORINE MONOFLUORIDE TO HALOGEN-SUBSTITUTED ALKENES

The reactions of chlorine monofluoride with halogenoethylenes (1,1-dichloro-, 1,2-dichloro-, trichloro-, and tetrachloroethylenes) and halogenopropenes ( 3-bromo-, 3,3,3-trichloro-, E- and Z-1,3-dichloro-, 3-chloro-2-methyl-, and perfluoropropenes) were investigated in inert solvents in the presence of ethyl acetate as external nucleophile.In all cases chloroacyloxy adducts were isolated and identified in addition to the chlorofluorination products, and this indicates an electrophilic mechanism for the chlorofluorination of polyhalogenoalkenes.Methyl chloromaleate, chlorofumarate, chlorofluoroethylenedicarboxylate, α,β-difluoroacrylate, and perfluoromethacrylate in anhydrous hydrogen fluoride form the corresponding chlorofluoro adducts with satisfactory yields, whereas the reaction takes place with difficulty in inert solvents.
