Uses

Used in Fire Suppression Systems:
2,3-Dichlorooctafluorobutane is used as a gaseous fire suppression agent in extinguishing systems for its ability to rapidly remove heat and chemically inhibit combustion processes, making it highly effective in controlling and extinguishing fires.
Used in Various Industries:
In industries such as aviation, where sensitive equipment and high-value assets require protection from fire, 2,3-Dichlorooctafluorobutane is used as a fire suppression agent for its quick response and effectiveness in preventing fire damage.
However, due to its contribution to ozone depletion, 2,3-Dichlorooctafluorobutane is being phased out, and more environmentally friendly alternatives are being sought and developed for use in fire suppression systems. Additionally, exposure to this chemical can be harmful to human health, necessitating proper handling and safety precautions during its use.

A Novel Hydrodechlorinative Dimerization of Chlorofluorocarbons over Supported Ni Catalysts

1,1,1-Trichloro-2,2,2-trifluoroethane or 1,1-dichloro-1,2,2,2-tetrafluoroethane, both of which have CF3 group, dimerizes over supported Ni catalysts at an elevated temperature (723 K) into corresponding C4-compounds in good to moderate yields.

FLUORINATION OF POLYHALOGENATED UNSATURATED COMPOUNDS WITH VANADIUM PENTAFLUORIDE

Vanadium pentafluoride reacts with polyfluorinated and polychlorinated olefins, alkadienes, cycloalkenes and cyclodienes in CFCl3 or without a solvent at -25 deg C to 100 deg C, forming products of addition of two fluorine atoms across the C=C bond.

REACTION OF POLYHALOGENATED UNSATURATED COMPOUNDS WITH VANADIUM PENTAFLUORIDE

Terminal polyhalogenoalkenes are fluorinated by vanadium pentafluoride at -20 to -30 deg C, whereas internal polyfluoroalkenes only react with vanadium pentafluoride when heated. 2-Chloropentafluoro-1,3-butadiene adds fluorine atoms predominantly at positions 1,4 under the influence of vanadium pentafluoride, but only the isomeric tetrafluorohexachlorobutanes are formed from perchloro-1,3-butadiene.Fluorination of perfluoroallylbenzene and perfluoro-β-methylstyrene takes place more rapidly in the side chain than in the aromatic ring.

Reaction of Bistrifluoromethylaminosulphenyl Chloride with Fluoro-olefins and Hexafluorobut-2-yne under Free-radical Conditions

Reaction of bistrifluoromethylaminosulphenyl chloride with unsymmetrical fluoro-olefins in daylight or under photochemical conditions gives both possible 1:1 adducts (ca. 1:1) arising from homolytic fission of the S-Cl bond.Addition to octafluorobut-2-ene and hexafluorobut-2-yne gives mixtures of the syn- and anti- adducts.
