Uses

Used in Fire Suppression Systems:
2-Bromoheptafluoropropane is used as a gaseous fire suppression agent for protecting mission-critical facilities such as data centers, museums, and telecommunications facilities. It is employed for its ability to release a gas that does not conduct electricity, disrupt the chemical chain reaction responsible for the fire, and leave no residue after discharge.
Used in Pharmaceutical Industry:
In the pharmaceutical industry, 2-Bromoheptafluoropropane is used as a propellant in metered-dose inhalers. It serves as an effective delivery mechanism for medications in the form of aerosols, providing a convenient and efficient means for patients to receive their treatments.
Despite the phasing out of its use as a fire suppressant due to environmental concerns, 2-Bromoheptafluoropropane continues to be utilized in specific applications where other alternatives are not suitable, highlighting its versatility and importance in certain industries.

Addition of some unreactive fluoroalkanes to tetrafluoroethylene.: Direct catalytic synthesis of F-butene-2

Condensation of trifluoromethanes, CF3X (X=H, Cl, Br, I), with tetrafluorethylene to form the corresponding F-n-propyl adducts have been carried out with aluminum chlorofluoride as catalyst. Yields of C3F7I and C3F7Br are especially good, making these useful perfluoropropyl intermediates readily available. Details of the reactions, especially the presence of low percentages of perfluoroisopropyl iodide and bromide in the products, are accounted for by proposed mechanisms involving halonium intermediates. Longer-chain primary iodides can also be added to tetrafluoroethylene, but the final products are predominantly fluoroolefins, with pentafluoroethyl iodide as a byproduct. In the case of the addition of C2F5I to tetrafluoroethylene, conditions for an efficient, low temperature dimerization of terafluoroethylene to F-butene-2 catalyzed by a combination of C2F5I/aluminum chlorofluoride have been defined. Evidence for an unusual transfer of I+ from the iodonium derivative of F-butene-2 to tetrafluoroethylene is presented.

Pyrolysis of branched-chain perfluoroalkanes in the presence of halogens

The thermal decomposition of some highly branched perfluoroalkanes in the presence of molecular halogens (Cl2, Br2, I2) has been studied.The clear-cut cleavage of the most hindered carbon-carbon bond and the trapping by halogens of the intermediate radicals so formed account for the product distribution.Kinetic measurements support a mechanism based on homolytic rupture of the perfluoroalkanes as the rate-determining step, followed by the fast reaction of the intermediates with halogens.
