Usage

General Description

Heptafluoro-n-propyl bromide, also known as HFPB or Perfluoro-n-propyl bromide, is a chemical compound with the molecular formula C3F7Br. It is a colorless, odorless, non-flammable liquid with a boiling point of 47°C and a relatively low toxicity. HFPB is primarily used as a replacement for ozone-depleting substances in various applications, including as a refrigerant, solvent, and propellant. It is also utilized in the production of specialty chemicals and pharmaceuticals. HFPB exhibits low global warming potential and ozone depletion potential, making it an environmentally friendly alternative to other halogenated compounds. However, it is important to handle HFPB with care and follow safety guidelines due to its potential for harmful effects if not properly controlled.

Addition of trifluoromethanes to fluoroolefins and isomerization of monohaloperfluoro alkanes

A process for the Lewis acid catalyzed addition of trifluoromethanes across the carbon-carbon double bond of fluoroolefins is disclosed. A process for isomerization of monohaloperfluoro alkanes is also disclosed.

BROMINATION OF FLUOROALKENES PART 5.-KINETICS OF FORWARD AND REVERSE REACTIONS IN THE SYSTEM Br2+i-C3F7HHBr+i-C3F7Br

The kinetics of the forward and reverse reactions in the gas-phase system have been studied.The slow steps for the forward and reverse reactions, respectively, are .The Arrhenius parameters obtained, for the range 421-534 deg C, are .The competitive brominations of mixtures of i-C3F7H+C2F5H and i-C3F7H+n-C3F7H have been studied over the ranges 249-430 and 220-402 deg C, respectively.Each system yielded Arrhenius parameters for reaction (2) which are in excellent agreement with those given above.The results lead to the following bond dissociation energies at 298 K: Attempts were made to measure D using competitive photobromination and photochlorination.However, (CF3)3C-H is so unreactive that only the approximate result D ca. 456 kJ mol-1 was obtained.The trends in C-H and C-Br bond dissociation energies are compared in alkanes, fluoroalkanes and the corresponding bromides.
