Abstract
PURPOSE: The reaction between hexafluoropropene and hydrogen bromide is conducted in the presence of a catalyst of fluorinated alumina to produce in high selectivity the titled compound used as a crosslinkable modifier for fluorine rubber with reduced formation of the hydrobromide adduct of the titled compound.
CONSTITUTION: 1-Bromo-pentafluoro-1-propene is produced by reaction of hexafluoro-propene with hydrogen bromide in the presence of a catalyst of fluorinated alumina (fluorine content is 0.1W30wt%). The reaction temperature is 150W300°C. The amount of hydrogen bromide employed is 0.5W2mol par mole or hexafluoropropene. The fluorinated alumina is prepared by treating an activated alumina with a fluorinating agent such as chlorofluorocarbon at 150W450°C.
