Abstract
A process for the dehydrohalogenation of saturated hydrogen-containing polyhalocarbons using liquid alkali metal acid fluoride and/or alkali metal fluoride compositions to form haloolefins.
Claims7
A process for preparing haloolefins containing a single double bond and at least one halogen substituent attached to an unsaturated carbon atom, which process comprises the following steps:
- (1) contacting component (A) a saturated halohydrocarbon having a hydrogen substituent and a halogen substituent on adjacent saturated carbon atoms and at least one other halogen substituent on at least one of the adjacent saturated carbon atoms with component (B) a substantially molten alkali metal acid fluoride or a molten mixture thereof with an alkali metal fluoride.
