METHOD FOR PRODUCING FLUOROSUBSTITUTED HYDROCARBON Russian patent published in 1998 - IPC

FIELD: organic chemistry. SUBSTANCE: fluorosubstituted (halogen-containing) hydrocarbon is produced by contacting $$$-substituted ether in vapor phase at elevated temperature with catalyst, followed by subjecting catalyst to regeneration treatment in order to maintain and/or restore its activity. Regeneration treatment of catalyst resides either in heating the latter to elevated temperature in excess of about 250 C in absence of $$$-fluorosubstituted ether, or in contacting catalyst at elevated temperature with oxidant during period or inbetween periods of contacting $$$-fluorosubstituted ether with catalyst. The latter may be constituted by oxidation-promoting metal, such as zinc, iron or copper deposited onto substrate made of metal oxide, fluoride or hydroxyfluoride. EFFECT: higher efficiency. 15 cl, 7 tbl
