Document Type and Number:
Japanese Patent JPH06505237
Kind Code:
A
Abstract:
A vapor phase process is disclosed for producing HCFC-225s, HCFC-235s, HCFC-226s, HFC-236s, and HFC-227s by reacting certain three-carbon reactants containing at least one less fluorine than, and at least as many hydrogen substituents as the desired product (e.g. propane propylene, allene or methylacetylene) with Cl2 and HF in the presence of a catalyst consisting essentially of chromium oxide or of chromium oxide which is combined with a refractory oxide, fluorinated and/or modified with manganese, iron, cobalt, nickel, copper and/or zinc. The temperature and contact time for the reaction are chosen to provide a product having the desired fluorine and hydrogen content.
