ABSTRACT:
A novel gas phase process for the production of 1,1-dichloro-1-fluoroethane from vinylidene chloride and hydrogen fluoride is provided. The process is characterized by high conversion of vinylidene chloride to product, with a high selectivity for 1,1-dichloro-1-fluoroethane. The process may also be operated to selectively form 1-chloro-1,1-difluoroethane. Few volatile by-products and substantially no tar or oligomeric material is formed. Catalyst performance remains constant over extended periods of time.
