摘要:
A process for the production of a hydro(halo)fluorocarbon which comprises heating an .alpha.-fluoroether in the vapor phase at elevated temperature. .alpha.-fluoroethers are obtained by reacting a non-enolisable aldehyde with hydrogen fluoride to form an intermediate and reacting the intermediate with an alcohol or a halogenating agent. Novel .alpha.-fluoroethers are also provided.
