Process for the preparation of halogenated hydrocarbons with at least 3 carbon atoms by reacting CFCl3 with an olefin

摘要

A telomerisation process is described whereby fluorotrichloromethane is added to olefins like 2-chloroprop-1-ene, preferably in the presence of a catalyst. The reaction products, e.g. 1,1,3,3-tetrachloro-1-fluorobutane, can be further fluorinated.
