Chlorotrifluoroethylene telomerization process.

摘要

An improved process for preparing telomers of chlorotrifluoroethylene comprises the solution telomerization reaction of chlorotrifluoroethylene with carbon tetrachloride in the presence of a catalytic amount of cupric chloride (CuCl<Sub>2</Sub>) and an iron reductant.-Preferably, the solvent for the system comprises acetonitrile, and the telomerization is carried out under elevated pressure conditions and at a temperature in the range of from about 90°C to about 150°C. The crude telomer prepared by this process can be fluorinated to produce a stabilized oil or grease.
