Case 4751 WGG/smt 10/17/83 CHLOROTRIFLUOROETHYLENE TELOMERIZATION PROCESS ABSTRACT An improved process for preparing telomers of chlorotrifluoro- ethy1ene comprises the solution telomerization reaction of chloro- trifluoroethylene with carbon tetrachloride in the presence of a catalytic amount of cupric chloride (CuC12) and an iron reductant. Preferably, the solvent for the system comprises acetonitrile, and the telomerization is carried out under elevated pressure condi- tions 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 fluori- nated to produce a stabilized oil or grease.
