CHLOROTRIFLUOROETHYLENE TELOMERIZATION PROCESS

摘要

Case 4751 WGG/smt 10/17/83 CHLOROTRIFLUOROETHYLENE TELOMERIZATION PROCESS An improved process for preparing telomers of chlorotrifluoroethy1ene comprises the solution telomerization reaction of chlorotrifluoroethylene 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 conditions and at a temperature in the range of from about 90.degree.C to about 150.degree.C. The crude telomer prepared by this process can be fluorinated to produce a stabilized oil or grease.
