ABSTRACT:
An improved synthesis of carbon fluoride CF.sub.x, and carbon fluoride chloride, (C.sub.y F.sub.x Cl.sub.z).sub.n, is described. Direct fluorination of the intermediate (C.sub.y F.sub.x Cl.sub.z).sub.n (x.ltoreq.0.7, y.ltoreq.1 and z.ltoreq.0.1) in the absence of chlorine produces, either CF.sub.x (x.gtoreq.1) or (C.sub.y F.sub.x Cl.sub.z).sub.n (x.gtoreq.0.9, y=1, z.ltoreq.0.01) in as brief a period as 1 hour. The final CF.sub.x product is novel and exhibits improved properties compared to CF.sub.x made via conventional methods. The novel process for producing carbon fluoride chloride is more economical than prior art methods.
