Process for the synthesis of trifluoroethylene

Abstract

A catalytic process for the synthesis of trifluoroethylene from chlorotrifluoroethylene which comprises contacting chlorotrifluoroethylene with hydrogen in the presence of a catalyst consisting of palladium or platinum supported on extruded activated carbon.

1 . A process for preparing trifluoroethylene comprising contacting chlorotrifluoroethylene with hydrogen in the presence of a catalyst consisting of palladium or platinum supported on activated carbon, wherein the activated carbon is extruded activated carbon. 
     
     
         2 . The process according to  claim 1  wherein the catalyst consists of said palladium supported on said extruded activated carbon. 
     
     
         3 . The process according to  claim 1 , said process is carried out in the gas-phase by contacting a gaseous stream of said chlorotrifluoroethylene and said hydrogen, with the catalyst. 
     
     
         4 . The process according to  claim 3  wherein the concentration of said chlorotrifluoroethylene in the gaseous stream is comprised between 5 and 55% by volume. 
     
     
         5 . A catalyst consisting of palladium or platinum, supported on activated carbon, wherein that the activated carbon is extruded activated carbon. 
     
     
         6 . The catalyst according to  claim 5  wherein the amount of said palladium or said platinum supported on the extruded activated carbon is comprised between 0.05 and 5% by weight. 
     
     
         7 . The catalyst according to  claim 5  consisting of the palladium supported on activated carbon. 
     
     
         8 . The catalyst according to  claim 6  consisting of the palladium supported on activated carbon. 
     
     
         9 . The process according to  claim 3  wherein the gaseous stream of said chlorotrifluoroethylene and said hydrogen comprises an inert gas.
