クロロトリフルオロエチレンからのトリフルオロエチレンの合成方法

摘要

The present invention relates to the preparation of trifluoroethylene (VF3 or TrFE) by hydrogenolysis of chlorotrifluoroethylene (CTFE) in the gaseous phase over a group VIII metal catalyst deposited on a support. This method can be used to obtain VF3 in an economical manner in conditions which minimize the risk of explosion of this molecule. Using a catalyst containing a group VIII metal and, more specifically, containing Pd deposited on a support and a specific series of steps of separation and purification makes it possible to obtain excellent CTFE conversion rates and high selectivity in VF3 at atmospheric pressure and at low temperatures.
