Industrial Synthesis of Vinyl Fluoride VF Monomer

There are several methods to prepare VF monomer. One of the methods described in patent literature is a two-step method [79], The first step is the reaction of hydrogen fluoride with acetylene in the presence of a suitable catalyst to yield ethylidene fluoride, which is subsequently pyrolyzed  

Other methods are described in [80] however, the commercial process for the synthesis of vinyl fluoride is not described in the literature for proprietary reasons [80], Addition of HF to acetylene and fluorination of vinyl chloride are the most likely industrial routes to the production of VF [81], 

As with TFE, it is essential that the VF monomer be purified prior to polymerization [80],
