Abstract

The present invention relates to multistep syntheses of hexafluoropropylene from hexachloropropylene. In all these syntheses the first step is a fluorination of the starting material; later steps convert the initial products to CF.sub.3 --CFCl--CF.sub.3, which is dehalogenated to the desired product.
