摘要：
An improved process for the reaction of hexafluoropropene with elemental sulfur and alkali metal fluoride such as KF, in an aprotic solvent selected from the group consisting of acetonitrile dimethylacetamide, dimethylformamide, dimethyl sulfoxide and N-methyl pyrrolidone under substantially one atmosphere pressure and at tempertures of between about 25.degree. and 100.degree. C. is disclosed. The preferred alkali metal fluoride is KF and the preferred aprotic solvent is dimethylformamide.
