摘要： A process is disclosed for producing perfluoroolefins of the formula CF(R1f)═CF2, where R1f is F or CF3. The process involves (a) perfluorinating cyclobutanes of the formula where R2f is F or CF3, and where one R1 is H and the other R1 is H when R1f is F and is CH3 when R1f is CF3, by the Simons electrochemical fluorination process in an electrochemical cell in a solution of anhydrous liquid hydrogen fluoride under temperature and pressure conditions sufficient to replace all hydrogens in the cyclobutane of the above formula with fluorine; and (b) cracking the perfluorinated cyclobutane. A disclosed cracking involves contacting the perfluorinated cyclobutanes with carbon or a conductive metal, which is heated by induction heating to a temperature sufficient to crack the perfluorinated cyclobutanes.
