Procedure
In the form of the present invention starting from hexafluoropropylene oxide, a vapor stream of hexafluoropropylene oxide is fed at any convenient flow rate, e.g., in the range of about 0.04 to about 0.06 g-mole/hr to a reactor maintained at a temperature in the range of about 400° to about 650° C. and containing a fluorinated catalyst (hereinafter described) for a residence time sufficient to for a vapor stream comprising hexafluoroacetone which is not isolated but forwarded directly to a heating zone of the reactor for conversion to hexafluoroisobutylene.
