Preparation of high purity fluorinated peroxides

摘要

This invention is directed to an improvement in a process for producing high-purity fluorinated peroxides typically formed by the reaction of a carbonyl fluoride with a hypofluorite. The improvement resides in a simplified process for the synthesis and recovery of high purity fluorinated high purity peroxide product and comprises the steps: (a) reacting the carbonyl fluoride with the hypofluorite under conditions such that a gaseous reaction product comprised of the fluorinated peroxide and unreacted carbonyl fluoride which is essentially free of unreacted hypofluorite is formed; (b) removing unreacted carbonyl fluoride and by products from the gaseous reaction product under gas phase conditions thereby generating a gaseous product stream containing the fluorinated peroxide; and then, (c) collecting the fluorinated peroxide from step (b) in gas phase.
