Abstract

The invention relates to a process for producing carbonyl difluoride. This process includes the steps of (a) reacting carbon monoxide with a first metal fluoride in a reactor, thereby obtaining carbonyl difluoride and a second metal fluoride having in the molecule a fluorine atom number less than that of the first metal fluoride; and (b) reacting the second metal fluoride with fluorine in the reactor, thereby obtaining the first metal fluoride. The steps (a) and (b) are alternately repeated in the reactor, thereby repeatedly producing carbonyl difluoride.
