Method for producing perfluorocarbon |
摘要 |
A production method of perfluorocarbon comprising a main reaction step of making a hydrofluorocarbon and fluorine gas of raw materials react in vapor phase with each other to obtain a reaction product gas containing a perfluorocarbon and residual fluorine gas, and a fluorine gas removing step of making the reaction product gas effluent from the main reaction step contact a hydrofluorocarbon having a chemical equivalent not less than 1.1 mol times a chemical equivalent of the fluorine gas contained in the reaction product gas, thereby removing the fluorine gas.
