METHOD OF PRODUCING MONOFLUOROMETHANE
20230159415 · 2023-05-25 · ·

Provided is a production method that enables production of monofluoromethane by a gas phase flow method without using a catalyst. The method of producing monofluoromethane includes causing electrical discharge of a feedstock gas containing a fluorine-containing inorganic compound, a compound represented by formula 1: CH.sub.3—R (R is a hydrogen atom, a chlorine atom, a bromine atom, an iodine atom, or an organic group other than a hydrocarbon group), and an inert gas, while in a continuous flow state, and then causing continuous release to outside of an electrical discharge zone.
