    摘要: 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: CH3—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.

    摘要: The present invention provides a process for preparing 3,3,3-trifluoropropene (1243zf), the process comprising: (a) fluorinating CCI3CH2CH2CI (250fb) to produce a reaction product comprising CF3CH2CH2CI (253fb) in the liquid phase in a first reactor, using HF as the fluorinating agent; and (b) (i) dehydrohalogenating 253fb to produce 1243zf in the vapour phase in the presence of a catalyst in a second reactor; or (b) (ii) dehydrohalogenating 253fb to produce 1243zf in a second reactor, wherein the reaction product comprising 253fb produced in step (a) has subjected to one or more purification steps before step (b). The present invention also provides an azeotropic or near-azeotropic composition comprising HF and 253fb.
