    摘要: Provided is an industrially simple and cheap method for efficiently removing butene from crude monofluorobutane containing butene without causing substantial decomposition, transformation, or the like of the monofluorobutane. In a provided monofluorobutane purification method, crude monofluorobutane containing butene is brought into contact with trihalomethane in the presence of an alkali aqueous solution to convert the butene to a compound having a higher boiling point than the monofluorobutane, water is subsequently added to a reaction mixture obtained thereby to dissolve a produced salt, an organic layer is separated, and then the separated organic layer is purified by distillation.

    摘要: The present invention is a method for producing a fluorinated hydrocarbon represented by a structural formula (3), wherein an ether compound represented by a structural formula (1) and an acid fluoride represented by a structural formula (2) are brought into contact with each other in a hydrocarbon-based solvent, in the presence of a catalyst in which boron trifluoride is supported on a metal oxide: wherein R 1 and R 2 represent an alkyl group having 1 to 3 carbon atoms, R 3 represents a hydrogen atom, a methyl group or an ethyl group, and R 4 and R 5 represent a methyl group or an ethyl group; and R 1 and R 2 may be bonded to each other to form a cyclic structure. Through the present invention, a method for industrially advantageously producing 2-fluorobutane is provided.
