Abstract:
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 4  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.

Claim (Index 2):
The production method according to  claim 1 , wherein the metal oxide is at least one selected from aluminum oxide, titanium oxide and zirconium oxide.
