METHOD FOR PRODUCING FLUORINATED HYDROCARBONS

Provided is a method for industrially advantageously producing a fluorinated hydrocarbon (3). The disclosed method for producing a fluorinated hydrocarbon represented by formula (3) includes bringing into contact, in a hydrocarbon-based solvent, a secondary or tertiary ether compound represented by formula (1) below with an acid fluoride represented by formula (2) in the presence of lithium salt or sodium salt (in the formulae, R1 and R2 each represent a C1-3 alkyl, and R1 and R2 may be bonded to each other to form a ring structure; R3 represents a hydrogen atom, methyl, or ethyl; and R4 and R5 each represent methyl or ethyl).

METHOD FOR MANUFACTURING FLUORINATED HYDROCARBON

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 R1 and R2 represent an alkyl group having 1 to 3 carbon atoms, R3 represents a hydrogen atom, a methyl group or an ethyl group, and R4 and R5 represent a methyl group or an ethyl group; and R4 and R2 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.
