General Description

2-Fluorobutane, also known as fluorinated butane, is an organic compound with the chemical formula C4H9F. It is a colorless and odorless gas at room temperature and is commonly used as a refrigerant in air conditioning systems. 2-Fluorobutane is also used in the production of various chemical compounds, including pharmaceuticals and pesticides. It is considered a volatile and flammable substance, and proper precautions should be taken when handling and storing it. In addition, 2-Fluorobutane is known to be a greenhouse gas, contributing to the depletion of the ozone layer and global warming, and its production and use are regulated under environmental laws.

BUTENE CONVERSION METHOD AND MONOFLUOROBUTANE PURIFICATION METHOD

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.

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.

METHOD FOR PRODUCING FLUORINATED HYDROCARBON

PROBLEM TO BE SOLVED: To provide a method for industrially advantageously producing a fluorinated hydrocarbon. SOLUTION: The method for producing a fluorinated hydrocarbon represented by formula (3) comprises bringing a secondary or tertiary ether compound represented by formula (1) into contact with an acid fluoride represented by formula (2) in the presence of a compound having an N-X bond (X is a halogen atom selected from a chlorine atom, a bromine atom, and an iodine atom) in a halogenated hydrocarbon-based solvent. (R1 and R2 are each independently a C1-C3 alkyl group; R3 is H, a methyl group, or an ethyl group; R4 and R5 are each a methyl group or an ethyl group; and R1 and R2 may be bonded together to form a ring structure.)
