Abstract
Official abstract text for this publication.
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, R 1 and R 2 each represent a C 1-3 alkyl, and R 1 and R 2 may be bonded to each other to form a ring structure; R 3 represents a hydrogen atom, methyl, or ethyl; and R 4 and R 5 each represent methyl or ethyl).
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a fluorinated hydrocarbon represented by formula (3) below, wherein an ether compound represented by formula (1) below and an acid fluoride represented by formula (2) below are brought into contact with each other in a hydrocarbon-based solvent, in the presence of lithium salt or sodium salt, (in formula (1) above, R 1 and R 2 each independently 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 represents a methyl group or an ethyl group; and R 1 and R 2 may be bonded to each other to form a cyclic structure), R 5 —COF (2) (in formula (2) above, R 5 represents a methyl group or an ethyl group), (in formula (3) above, R 1 to R 3 represent the same meanings as described above). 2. The production method according to claim 1 , wherein the lithium salt or the sodium salt is inorganic acid salt. 3. The production method according to claim 1 , wherein the ether compound represented by the formula (1) is sec-butyl methyl ether or t-butyl methyl ether. 4. The production method according to claim 1 , wherein the acid fluoride represented by the formula (2) is acetyl fluoride. 5. The production method according to claim 1 , wherein the fluorinated hydrocarbon represented by the formula (3) is 2-fluorobutane.
