| 摘要 |
PROBLEM TO BE SOLVED: To provide a new ether compound, especially, highly fluorinated fluoroether, which is saturated or unsaturated, and to provide a production method and the use for these ether compounds. SOLUTION: The method for preparing the fluoroether comprises a step of providing a halogenated ether intermediate represented by the general formula R<SP>5</SP>CXY-O-R<SP>6</SP>and containing at least one halogen selected from I, Br and Cl, and a step of fluorinating the halogenated ether intermediate in the presence of HF and a catalyst.
