| 摘要 |
<p>The present invention provides a process for producing a fluorine-containing alkyne compound represented by the formula: wherein Rf is a fluorine-containing alkyl group, the process including subjecting a fluorine-containing alkene compound represented by the formula: RfCX=CHY, wherein Rf is a fluorine-containing alkyl group, and one of X and Y is a halogen atom, and the other is a hydrogen atom, to a dehydrohalogenation reaction in a gas phase in the presence of at least one compound selected from the group consisting of alkali metal- or alkaline earth metal-containing halides; alkali metal- or alkaline earth metal-containing oxides; and alkali metal- or alkaline earth metal-containing hydroxides. This process can produce a fluorine-containing alkyne compound, such as 3,3,3-trifluoropropyne, with a high selectivity in a relatively simple manner.</p> |
