| titleOfInvention | Method for preparing perfluorodiene and perfluoroalkyne through gas phase isomerization |
| abstract | The invention relates to a method for preparing perfluorodiene and perfluoroalkyne by gas phase isomerization, which takes perfluorocycloalkene as a raw material and takes a gas phase isomerization reaction in the presence of an isomerization catalyst to obtain perfluorodiene and perfluoroalkyne. The method has the advantages of low isomerization catalyst cost, high conversion rate and high selectivity synthesis of the perfluorodiene or the perfluoroalkyne by controlling the reaction temperature, suitability for large-scale gas-phase reaction preparation of the perfluorodiene and the perfluoroalkyne, and particular suitability for large-scale gas-phase reaction preparation of the hexafluoro-1, 3-butadiene and the octafluoro-1, 3-pentadiene. |
