Preparation method and application method of hexafluoropropylene dimer isomerization catalyst

The invention relates to a preparation method and an application method of a hexafluoropropylene dimer isomerization catalyst, and also relates to a recovery method of the hexafluoropropylene dimer isomerization catalyst, and the method comprises the following steps: preparing the hexafluoropropylene dimer isomerization catalyst by using surface-modified microporous solid alkali particles to loadboron-doped iron fluoride; the catalyst can be used for simply and efficiently isomerizing a hexafluoropropylene dimer with the D2 structure into a hexafluoropropylene dimer with the D1 structure, issafe and environment-friendly, can be recycled, does not contain precious metals and is low in cost, and the hexafluoropropylene dimer with the D2 structure in the isomerized hexafluoropropylene dimercannot be basically detected. And the catalyst is a very promising hexafluoropropylene dimer isomerization catalyst. 本发明涉及一种六氟丙烯二聚体异构化催化剂的制备及其应用方法，本发明还包括其回收方法，本方法使用表面改性的微孔固体碱颗粒负载硼掺杂的氟化铁制备出一种六氟丙烯二聚体异构化催化剂，能简单高效的将D结构的六氟丙稀二聚体异构化成
