| titleOfInvention | Method for preparing catalyst for preparing 1,1,5-trihydroperfluoropentyl methacrylate |
| abstract | The invention discloses a method for preparing a catalyst for preparing 1,1,5-trihydroperfluoropentyl methacrylate. According to the method, perfluorosulfonate ion-exchange resin is used as a carrier and then loaded with neodymium trifluoromethanesulfonate with a liquid-phase sedimentation method, meanwhile, a complexing agent is used for modification, and a product of the catalyst is produced. The perfluorosulfonate ion-exchange resin in the catalyst is a new kind of ion-exchange resin and has the advantages of high acidity, high thermal stability, high chemical stability and the like. The catalyst loaded with the neodymium trifluoromethanesulfonate has the good transesterification catalyzing performance. The complexation of the complexing agent and the neodymium trifluoromethanesulfonate can be realized under the acidic condition, so that neodymium ions are adsorbed on a resin matrix firmer and not prone to loss, and the service life of the catalyst is prolonged. |
