| titleOfInvention | Praseodymium-based magnetic catalyst and preparation method and application thereof |
| abstract | The invention provides a praseodymium-based magnetic catalyst, and a preparation method and application thereof, and belongs to the technical field of a synthesis method of gamma-valerolactone and preparation of related catalysts. The praseodymium-based magnetic catalyst prepared by the invention is used for catalyzing levulinic acid to prepare gamma-valerolactone through liquid phase hydrogenation, and has the advantages of high levulinic acid conversion rate, good product selectivity, stable catalyst, low reaction temperature, low reaction pressure, no active metal loss, no coke generation, easy separation and recovery, low cost and the like. The results of the examples show that the praseodymium-based magnetic catalyst provided by the invention has the reaction temperature of 110 ℃ and the H pressure of 2MPa 2 High concentrations of levulinic acid were almost completely converted under mild conditions of 4h and the selectivity was 100%. |
