| titleOfInvention | The preparation method of p-aminophenyl-beta-hydroxyethyl sulfone catalyst for synthesizing and application |
| abstract | The invention discloses a kind of preparation method of p-aminophenyl-beta-hydroxyethyl sulfone catalyst for synthesizing, the method is: one, the pretreatment of active carbon; Two, palladium bichloride hydrochloric acid solution is prepared; Three, by pretreated active carbon water making beating, in slurry, palladium bichloride hydrochloric acid solution is dripped; Four, the slurry after dropping palladium bichloride hydrochloric acid solution is placed in microwave synthesizer, leave standstill, then adjust ph, adds reducing agent and carries out microwave reduction, filters, and washing leaching cake, to without chlorion, is dried, obtained p-aminophenyl-beta-hydroxyethyl sulfone catalyst for synthesizing.In addition, the invention also discloses this catalyst for catalyzing and synthesizing the method for p-aminophenyl-beta-hydroxyethyl sulfone.The catalyst to catalyzing hydrogenating synthesis p-aminophenyl-beta-hydroxyethyl sulfone adopting the method to prepare, catalytic efficiency is high, and product yield can reach more than 95%, and catalyst performance stabilised, there is good repeatability. |
