| titleOfInvention | A kind of preparation method of steroid compound catalyst for hydrogenation and application |
| abstract | The invention discloses a kind of preparation method of steroid compound catalyst for hydrogenation, the method is: one, the pretreatment of active carbon; Two, the soluble-salt of soluble palladium compound and auxiliary agent is dissolved in the water, stirs and obtain precursor solution; Three, pretreated absorbent charcoal carrier is added in precursor solution, after dipping, regulate the pH of dipping system, filter after continuing to stir 1h ~ 5h, washing leaching cake; Four, washing is pulled an oar to neutral filter cake pure water, obtain slurry, regulate described slurry pH value, add reducing agent and reduce, washing after filtering, dry, obtain steroid compound catalyst for hydrogenation.In addition, the invention also discloses the method for this catalyst for catalysis steroid compound hydrogenation.Catalyst prepared by the present invention is applicable to steroid compound catalytic hydrogenation, and product yield is more than 95%, and the mass percentage of Isomers In Products is less than 5%, and catalyst performance stabilised has good repeatability. |
