| titleOfInvention | A kind of Catalysts and its preparation method of methyl nitrite formylated synthesis methyl formate and application |
| abstract | The invention discloses a kind of loaded catalyst for the reaction of methyl nitrite formylated synthesis methyl formate, comprise hydrogenation palladium active component, carrier and optionally auxiliary agent.In the quality of carrier, the percentage composition of active component hydrogenation palladium is 0.01-2%, and the percentage composition of auxiliary agent is less than or equal to 20%.The invention also discloses a kind of preparation method of the catalyst for the reaction of methyl nitrite formylated synthesis methyl formate, preparation process is as follows: optionally by carrier impregnation to the water or ethanolic solution of auxiliary agent presoma, standing, dry, roasting; In the water being impregnated into palladium presoma again or ethanolic solution, stir, make carrier be distributed in palladium precursor solution equably; The ultrasonic volatilization of the solvent to solution is dry in a heated condition, makes palladium presoma be adsorbed onto carrier surface equably; The adsorption sample obtained is dry, roasting; Then under high-purity hydrogen atmosphere, reduction obtains support type hydrogenation palladium catalyst. |
