| titleOfInvention | Supported composite metal catalyst suitable for preparing acetamide through acetonitrile hydration reaction and preparation method and application thereof |
| abstract | The invention relates to the field of acetonitrile hydration reaction catalysts. A load type composite metal catalyst suitable for preparing acetamide by acetonitrile hydration reaction comprises metal oxide, additive and SiO2 carrier, wherein the metal oxide is 0.5-20 wt%, the additive is 0.1-1 wt%, the rest is SiO2, the metal oxide is one or more of Ni and Mn metal oxide and Mg, Ca, In, Ga, Bi and Zr oxide, and the additive is phosphorus or boron. The invention also relates to a preparation method and application of the catalyst. The invention develops a high-efficiency and low-cost catalytic method aiming at preparing acetamide by acetonitrile hydration, has simple process, no three wastes, target product selectivity of more than 99 percent, product acetamide purity of more than 99.7 percent and water content of less than 0.5 percent, and can completely reach the standard used by pharmaceutical enterprises. |
