| titleOfInvention | Gold-based catalyst, preparation method and application thereof |
| abstract | The invention provides a gold-based catalyst, a preparation method thereof and application thereof in MDA (multidrug resistance) preparation reaction, which is characterized by comprising a carrier, and an active component and an auxiliary agent which are loaded on the carrier; the carrier is hydroxide of aluminum; the active component is gold, and the content is 0.1-10 wt.%; the auxiliary agent is iron or the oxides of iron and iron. In the process of preparing methylacrolein dimethyl acetal by using methanol, methylacrolein and oxygen as raw materials, the gold-based alloy catalyst has the advantages that the conversion rate of methylacrolein can reach more than 80%, the selectivity of MDA reaches more than 90%, compared with the prior art, the yield of MDA is greatly improved, and the large-scale industrial preparation of MDA is realized. |
