| titleOfInvention | A kind of method for catalyzing synthesis of biotin by a palladium-carbon catalyst with high mechanical activity |
| abstract | The invention discloses a method for catalyzing biotin synthesis by a palladium carbon catalyst with high mechanical activity. The method uses palladium carbon as a catalyst to catalyze biotin intermediate cis-2-oxo-1,3-dibenzyl-4- (4-carboxybut-1-ene) hexahydro-1H-thieno[3,4-d]imidazole hydrogenation to synthesize biotin, wherein the catalyst uses activated carbon as a carrier, and after the carrier is treated at high temperature in an ammonia atmosphere, it is Activated with hydrogen peroxide to obtain pretreated activated carbon; after dissolving the soluble palladium compound in water, adding a nitrogen-containing compound, refluxing and stirring to obtain a palladium precursor solution; after beating the pretreated activated carbon with alcohol water, adding a palladium precursor solution, and Add alkali to control the pH of the system to be 6-12, and then reduce with a reducing agent to obtain a palladium-carbon catalyst. Compared with the existing method, the method of the invention not only has high activity of the catalyst, but also has stable performance of the catalyst, which can greatly increase the number of times of biotin synthesis in production and application, and reduce the production cost. |
