| titleOfInvention | Supported condensation catalyst and preparation method thereof and use for synthesizing 1,3-butanediol |
| abstract | The invention provides a supported condensation catalyst, a preparation method thereof, and a use for synthesizing 1,3-butanediol, which solves the problem that the reaction liquid homogeneous catalyst is difficult to separate in other methods, requires later desalination treatment, or the solid catalyst is easy to corrode , the catalyst is easy to deactivate or the product selectivity is low, and it has the advantages of catalyst corrosion resistance, long catalyst life, high reaction conversion rate and high selectivity, and is suitable for industrial production. Specifically, under the conditions of normal pressure or slightly positive pressure and reaction temperature of 0 to 30 °C, acetaldehyde is converted into a condensation reaction product under the action of a supported condensation catalyst, and the condensation reaction product is further deacetaldehyde, hydrogenation and separation. The reaction product 1,3-butanediol is obtained. Wherein, the supported condensation catalyst is prepared by impregnation vacuum infusion method, the carrier is carbonized polyimide (CPI), and the active component is quaternary ammonium base. |
