| titleOfInvention | Pd-Mg/C catalyst for catalytic hydrogenation of 2,3,6-trichloropyridine to produce 2,3-dichloropyridine and preparation method |
| abstract | The invention discloses a Pd-Mg/C catalyst for preparing 2,3-dichloropyridine by catalytic hydrogenation of 2,3,6-trichloropyridine and a preparation method. The catalyst is prepared by mixing Na 2 PdCl in the presence of sodium tartrate. 4 and MgCl 2 and the activated carbon carrier treated with hydrogen peroxide and hydrochloric acid are mixed and stirred, dried and then reduced with H 2 to obtain a Pd-Mg/C catalyst. The catalyst preparation process of the invention realizes that the nanometer metal is highly dispersed on the carrier, and the acid-base state of the catalyst surface is adjusted by the auxiliary agent Mg, the selectivity of 2,3-dichloropyridine is improved, and the relationship between the precious metal palladium and the carrier is enhanced at the same time. The interaction between the catalysts has good stability, improves the reuse performance of the catalyst, and is beneficial to reduce the production cost. |
