| titleOfInvention | Preparation method of ceramic surface supported catalytic filler |
| abstract | A preparation method of ceramic surface supported catalytic filler comprises the following steps: 1) treating the surface of the ceramic Raschig ring packing: washing with alkali, washing with water to neutrality, drying, adding Tris-HCl buffer solution and anhydrous ethanol, soaking, adding tannic acid, aminosilane and vinyl silane, and heating for crosslinking; 2) preparing vinyl imidazole, a cross-linking agent and an initiator, immersing the raschig ring, knocking and oscillating the raschig ring under a negative pressure state, pre-curing the raschig ring, and filling the raschig ring and ethyl acetate into a digestion tank for treatment; 3) introducing sulfonic acid groups into the Raschig rings obtained in the step 2) through quaternization reaction, and exchanging the sulfonic acid groups with dilute sulfuric acid to obtain strong-acid Raschig rings with catalytic capability. The supported catalytic filler is prepared by the coordination of a pyrocatechol structure with high adhesiveness and vinyl silane and the in-situ grafting of polyimidazol sulfonate on the surface of ceramic, has high catalytic efficiency, can overcome the defects of high mass transfer resistance and the like of the traditional catalyst package, and has potential application value in the field of reactive distillation. |
