| titleOfInvention | A kind of NHPI catalyst utilizing imide bond grafting and its preparation method and application |
| abstract | The invention discloses a NHPI catalyst utilizing imide bond grafting and its preparation method and application. The catalyst comprises SiO2 carrier and N-hydroxyphthalimide grafted on the SiO2 carrier, N -Hydroxyphthalimide is grafted on SiO2 carrier by imide bond; The preparation method of this catalyst comprises the following steps: (1) utilizes aminopropyltriethoxysilane modified carrier SiO2 surface, Obtaining the surface ammoniated carrier SiO 2 ‑APTES; (2) dissolving the ring-mounted dilianic anhydride and the surface ammoniated carrier SiO 2 ‑APTES in a solvent, and preparing the grafted anhydride through covalent imide grafting; ( 3) The grafted acid anhydride is imidized to prepare a grafted NHPI catalyst, which can be used as a recyclable catalyst in the preparation of acetophenone. The catalyst does not lose the active components in the catalytic reaction, has good stability, has high active site density, has good catalytic effect, and realizes the recyclable utilization of the catalyst. |
