| Uses | N-vinylcarbazole is an important nitrogen-containing aromatic heterocyclic compound with special photoelectric properties and organic photoelectric functional materials The performance is more consistent, has a strong intramolecular electron transfer function, and its thermal stability is also relatively good. It is an important intermediate for the synthesis of photoelectric materials and is widely used in liquid crystal display materials. N-vinylcarbazole is a monomer raw material for the synthesis of polyvinyl carbazole (PVK). Pharmaceutical intermediates are also important intermediates for the synthesis of optoelectronic materials Liquid crystal display materials |
| preparation | preparation of solid super alkali Na-NaOH/γ-AlO: 100gγ-AlO is added to the reaction kettle, under the conditions of strong stirring and nitrogen purging, slowly heat and raise the temperature to 100 ℃, and keep for 1h to remove adsorbed water on the surface of the carrier. Then raise the temperature to 200 ℃, add 30g NaOH under strong stirring and nitrogen purging conditions, and keep it for 1h. After that, quickly add 10g of sodium metal and continue stirring for 1h. Cooling to obtain solid super alkali Na-NaOH/γ-AlO catalyst. 34g of reactant carbazole, catalyst Na-NaOH/γ-AlO and 200mL xylene were added to the reactor, and the sample quantity of the catalyst was 0.68g. Start the stirring function of the heating stirrer to make the three mix evenly, start the heating function of the heating stirrer to heat to 135 ℃, open the air guide pipe under normal pressure to pass acetylene gas, control the acetylene gas flow rate to 30 mL/min, make the liquid surface have slight bubbles released, and cool the reaction liquid to room temperature after 8 hours of reaction; Filter, separate the liquid phase and solid phase catalyst, the solid catalyst can be reused after separation, and the liquid phase is distilled under reduced pressure, the temperature was 154 ℃, and 31.4g of N-vinylcarbazole product was collected with a yield of 83%. the catalyst obtained by the above recovery is used again in the above-mentioned catalytic carbazole and acetylene reaction, and the final product N-vinylcarbazole product 30.4g is obtained without changing the above-mentioned reaction conditions. |
