| titleOfInvention | With NiMe2Method for preparing polyvinyl carbazole by taking-BOC as catalyst |
| abstract | With NiMe 2 A method for preparing polyvinyl carbazole by using BOC as a catalyst, which belongs to the technical field of organic luminescent materials. In the process, NiMe is introduced in the reaction process of polymerizing N-vinyl carbazole to obtain polyvinyl carbazole 2 The BOC is used as a catalyst to obtain a high-density target product, the production flow is greatly simplified, and the molecular weight of the obtained polyvinylcarbazole is much higher than that of the conventional technical process. Compared with a noble metal catalyst, the nickel adopted in the process is a fourth transition metal, the process has the unique advantages of high natural abundance, low toxicity, strong Lewis acidity and the like, and the catalyst can not be inactivated after continuously working for at least 12 hours, so that the reaction time is shortened. The final product is white crystalline powder; no odor, and high purity. The total yield of the reaction reaches up to 76%, and the yield is greatly improved. The process is greatly simplified, the production cost is reduced, the experimental safety is ensured, the purpose of saving energy is achieved, and the modern chemical production requirement of green reaction is met. |
