摘要
本文以咔唑和乙炔为原料,分两步制备N-乙烯基咔唑(N-vinylcarbazole,NVC),首先制备咔唑钾盐,然后以N-甲基-2-吡咯烷酮为惰性介质,常压下与乙炔加成得到NVC,乙醇重结晶后产品纯度在97%以上。
In this paper,N-vinylcarbazole(NVC)was prepared from carbazole and acetylene in two steps.Firstly,potassium carbazole was prepared.Then,NVC was obtained by adding acetylene to the potassium carbazole at atmospheric pressure with N-methyl-2-pyrrolidone as the inert medium.The purity of NVC was over 97%after recrystallization with ethanol.
