本文研究了咪唑以负离子形式负载于氧化铝表面,并进行咪唑的N—烷基化反应,得到八个N—烷基化产物,一般收率在70％以上。研究了不同卤代烃的结构及反应温度对产率的影响。 In this paper, Imidazole was supported on the surface of alumina in the form of negative ions and the N-alkylation of imidazole was carried out to obtain eight N-alkylated products with a yield of more than 70%. The structure of different halogenated hydrocarbons and the effect of reaction temperature on the yield were studied.
