摘要
研究了KF/Al2 O3作为一种新型的碱性催化剂 ,对咔唑的N 乙基化反应进行的催化 ,在 60℃下反应 2h得到最佳收率为 33 1 7% (色谱数据 )。试验结果表明KF/Al2 O3对本反应的催化能力比传统催化剂要低 ,但是这种催化剂在反应中不产生废碱液 。
KF/Al 2O 3 has been used in the experiment of N ethylation of carbazole as a new kind of alkaline catalyst.The highest convertion of carbazole(33.17%) can be gained while the reaction lasted 2 hours at 60℃ in DMF solvent,which is lower than that of conventional catalyst.But KF/Al 2O 3 does not produce waste lye,so that it will not bring about environmental pollution.
