沸石催化苯胺苯核烷基化反应的研究

Bing Alkylation of Aniline in the Presence of Zeolite

用高压反应釜结合气相色谱、气相色谱－质谱联用、气相色谱－红外联用等分析技术探讨了环己烯和苯胺在不同酸度Ｙ型沸石上的烷基化反应。结果表明，于选定的试验条件下，可选择性地生成邻位烷基化产物，其烷基化活性和选择性与催化剂的质子酸度有关。

The alkylation of aniline with cyclohexene in the presence of Y zeolite was carried outin an autOclave. The products were characterized using GC-MS,GC-IR and other techniques. The results show that acidic Y zeolites have good performance in catalysing this reaction,ofwhich the major product is ortho-alkylated aniline,The conversion of aniline and theselectivitv are reJated to the aciditv of the zeolite.
