| 摘 要： | 硝化研究的重要意义之一是探索更具选择性的方法。该文讨论了应用同体酸催化剂和载体，在醋酐存在下，采用硝酸盐和载体硝酸盐硝化甲苯和氯苯的选择性．8种金属硝酸盐中，硝酸铜表现好的硝化特性。层状粘士较沸石分子筛、杂多酸盐等是颇具前景的芳烃选择性硝化催化剂和载体．四氯化碳和甲苯为较好的溶剂介质．阻此条件，甲苯和氯苯的划邻硝化产物比例分为1.2和5.6，较之硝硫混酸的结果（甲苯0.6，氯苯1.8）．其对位硝化能力显著提高。

| Abstract: | One of the main goals of modern nitration methodology is to increase its regioselectivity. The regioselective nitration of toluene and chlorobenzene w ith nitrates and supported nitrates on solid acid catalysts and supports in the presence of acetic anhydride is studied. Clays are promising solid acid catalysts and supports. Cupric nitrate possesses the best reactivity. Carbon tetrachloride and toluene appear to be the optimum solvents. Para selectivities are much improved, up to para-to-ortho ratios of 1.2 for toluene and 5. 6 for chlorobenzene. |
