摘要
文章报导了甲苯定向催化硝化合成对一硝基甲苯的方法。在温和条件下,采用复合型催化剂,以硝酸为硝化剂,取得对位体与邻位体比值(P/O)为2.39的实验结果。与经典的混酸硝化法所得产物的 P/O 值0.63相比较,提高了1.76。
This paper introduces a new method by which stereospecific nitration of toluene with nitric acid catalyzed by the mixed catalyst yields mononitrotoluene of the high para-isomer content,with the result that stereospecific nitration catalyzed by complex cata- lysts gives higher para:ortho ratio (P/O 2.39) than the classical mixed acid nitration method (P/O 0.63).
