摘要
用铁、镁对ＮａＺＳＭ－５分子筛进行改性，并将改性分子筛用作硝疏混酸对甲苯进行一段硝化反应的催化剂，可以使产物中对硝基甲苯的单程收率提高约１０％。
The surface of zeolite NaZSM-5 were modified by using Fe and Mg re-spectively and catalysts of type Ⅰ and Ⅱ were obtained therefrom,In mononitration oftoluene with nitric-sulfuric acid mixture in the presence ofⅠor Ⅱ,p-mononitrotoluenein the nitration products could increased 10%。 The experimental results and the effectof catalyst Ⅰ and Ⅱ are discussed,compared with the conventional porous materials.
