The nitration of phenolic compounds with 60% nitric acid (1.2 equiv) has been carried out in the presence of metal-modified montmorillonite KSF, prepared from different metals (V, Mo, W; Sc, La, Yb, Eu, In, Bi, Ti, Zr, Hf) and KSF or nitric acid treated HKSF, as catalysts. These catalysts showed good stabilities and high catalytic activities in nitration process. In addition, these catalysts can be
酚类化合物与60%硝酸(1.2当量)的硝化反应是在金属改性的蒙脱土KSF的存在下进行的,该蒙脱土KSF由不同的金属(V,Mo,W,Sc,La,Yb,Eu,In,Bi, ,Ti,Zr,Hf)和KSF或硝酸处理的HKSF作为催化剂。这些催化剂在硝化过程中表现出良好的稳定性和较高的催化活性。另外,这些催化剂可以容易地回收并在硝化中重复使用多次。该方法是清洁合成硝化酚类化合物的一种生态安全且对环境有益的方法。
