摘要
用拉曼光谱研究了金属硝酸盐──醋酐硝化剂中的活化硝化成分，认为该体系中的活化硝化剂是硝鎓离子。利用气相色谱建立了该硝化剂在有机溶剂中进行硝化反应的Hammett方程，求得反应常数值p=-6.24。一定条件下该硝化剂具有较好的反应位置选择性，这一是由于反应介质低的介电常数，二是多孔载体也具有明显的作用。
With Laser Raman spectroscopy,the active nitrating agent in a system of metallic nitrates and acetic anhydride has been shown to be nitroninm.The Hammett equation for the nitration with this nitrating agent in an organic solvent has been established with the aid of gas chromatography,and the reaction constant has been obtained ρ=-6.24.In this system good regioselectivity can be achieved mainly because of the existence of a porous support and the low dielectric constant of the reaction media.
