Abstract
Nitration of phenolic compounds by metal salts impregnated Yb-Mo-montmorillonite KSF
Highlights
The replacement of current chemical processing techniques with more environmentally benign alternatives is an increasingly attractive subject.[1]
The double-metal-modified Yb-Mo-HKSF catalyst was chosen as a base catalyst because it is the cheapest and most effective double-metal-modified montmorillonite catalyst in nitration of phenolic compounds[40] and impregnated it by various metal salts such as Mn(OAc)[2], FeCl3, CoCl2, NiCl2, CuCl2, ZnCl2, Cu(OAc)[2], Cu(NO3)[2], and CuSO4
We examined these metal salts impregnated Yb-Mo-HKSF41 catalysts
Summary
The replacement of current chemical processing techniques with more environmentally benign alternatives is an increasingly attractive subject.[1]. All these metal salts impregnated Yb-Mo-HKSF catalysts gave good results in the nitration of phenol and Of nitric acid.[40] Based on the above investigations, we turned out to use CuCl243 impregnated Yb-Mo-HKSF as a catalyst to nitrate a variety of other phenolic substrates with 1.2 equiv.
