Preparation some acid-activated montmorillonites from Cu Chi clay and using as catalyst in one-pot conversion of benzaldehyde into benzonitrile

Abstract

Montmorillonite is a "green" solid catalyst and support used in many organic reactions.  In this paper, we have prepared some acid-activated montmorillonites from Cu Chi clay. Then, we determinated physical-chemical properties such as specific surface area, cation exchange capacity, X-ray diffraction, chemical composition and acidity of these samples. Finally, we chose the best from these montmorillonites and used as catalyst in the one-pot conversion of benzaldehyde into benzonitrile under solvent-free and microwave irradiation.
