EFFECT OF THE EXCHANGED CATION IN AN ALGERIAN MONTMORILLONITE USED AS A HETEROGENEOUS CATALYST FOR BIGINELLI REACTION

Effect of the Exchanged Cation in an Algerian Montmorillonite Used as a Heterogeneous Catalyst for Biginelli Reaction

In this work, an Algerian montmorillonite (Mt) is exchanged by different cations from the transition metals family, namely: Cu2+, Ni2+, Cr3+, Co2+, Fe2+ and Fe3+, it is used as a heterogeneous catalyst for Biginelli reaction.The exchanged cations are known for their catalytic properties in homogeneous catalysis.The main purpose is to study the effe
