Modified Mg–Al hydrotalcite: a highly active heterogeneous base catalyst for cyanoethylation of alcohols

Abstract

Modified Mg–Al hydrotalcite (Mg:Al = 3:1) prepared by thermal decarbonation followed by rehydration of a conventional Mg–Al hydrotalcite is found to be a highly active, reusable and air stable catalyst for cyanoethylation of alcohols.
