Waste reduction in amide synthesis by a continuous method based on recycling of the reaction mixture

Abstract

In this article, a new one pot synthesis of amides is demonstrated. Potential of the recovery and reuse strategy for waste reduction is examined. Finally, a new strategy is proposed where the whole reaction mixture containing the catalyst, the solvent (auxiliary) and the unreacted starting material is recovered by precipitating the product using ethanol and reused for the next cycle in a continuous operation protocol.
