Lives up to the claims by the authors


This paper reports the synthesis of hexamethylenebisacetamide (HMBA) without organic solvent or gas protection via amide exchange reaction of hexamethylenediamine (HDA) with CH3CN and H2O catalysed by CuO. The authors report the method to be more efficient than...
