WebMORE In commercial production, hexanediamine （HDA） is derived from the hydrogenation （reduction） of adiponitrile （ADN）, which is mainly produced from butadiene （BD）. According to synthesis methodology, the BD based preparation of ADN and/or HDA can be classified into four methods, i.e., direct catalytic hydrocyanation of BD to ... WebWhat is claimed is: 1.
