    摘要: In the production of amines from nitriles where the nitriles are hydrogenated under pressure in the presence of a Raney Nickel Catalyst using hydrogen produced from methane and containing CO.sub.2, a more efficient separation of the product hexamethylene diamine from the catalyst is obtained by maintaining a specified carbonate concentration. This specific carbonate concentration improves the settling characteristics of the catalyst and reduces catalyst carryover into the crude hexamethylene diamine during decantation.
