| titleOfInvention | Reductive aminolysis process |
| abstract | Ethylene diamines and heterocyclic nitrogen compounds are obtained by subjecting materials containing polyhydric alcohols to reductive aminolysis, by reacting them with hydrogen and ammonia or a primary or secondary amine, or a compound yielding the same under the reaction conditions, in the presence of a hydrogenation catalyst at 150-300 DEG C. and under a pressure of 750-15,000 p.s.i., at least 3 mols of the nitrogenous reactant being present for each 100 grams of polyhydric alcohol, and the hydrogenation catalyst being present in sufficient quantity to provide an initial rate of hydrogen absorption of at least one mole of hydrogen per hour per kilogram of polyhydric alcohol. Suitable polyhydric alcohols are mono-, di-and poly-saccharides, glycols, glycerol, erythritol, sorbitol and mannitol; crude and impure forms of these alcohols may be used, such as corn syrup, hydrol syrup, citrus molasses, sugar molasses, invert sugar solutions; finely divided potato, corn and other grains; sugar cane bagasse, bagasse pith, sugar beet pulp; corn stalks, corn cobs, straw, oat hulls and cottonseed hulls; hemicelluloses, lignins, bark and sawdust. Suitable amines include aliphatic amines, alkanolamines, polybasic amines, aralkylamines, cyclic amines, and aromatic amines. Compounds which produce amines under the reaction conditions include nitriles and amides. The products are piperazine and substituted piperazines and ethyl-enediamine and N-substituted ethylene diamines, with ethanolamine, dimethyl ethanolamine and 2-aminopropanol specified as by-products. Specification 449,474 is referred to. |
