    • Two alternative methods for producing at least one N-substituted acyclic ethylene diamine are provided:
      Method A according to the invention comprises:
      - reacting at least one reducing sugar, hydrogen and at least one primary amine NH 2 R or at least one secondary amine NHR'R" or a mixture of at least one primary amine NH 2 R and at least one secondary amine NHR'R"
      - in the presence of a supported hydrogenation catalyst
      - at a reaction temperature of 50°C to 200 °C, and
      - at a reaction pressure being superatmospheric pressure, and wherein
      - the molar ratio of the at least one primary amine and/or secondary amine : reducing sugar is at least 4:1.
      Method B according to the invention comprises the steps:
      1. reacting at least one reducing sugar and at least one primary amine NH 2 R or at least one secondary amine NH 2 R'R" or a mixture of at least one primary amine NH 2 R and at least one secondary amine NHR'R" in a first step, and
      2. reacting the reaction mixture obtained in step 1) with hydrogen in the presence of a supported hydrogenation catalyst in a second step.
    • 提供了两种制备至少一种N-取代的无环乙二胺的替代方法:根据本发明的方法A包括: - 使至少一种还原糖,氢和至少一种伯胺NH 2 R或至少一种仲胺NHR'R “或至少一种伯胺NH 2 R和至少一种仲胺NHR'R” - 在负载型加氢催化剂存在下的混合物 - 在50℃至200℃的反应温度下,和 - 在反应压力 为超计大气压,并且其中 - 所述至少一种伯胺和/或仲胺:还原糖的摩尔比为至少4:1。 根据本发明的方法B包括以下步骤:1.使至少一种还原糖与至少一种伯胺NH 2 R或至少一种仲胺NH 2 R'R“或至少一种伯胺NH 2 R与至少一种仲胺 胺NHR'R“,和2.在步骤1)中获得的反应混合物与氢气在负载型加氢催化剂的存在下在第二步中反应。
