    • The present invention relates to a process for preparing N,N-substituted 3-aminopropan-1-ols by a) reacting secondary amine with acrolein at a temperature of (−50) to 100° C. and a pressure of 0.01 to 300 bar, and b) reacting the reaction mixture obtained in stage a) with hydrogen and ammonia in the presence of a hydrogenation catalyst at a pressure of 1 to 400 bar, wherein the molar ratio of secondary amine to acrolein in stage a) is 1:1 or more and the temperature in stage b) is in the range from (−50) to 70° C. In a preferred embodiment, acrolein which has been obtained from glycerol based on renewable raw materials is used. The invention further relates to the use of an N,N-dimethyl-3-aminopropan-1-ol (DMAPOL) based on renewable raw materials as a catalyst for polyurethane preparation, as a scrubbing fluid in gas scrubbing, in the electronics chemicals and electroplating sectors, as a feedstock in organic synthesis, and as an intermediate in the production of pharmaceuticals and crop protection compositions.
    • 本发明涉及一种通过以下步骤制备N,N-取代的3-氨基丙-1-醇的方法:a)在(-50)至100℃的温度和0.01至300巴的压力下使仲胺与丙烯醛反应 ,和b)在加氢催化剂存在下,在1至400巴的压力下,将a)中获得的反应混合物与氢气和氨反应,其中a)步中仲胺与丙烯醛的摩尔比为1:1 或更高,步骤b)中的温度在(-50)至70℃的范围内。在优选的实施方案中,使用了基于可再生原料从甘油获得的丙烯醛。 本发明还涉及使用基于可再生原料的N,N-二甲基-3-氨基丙-1-醇(DMAPOL)作为聚氨酯制备的催化剂,在电气化学品中用作气体洗涤中的洗涤液, 电镀部门,作为有机合成中的原料,以及作为药物和作物保护组合物生产中的中间体。

    • The present invention relates to a process for preparing N,N-substituted 1,3-propanediamine by a) reacting secondary amine with acrolein at a temperature of from (−50) to 100° C. and a pressure of from 0.01 to 300 bar, and b) reacting the reaction mixture obtained in stage a) with hydrogen and ammonia in the presence of a hydrogenation catalyst at a temperature of from 40 to 400° C. and a pressure of from 1 to 400 bar, wherein the molar ratio of secondary amine to acrolein in stage a) is 2:1 or more and the hydrogenation catalyst used in stage b) comprises cobalt. In a preferred embodiment, acrolein which has been obtained from glycerol based on renewable raw materials is used. The invention further relates to the use of N,N-dimethyl-1,3-propanediamine (DMAPA) based on renewable raw materials as a feedstock for lubricant soaps and other detergents, coagulants, polymers and comb polymers. In a further preferred embodiment, stage b) is performed in the presence of water.
    • 本发明涉及一种通过以下步骤制备N,N-取代的1,3-丙二胺的方法:a)在(-50)至100℃的温度和0.01至300巴的压力下使仲胺与丙烯醛反应 和b)在加氢催化剂存在下,在40〜400℃,压力为1〜400巴下,使a)中获得的反应混合物与氢气和氨反应,其中摩尔比 阶段a)中的仲胺与丙烯醛的比例为2:1或更高,而阶段b)中使用的氢化催化剂包括钴。 在优选的实施方式中,使用从基于可再生原料的甘油获得的丙烯醛。 本发明还涉及基于可再生原料的N,N-二甲基-1,3-丙二胺(DMAPA)作为润滑剂皂和其它洗涤剂,凝结剂,聚合物和梳状聚合物的原料的用途。 在另一优选实施方案中,步骤b)在水的存在下进行。
