    • The instant invention provides a process for reductive amination of aliphatic cyanoaldehydes to aliphatic diamines, and aliphatic diamines produced via such method. The process for reductive amination of aliphatic cyanoaldehydes to aliphatic diamines comprises the steps of: (1) providing a mixture of one or more cycloaliphatic cyanoaldehydes, optionally water, and optionally one or more solvents, wherein said one or more cycloaliphatic cyanoaldehydes are selected from the group consisting of 1,3-cyanocyclohexane carboxaldehyde, 1,4-cyanocyclohexane carboxaldehyde, mixtures thereof, and combinations thereof; (2) contacting said mixture with a metal carbonate based solid bed or a weak base anion exchange resin bed at a temperature in the range of 15 to 40° C. for a period of at least 1 minute or more, for example 5 minutes or more; (3) thereby treating said mixture, wherein said treated mixture has a pH in the range of 6 to 9; (4) feeding said treated mixture, hydrogen, and ammonia into a continuous reductive amination reactor system; (6) contacting said treated mixture, hydrogen, and ammonia with each other in the presence of one or more heterogeneous metal based catalyst systems at a temperature in the range of from 80° C. to about 160° C. and a pressure in the range of from 700 to 3500 psig; (7) thereby producing one or more cycloaliphatic diamines, wherein said one or more cycloaliphatic diamines are diamines selected from the group consisting of 1,3-bis(aminomethyl)cyclohexane, 1,4-bis(aminomethyl)cyclohexane, combinations thereof, and mixtures thereof.
    • 本发明提供了脂肪族氰醛还原胺化成脂肪族二胺的方法,以及通过这种方法制备的脂肪族二胺。 将脂族氰醛还原胺化成脂族二胺的方法包括以下步骤:(1)提供一种或多种脂环族氰醛,任选的水和任选的一种或多种溶剂的混合物,其中所述一种或多种脂环族氰醛选自 由1,3-氰基环己烷甲醛,1,4-氰基环己烷甲醛,其混合物及其组合组成的组; (2)使所述混合物与金属碳酸盐基固体床或弱碱性阴离子交换树脂床在15至40℃的温度下接触至少1分钟或更长的时间,例如5分钟,或 更多; (3),从而处理所述混合物,其中所述处理的混合物的pH在6至9的范围内; (4)将所述处理的混合物,氢气和氨进料到连续还原胺化反应器系统中; (6)在一种或多种非均相金属基催化剂体系的存在下,在80℃至约160℃的温度范围内使所述经处理的混合物,氢气和氨彼此接触,并且在 范围从700至3500psig; (7),从而产生一种或多种脂环族二胺,其中所述一种或多种脂环族二胺是选自1,3-双(氨基甲基)环己烷,1,4-双(氨基甲基)环己烷及其组合的二胺和 其混合物。

    • The instant invention is a process for the conversion of aliphatic cyclic amines to aliphatic diamines. The process for conversion of aliphatic cyclic amines to aliphatic diamines comprises the steps of: (1) selecting one or more cyclic amines; (2) contacting said one or more cyclic amines with ammonia and hydrogen, optionally water, and optionally one or more solvents in the presence of one or more heterogeneous metal based catalyst systems at a temperature in the range of from 120° C. to about 250° C. and a pressure in the range of from 700 to 3500 psig for a period in the range of at least one hour or more in one or more reactor systems; (3) forming a product mixture comprising one or more aliphatic diamine, optionally a portion of said one or more cyclic amines, optionally a portion of said ammonia, optionally a portion of said hydrogen, optionally water, and optionally a portion of said one or more solvents; (4) removing said product mixture from the reactor system; (5) removing at least a portion of said portion of ammonia, said portion of hydrogen, or mixture thereof from said product mixture via distillation; (6) removing at least a portion of said portion of water via distillation; (7) removing at least a portion of said portion of one or more optional solvents via distillation; (8) removing at least a portion of said portion of one or more cyclic amines; (9) thereby separating said one or more aliphatic diamines from said product mixture; and (10) thereby converting said one or more cyclic amines to one or more aliphatic diamines.
    • 本发明是将脂族环胺转化为脂族二胺的方法。 将脂族环胺转化为脂肪族二胺的方法包括以下步骤:(1)选择一种或多种环胺; (2)在一种或多种非均相金属基催化剂体系的存在下,在120℃至约20℃的温度下,使所述一种或多种环胺与氨和氢,任选的水,以及任选的一种或多种溶剂接触。 250℃,压力范围为700-300psig,在一个或多个反应器系统中至少1小时以上; (3)形成包含一种或多种脂族二胺,任选地一部分所述一种或多种环胺,任选地一部分所述氨,任选地一部分所述氢,任选的水,以及任选地一部分所述一种或多种 更多溶剂; (4)从反应器系统中除去所述产物混合物; (5)通过蒸馏从所述产物混合物中除去所述部分氨,所述部分氢或其混合物的至少一部分; (6)通过蒸馏除去所述部分水的至少一部分; (7)通过蒸馏除去一种或多种任选溶剂的所述部分的至少一部分; (8)除去一种或多种环胺的所述部分的至少一部分; (9),从而将所述一种或多种脂族二胺与所述产物混合物分离; 和(10),从而将所述一种或多种环胺转化为一种或多种脂族二胺。
