  • Publication number: 20120123165
    Abstract: The instant invention provides cycloaliphatic diamines and a method of making the same. The cycloaliphatic diamines according to the instant invention comprise the reaction product of one or more cycloaliphatic cyanoaldehydes selected from the group consisting of 1,3-cyanocyclohexane carboxaldehyde, 1,4-cyanocyclohexane carboxaldehyde, mixtures thereof, and combinations thereof, hydrogen, and ammonia fed into a continuous reductive amination reactor system; wherein the one or more cycloaliphatic cyanoaldehydes, hydrogen, and ammonia are contacted 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; and wherein one or more cycloaliphatic diamines are formed; and wherein said one or more cycloaliphatic diamines are selected from the group consisting of 1,3-bis(aminomethyl)cyclohexane, 1,4-bis(aminomethyl)cyclohexane, combinations thereof, and mixtures thereof.

  • Publication number: 20120116124
    Abstract: 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.

  • Publication number: 20120116122
    Abstract: 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.

  • Publication number: 20120116123
    Abstract: The instant invention provides a process for separating one or more aliphatic diamines from reductive amination reaction solvents and impurities, and aliphatic diamines obtained via such a process. The process for separating one or more aliphatic diamines from reductive amination reaction solvents and impurities according to the instant invention comprises the steps of: (1) feeding one or more cycloaliphatic cyanoaldehydes, hydrogen, ammonia, and optionally one or more solvents into a continuous reductive amination reactor system; (2) contacting said one or more cycloaliphatic cyanoaldehydes, 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.
