ABSTRACT:
This invention relates to an improved process for the preparation of 3-aminopropanol and a primary amine by reacting a cyanoethyl ketoxime with hydrogen in the presence of a hydrogenation catalyst to generate the primary amine and aminopropanol. The sequence of reactions to form the aminopropanol and primary amine involves the reaction of hydroxylamine with a ketone to generate a ketoxime followed by reaction of acrylonitrile with the ketoxime to generate a cyanoethyl ketoxime followed by complete hydrogenation of the cyanoethyl ketoxime in the presence of a hydrogenation catalyst to generate the primary amine and aminopropanol. The significant advantage associated with this process is the high degree of selectivity to 3-aminopropanol and the primary amine.
