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.

The process comprises contacting the nitration medium with nitric oxide under conditions such that the nitric oxide will react with the nitric acid to form nitrogen dioxide and water. Gaseous nitrogen dioxide is removed from the reaction medium and accordingly, the dissolved nitroaromatic present in the nitration medium separates to form an organic phase which then can be removed by decantation. Typically, one mole of nitric oxide is added to the nitration medium for every two moles of nitric acid present in said medium. Reaction conditions normally are from about 0.degree. to 90.degree. C.
