173-P-US02410 PRODUCTION OF HIGHER AMINES BY THE GAS PHASE HYDROGENATION OF NITRILES ABSTRACT OF THE DISCLOSURE This invention relates to an improvement in a process for preparing lower acyclic saturated amines by the gas phase hydrogenation of nitriles. To carry out the gas phase hydrogena- tion, the temperatures utilized in the reaction zone are from about 150 to 250°C, the pressure from about atmospheric to 500 psia, and the space velocity from about 500-12,000. Preferably, the conditions are controlled such that the components in the reaction zone are not exposed to a temperature greater than 380°C for a period of time in excess of 0.03 seconds.
