PROCESS FOR HOMOGENEOUSLY CATALYZED, HIGHLY SELECTIVE DIRECT AMINATION OF PRIMARY ALCOHOLS WITH AMMONIA TO PRIMARY AMINES WITH A HIGH VOLUME RATIO OF LIQUID PHASE TO GAS PHASE AND/OR HIGH PRESSURES

摘要

The present invention provides a process for preparing primary amines, comprising the steps of A) providing a solution of a primary alcohol in a fluid, non-gaseous phase, B) contacting the phase with free ammonia and/or at least one ammonia-releasing compound and a homogeneous catalyst, and optionally C) isolating the primary amine formed in step B), characterized in that the volume ratio of the volume of the liquid phase to the volume of the gas phase in step B is greater than 0.05 and/or that step B is carried out at pressures greater than 10 bar.
