    摘要: The invention provides a process for preparing primary amines, comprising the steps of A) providing a solution of a secondary alcohol in a fluid, non-gaseous phase, B) contacting the phase with free ammonia and/or with at least one ammonia donor compound and a homogeneous catalyst, and optionally C) isolating the primary amine formed in step B), characterized in that the ratio of the volume of the liquid phase to the volume of the gas phase in step B)is greater than or equal to 0.25 and/or in that the ammonia in step B) is used in a molar ratio, relative to the hydroxyl groups in the secondary alcohol, of at least 5:1.
