摘要

Process for direct animation of secondary alcohols with ammonia to form primary amines.The present invention relates to a process for the preparation of primary amines comprising the process steps (a) preparation of a solution of a secondary alcohol in a fluid phase, not gas, (b) contatau00e7u00e3o phase with ammonia free and / or with at least one compound that releases Mu00f4nia and a catalyst homogu00eanio and, if appropriate, (c) isolation of the primary amine formed in the process step (b),Caraccterizado by the fact that the proportion by volume of the liquid phase for the volume of a gaseous phase in the process step B is greater than or equal to 0.25 and / or that the ammonia in the process step (b) on the hydroxyl groups in the secondary alcohol is used in a molar ratio of at least 5 For 1.
