processo para a aminação direta altamente seletica, catalisada homogeneamente de álcoois primários com amoníaco para aminas primárias com alta proporção de volume da fase líquida para a gasosa e/ou altas pressões

摘要

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