摘要: The present invention relates to an improvement in a process for preparing primary amines by hydrogenating nitrites. The improvement in the hydrogenation process is that a hydrogenation catalyst modified ex situ with preadsorbed alkali metal carbonate or hydrogencarbonate such as K2CO3 or KHCO3 is used.
