How to primary amine a secondary amine directly to amination with ammonia

摘要

The object of this invention, being method in order to produce primary amine, this methodological process A) the solution of the secondary alcohol is not the vapor phase and to be the aforementioned method of including the fact that it prepares with the liquid phase, B) separation ammonia and/or at least it makes front diagnosis contact with one which discharges ammonia chemical compound and the homogeneous system catalyst, it is formed and, C) methodological process B) in with when, separates primary amine, this method capacity ratio of capacity of the capacity anti- vapor phase of the liquid phase to be 0.25 or more in methodological process B, and/Or vis-a-vis the hydroxyl basis in the secondary alcohol methodological process B) the ammonia in is characterized by being used at least at mol ratio of 5 to 1.
