ABSTRACT:
There is described a process for the preparation of amines of the type RNH.sub.2, wherein R represents a hydrocarbon radical containing up to 18 carbon atoms, in particular an aliphatic, arylaliphatic, cycloaliphatic or aromatic radical, the said process being characterized by the fact that an amide having the formula RCONH.sub.2, wherein R has the aforesaid meaning, is reacted, at a pH less than or equal to 7, firstly with gaseous chlorine, in the absence or in the presence of a diluent, and the N-chloroamide thus formed is subsequently reacted with an alkali hydroxide and/or an earth alkali hydroxide.
