D-14873 CONVERSION OF OXYGEN-CONTAINING POLYAMINES ABSTRACT OF THE DISCLOSURE Process for preparing polyalkylene polyamines by contacting an alkanolamine, such as, ethanolamine, and a reactive nitrogen-containing base which is ammonia or a primary or secondary amine, in a first reactor to produce an alkyleneamine, such as, ethylenediamine, and an aminoalkylalkanolamine, such as, aminoethylethanolamine, in the presence of a catalytically effective amount of an amination catalyst and at a temperature and pressure sufficient to form the alkyleneamine and aminoalkylalkanolamine. Then the alkyleneamine, aminoalkylalkanolamine, unreacted alkanolamine and unreacted nitrogen-containing base are reacted in a second reactor to produce the polyalkylene polyamines, such as, diethylenetriamine, in the presence of a catalytically effective amount of an amination catalyst, such as, a reductive amination catalyst or a phosphorus-containing catalyst, and at a temperature and pressure sufficient to form the polyalkylene polyamines. Preferably the phosphorus-containing catalyst is a Group IIIB metal acid phosphate. By controlling the relative amounts of the feed components, one can achieve a desired D-14873 molecular weight distribution and range in the polyalkylene polyamine product. The process has utility in the preparation of cyclic and noncyclic organic amines.
