ABSTRACT:
Process for production of polyalkylene polyamines, preferably non-cyclic polyalkylene polyamines, by reforming of other polyalkylene polyamines. The reforming process is effected by reacting the polyalkylene polyamine starting material in the presence of a phosphate, preferably a boron phosphate, catalyst at elevated temperature and pressure and in the presence of sufficient water and sufficient catalyst, for a reaction period and under reaction conditions otherwise adapted to bring about the desired reforming reaction.
