Catalytic process for the preparation of linear polyethylenepolyamines using a titania-supported phosphamine catalyst for the preparation of linear polyethylene polyamines

摘要

Novel catalysts are disclosed which are prepared by reacting a minor amount of phosphonitrillic chloride with titania to form an intermediate reaction product that is reacted with a diamine chelating agent to provide a catalyst that can be used effectively to catalyze the reaction of monoethanolamine with ethylenediamine.
