ABSTRACT:
This invention is directed to novel catalyst compositions based on a pelleted group IVb transition metal oxide to which about 0.5 to about 7 wt. % of phosphorus is thermally chemically bonded by a novel process wherein the pellets are impregnated with a liquid water-soluble phosphorus compound containing phosphorus-oxygen bonds, thermally treated after removal of unabsorbed liquid for 0.5 to 5 hours at 100.degree.-150.degree. C. to chemically bond the recited amount of phosphorus to the pellets followed by calcination at 200.degree. to 900.degree. C. to stabilize the pellets. Also disclosed is a regenerative process for preparing predominantly linear polyethylenepolyamines from ethylenediamine and monoethanolamine using the novel catalyst compositions.
