ABSTRACT:
This invention is directed to novel phosphorus-free catalyst compositions based on titania pellets on which a minor amount of a tungstosilicic acid or a molybdosilicic acid is deposited. Also, the invention is directed to a process for preparing predominantly linear polyethylenepolyamines from ethylenediamine and monoethanolamine using the novel catalyst compositions.
