    摘要： A catalytically active composition suitable for reacting ethylene diamine and monoethanolamine to form linear polyethylene polyamines, having a low content of cyclic by-­products, can be obtained by treating titania with a solution of phosphonitrilic chloride and an acid scavenging agent in a solvent under conditions to form titania containing an intermediate reaction product of said phosphonitrilic chloride with a portion of said titania, treating said intermediate reaction product with a solution of a diamine chelating agent and an acid scavenging agent in a solvent under conditions to form a final reaction product, and calcining said final reaction product to activate said final reaction product.

    摘要： Predominantly linear polyethylenepolyamines can be prepared by reacting ethylenediamine with monoethanolamine in the presence of a phosphorus/titania/zirconia catalyst.
    The catalysts are prepared by mixing solutions of a tetrasubstituted compound of titanium with a tetrasubstituted compound of zirconium, adding a hydrolysing agent to coprecipitate titania and zirconia, treating the coprecipitate with a compound of phosphorus to bond from 0.5 to 6 wt.% of phosphorus to the coprecipitate and then stabilizing the resultant catalyst by calcining it at 200 to 800°C. Alternatively, the catalyst can be dried at 20 to 150°C and stabilized by subsequent calcining at 200 to 900°C.
