Preparation of linear polyethylenepolyamines by reacting monoethanolamine with ethylenediamine in the presence of a phosphorus/titania/zirconia catalyst |
| abstract |
This invention relates to a method for the preparation of predominantly linear polyethylenepolyamines by reacting ethylenediamine with monoethanolamine in the presence of a phosphorus/titania/zirconia catalyst. The catalysts that are used in accordance with the present invention are composed of phosphorus, titania and zirconia. They are prepared by mixing solutions of a tetravalent compound of titanium with a tetravalent compound of zirconium, treating the solution to simultaneously heterogeneously coprecipitate titania and zirconia to form a heterogeneous titania/zirconia support, recovering the coprecipitate, treating it with a compound of phosphorus to bond from about 0.5 to 6 wt. % of phosphorus to the coprecipitate and then stabilizing the resultant catalyst by calcining it at about 200° to about 800°C. |
