Process for the manufacture of diethylenetriamine and higher polyethylenepolyamines |
摘要 |
The invention relates to a process for the manufacture of diethylenetriamine and higher polyethylenepolyamines by a transamination of ethylenediamine. The transamination is performed at a temperature from 135° C. to 180° C. at a pressure from 5 Mpa to 40 Mpa in the presence of hydrogen and a particulate catalysts containing 26 to 65% by weight of nickel on an oxide carrier. A high conversion degree of ethylenediamine and a high selectivity to form acyclic polyethylenepolyamines, such as diethylenetriamine are obtained by the process. The formation of cyclic amine compounds, e.g. piperazine, is low.
