  • Publication number: 20150057467
    Abstract: Process to prepare ethylene amines by the amination of ethylene oxide, ethylene glycol or ethanolamine in the presence of a catalyst, including a step wherein methylamine and ethylamine are removed from the reaction effluents, wherein the methylamine and the ethylamine are adsorbed onto or absorbed by absorbents and adsorbents (absorption/adsorption) and wherein the absorption/adsorption takes place in the liquid phase or in the gas phase.

  • Patent number: 7053247
    Abstract: 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.
