  • Process for manufacturing a cyclic urea adduct of an ethyleneamine compound
    Patent number: 11292769
    Abstract: Methods are provided for manufacturing a cyclic urea adduct of an ethyleneamine compound, the ethyleneamine compound being selected from the group of ethyleneamines and hydroxyethylethyleneamines and comprising at least one —NH—CH2-CH2-NH— moiety and at least two ethylene moieties, wherein the ethyleneamine compound is reacted with CO2 in the presence of an auxiliary compound selected from ethylenediamine (EDA), monoethanolamine (MEA) and mixtures thereof, the molar ratio of auxiliary compound to amine compound being at least 0.02:1. It has been found that the presence of an auxiliary compound selected from ethylenediamine (EDA), monoethanolamine (MEA) and mixtures thereof leads to a substantial increase of the reaction rate as compared to a process wherein the auxiliary compound is not present.

  • Process to prepare higher ethylene amines or urea derivatives thereof
    Patent number: 10800731
    Abstract: A process is provided for preparing ethylene amines of the formula NH2—(C2H4—NH—)pH wherein p is at least 2, or derivatives thereof wherein one or more units —NH—C2H4—NH— are present as a cyclic ethylene urea unit The process includes reacting an ethanolamine-functional compound OH—(C2H4—NH—)qH or HO—(C2H4—NH)q—C2H4—OH wherein q is at least 1, and an amine-functional compound NH2—(C2H4—NH—)rH wherein r is at least 1, in the presence of a carbon oxide delivering agent and water, with a molar ratio of water:carbon oxide delivering agent of from about 0.01:1 to about 2:1.
