摘要: The present invention relates to a process to prepare ethyleneamines of the formula NH2—(C2H4—NH—)pH wherein p is at least 3 or derivatives thereof wherein one or more units —NH—C2H4—NH— may be present as a cyclic ethylene urea unit or between two units —NH—C2H4—NH— a carbonyl moiety is present, by reacting an ethanolamine-functional compound, an amine-functional compound in the presence of a carbon oxide delivering agent, wherein the molar ratio of ethanolamine-functional compound to amine-functional compound is at least 0.7:1 and the molar ratio of carbon oxide delivering agent to amine-functional compound is at least 0.05:1.

摘要: The present invention relates to a process to prepare ethyleneamines of the formula NH2—(C2H4—NH—)pH wherein p is at least 2 wherein one or more units —NH—C2H4—NH— are present as a piperazine unit or precursors thereof wherein optionally one or more units —NH—C2H4—NH— are present as a cyclic ethylene urea unit or between two units —NH—C2H4—NH— a carbonyl moiety is present, by reacting an ethanolamine-functional compound, an amine-functional compound in the presence of a carbon oxide delivering agent, wherein at least one of the amine-functional compound or the ethanolamine-functional compound contains a piperazine unit, and the reaction is performed in a liquid that comprises water.

摘要: The present invention relates to a process to convert cyclic alkylene ureas into their corresponding alkylene amines wherein the process is performed by reaction with an amine compound, and wherein the amine compound comprises a primary amine, a cyclic secondary amine or a tertiary bicyclic amine.
