摘要： Urea derivatives, methods for preparing ethylene amines, and methods of polymer manufacturing are provided. An exemplary method for preparing ethylene amines with n ethylene units and n+1 amine groups wherein n is at least 4, or urea derivatives of said ethylene amines, includes reacting an ethanolamine-functional compound, an amine-functional compound, and a carbon oxide delivering agent, wherein the ethanolamine-functional compound is of the formula HO—(C2H4—NH—)qH, q is at least 1, the amine-functional compound is of the formula H2N—(C2H4—NH—)rH, r is at least 1, the sum q+r is at least 4 and wherein optionally one or more of the ethanol-amine functional compound or amine-functional compound are at least partly used as their cyclic carbamate derivative, or linear or cyclic urea derivative.

摘要： A process is provided for preparing 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 piperazine unit or between two units —NH—C2H4—NH— a carbonyl moiety is present. The process includes reacting an ethanolamine-functional compound OH—(C2H4—NH—)qH wherein q is at least 2, an amine-functional compound NH2—(C2H4—NH—)rH wherein r is at least 1, in the presence of a carbon oxide delivering agent, wherein the molar ratio of ethanolamine-functional compound to amine-functional compound is from about 0.05:1 to about 0.7:1 and the molar ratio of carbon oxide delivering agent to amine-functional compound is higher than the molar ratio of ethanolamine-functional compound to amine-functional compound, provided that the process does not comprise reacting 3 moles of ethylenediamine (EDA) and 1 mole of AEEA (aminoethylethanolamine) in the presence of 1.65 moles of urea at 280 deg C. for 2 hours.
