PROCESS TO PREPARE ETHYLENE AMINES AND ETHYLENE AMINE DERIVATIVES

The present invention relates to a process to prepare ethyleneamines of the formula NH2-(C2H4-NH-)PI-I 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...

More Information
Summary:The present invention relates to a process to prepare ethyleneamines of the formula NH2-(C2H4-NH-)PI-I 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, by 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 between 0.05:1 and 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 is not the process of reacting 3 moles ethylenediamine (EDA) and 1 mole AEEA (aminoethylethanolamine) in the presence of 1.65 moles of urea at 280 deg C for 2 hours. 本发明涉及制
