A process is provided for preparing ethyleneamines of the formula NH&#x2014;(CH&#x2014;NH&#x2014;)H wherein p is at least 3, or derivatives thereof wherein one or more units &#x2014;NH&#x2014;CH&#x2014;NH&#x2014; may be present as a cyclic ethylene urea unit or piperazine unit or between two units &#x2014;NH&#x2014;CH&#x2014;NH&#x2014; a carbonyl moiety is present. The process includes reacting an ethanolamine-functional compound OH&#x2014;(CH&#x2014;NH&#x2014;)H wherein q is at least 2, an amine-functional compound NH&#x2014;(CH&#x2014;NH&#x2014;)H 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.

Process to prepare ethylene amines and ethylene amine derivatives

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&#x2014;(C2H4-NH-)qH, q is at least 1, the amine-functional compound is of the formula H2N&#x2014;(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.

Process for making higher ethylene amines

A process for preparing hydroxyethyl ethylene amines and/or ethylene urea derivatives thereof includes reacting monoethylene glycol with an amine-functional compound having at least two &#x2014;NH&#x2014; units, of which at least one is selected from the group of primary amine groups and cyclic secondary amine groups, in the presence of a carbon oxide-delivering agent. The amine-functional compound includes at least one &#x2014;NH&#x2014;CH2-CH2-NH&#x2014; unit, wherein one or more &#x2014;NH&#x2014;CH2-CH2-NH&#x2014; units in the amine-functional compound may be present in the form of piperazine moieties or ethylene urea moieties. The molar ratio of amine-functional compound to monoethylene glycol is in the range of 0.2:1 to 1.5:1 and the molar ratio of carbon oxide-delivering agent to &#x2014;NH&#x2014;CH2-CH2-NH&#x2014; units in the amine-functional compound is at least 0.5:1. The process allows the conversion of monoethylene glycol into ethanol amines in the absence of metals-containing catalysts and without using ammonia.

Process for manufacturing hydroxyethyl ethylene amines

A process for preparing polyethyleneamines of formula NH2-(CH2-CH2-NH-)pH wherein p is at least 3 and wherein one or more &#x2014;NH-CH2-CH2-NH&#x2014; units may be piperazine units and/or ethylene urea derivatives of these compounds, includes reacting monoethylene glycol with an amine-functional compound having at least two &#x2014;NH&#x2014; units, of which at least one is selected from primary amine groups and cyclic secondary amine groups, in the presence of a carbon oxide-delivering agent. The amine-functional compound includes at least one &#x2014;NH-CH2-CH2-NH&#x2014; unit, and one or more &#x2014;NH-CH2-CH2-NH&#x2014; units may be in the form of cyclic ethylene urea moieties, piperazine moieties, or linear ethylene urea moieties. The molar ratio of amine-functional compound to monoethylene glycol is above 1.2:1 and the molar ratio of carbon oxide delivering agent to &#x2014;NH-CH2-CH2-NH&#x2014; units is at least 0.5:1. The process makes it possible to obtain ethylene amines and derivatives thereof without using ammonia or metal-containing catalysts.
