The present disclosure pertains to a process for manufacturing alkyleneamine compounds, comprising the steps of wherein A is selected from the group of C2 to C4 alkylene units, optionally substituted by one or more C1 to C3 alkyl groups, with an alkylhalide compound to form an alkyleneamine hydrohalide salt comprising at least one cyclic alkyleneurea group of formula I, the alkylhalide compound being selected from the group of haloalkanes with 2-6 halogen atoms, and haloaminoalkanes, and

Process for manufacturing alkyleneamine compounds

The present disclosure pertains to a process for preparing hydroxyethylethyleneamines, ethyleneamines, or mixtures thereof, and/or ethylene urea derivatives thereof. The process includes reacting diethanolamine with an amine-functional compound that includes 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. 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 cyclic ethylene urea moieties, piperazine moieties, or linear ethylene urea moieties, in the presence of a carbon oxide delivering agent.

Process for manufacturing chain-extended hydroxyethylethyleneamines, ethyleneamines, or mixtures thereof

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.
