Title:
PROCESS FOR MAKING HIGHER ETHYLENE AMINES
Document Type and Number:
Japanese Patent JP2023103227
Kind Code:
A
Abstract:
To provide a process of preparing higher ethylene amines in high yield and high selectivity, without using expensive or hazardous starting materials.SOLUTION: There is provided a process to prepare ethylene amines with n ethylene units and n+1 amine groups wherein n is at least 4, or urea derivatives of the ethylene amines, by 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 ethanolamine-functional compound or amine-functional compound are at least partly used as their cyclic carbamate derivative, or linear or cyclic urea derivative.SELECTED DRAWING: None
