Abstract:
The present invention relates to a process to prepare ethyleneamines of the formula NH 2 —(C 2 H 4 —NH—) p H wherein p is at least 2 wherein one or more units —NH—C 2 H 4 —NH— are present as a piperazine unit or precursors thereof wherein optionally one or more units —NH—C 2 H 4 —NH— are present as a cyclic ethylene urea unit or between two units —NH—C 2 H 4 —NH— a carbonyl moiety is present, by reacting an ethanolamine-functional compound, an amine-functional compound in the presence of a carbon oxide delivering agent, wherein at least one of the amine-functional compound or the ethanolamine-functional compound contains a piperazine unit, and the reaction is performed in a liquid that comprises water.

Claim (Index 1):
Process to prepare ethyleneamines of the formula NH 2 \u2014(C 2 H 4 \u2014NH\u2014) p H wherein p is at least 2 wherein one or more units \u2014NH\u2014C 2 H 4 \u2014NH\u2014 are present as a piperazine unit or precursors thereof wherein optionally one or more units \u2014NH\u2014C 2 H 4 \u2014NH\u2014 are present as a cyclic ethylene urea unit or between two units \u2014NH\u2014C 2 H 4 \u2014NH\u2014 a carbonyl moiety is present, by reacting an ethanolamine-functional compound, an amine-functional compound in the presence of a carbon oxide delivering agent, in which;\n the ethanolamine functional compound contains a hydroxyl group linked via an ethylene group to an amine group, or its carbamate equivalent or cyclic carbamate equivalent, or the ethanolamine functional compound is UAEEA (the urea of aminoethylethanolamine); \n the amine functional compound contains no alcohol groups, and contains one or more amine groups, or the amine functional compound is the cyclic urea of ethylenediamine (EU); \n the carbon oxide delivering agent is carbon dioxide or an organic compound selected from urea, linear and cyclic alkylene ureas, mono- or di-substituted alkylene ureas, alkyl and dialkyl ureas, linear and cyclic carbamates and organic carbonates, and derivatives or precursors thereof selected from carbonate salts, bicarbonate salts and carbamic acids and their salts; \n wherein at least one of the amine-functional compound or the ethanolamine-functional compound contains a piperazine unit, and the reaction is performed in a liquid that comprises water.
