MULTI-STEP PROCESS FOR CONVERTING CYCLIC ALKYLENE UREA TO THEIR CORRESPONDING ALKYLENE AMINES |
| abstract |
The invention relates to a process for converting a feedstock comprising cyclic alkylene ureas to their corresponding alkylene amines, the process comprising: a CO 2 removal step in which cyclic alkylene ureas are converted into their corresponding alkylene amines by reacting cyclic alkylene ureas in the liquid phase with water removing CO 2, an amine removing step in which cyclic alkylene ureas are converted in a reactive separation process into their corresponding alkylene amines by reaction with an amine compound selected from the group of primary amines or secondary amines which have a higher boiling point than the alkylene amines formed during the process. It has been discovered that the combination of a CO 2 removal step and an amine removal step enables the alkylene ureas to be converted to the corresponding amines in an efficient manner in a high reaction rate. |
