PROCESS FOR THE PREPARATION OF 2,2'-OXYBIS [N,N-DIMETHYLETHANAMINE]

摘要

A process for the preparation of 2,2'-oxybis¢N,N-dimethylethanamine! by reaction of 2,2'oxybisethanamine, hydrogen and formaldehyde having a reduced percentage of water on conventional fixed-bed hydrogenation catalysts. The reactants, especially the amine and formaldehyde, are heated to a predetermined temperature separate from each other, and then mixed with each other in the presence of the fixed-bed catalyst.
