ABSTRACT:
A method for the separation of primary amines such as bis-(2-aminoethyl)ether from tertiary amines such as N-(2-methoxyethyl)morpholine which have close boiling points via extraction using a non-polar hydrocarbon solvent is described. Alternatively, a polyhydroxylic compound or a mixture of such compounds may be added to a stream containing both bis-(2-aminoethyl)ether and N-(2-methoxyethyl)morpholine before extraction with the non-polar hydrocarbon is performed. The N-(2-methoxyethyl)morpholine is selectively removed by the hydrocarbon.
