  • Method of separating primary amines from tertiary amines using non-polar hydrocarbon solvent and water
    Patent number: 4552958
    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 and water is described. The water 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.
