ABSTRACT:
A method is disclosed for separating alkyleneamines from a mixture of by-product alkali or alkaline earth metal chloride salt and alkyleneamines comprising the sequenced combination of the steps of: (a) washing said amine-chloride salt mixture with an aqueous alkali or alkaline earth metal hydroxide solution to form a washed amine-chloride salt mixture; and (b) treating a mixture of the amino and chloride salt to physically separate chloride salt from said amine of said mixture.
