ABSTRACT:
A process is disclosed for the extraction recovery of ethylene amines from an aqueous solution containing at least 10% by weight sodium chloride and not more than 5% by weight sodium hydroxide, the process comprised of mixing with said aqueous solution an extraction-effective amount of a polar organic solvent which is immiscible with an aqueous salt solution, miscible with water and having a boiling poing below about 105.degree. C. This mixture is allowed to form an organic phase and an aqueous salt solution phase. The organic phase, which contains at least a portion of the ethylene amines, is separated from the aqueous salt solution phase. The preferred polar organic solvent is n-propanol. The preferred temperature range for the process is between about 70.degree. C. and about 95.degree. C.
