ABSTRACT:
In the recovery of ethylene amines from aqueous solutions by alcohol extraction the alcoholic extract is treated with carbon dioxide so as to convert the extracted amines into carbamates, which are then back extracted with water and recovered by conventional decarbonation and dehydration. The double extraction technique results in an aqueous concentrate of at least twice the original amine concentration.
