摘要:
Ethylene amines are extracted from a solution containing at least 10 wt.% of NaCl and a maximum of 5 wt.% of NaOH using a water-miscible solvent with a boiling point below 105°C, which solvent is immiscible with an aqueous salt solution. Such extraction allows for an economically favourable process for the recovery of ethylene amines to be obtained that will cause no environmental problems.
