Abstract
Separation of mixtures of ethylamines is carried out by extracting a mixture comprising diethylamine, triethylamine, ethanol, water and optionally monoethylamine with water and a water-immiscible solvent, for example an alkane or aromatic hydrocarbon under such conditions that the ethanol and any monoethylamine are extracted into the water layer, the triethylamine into the water-immiscible layer, while the diethylamine is partitioned between the two layers, the diethylamine passing into either of the two layers when it forms a substantial component (greater than about 12%) of the ethylamine mixture but passing largely into the water layer when it forms a less significant part (up to about 11%) of the ethylamines mixture. <IMAGE>
