Process for recovering .alpha.-aminoalcohols by extraction from aqueous solutions, in which process an aromatic aldehyde is added at elevated pH to an aqueous solution of an aminoalcohol in an at least equimolar amount in respect of the aminoalcohol, the resulting mixture is converted with formation of the Schiff base of the aldehyde and the aminoalcohol and the aqueous solution is subsequently extracted using a water-immiscible organic solvent, upon which the Schiff base in the resulting extract is hydrolized and the .alpha.-aminoalcohol or a salt thereof is recovered.
