Abstract: The invention relates to a method for purifying 2,2,6,6-tetrasubstituted 4amino-piperidines produced from the corresponding piperidin-4-ones, and subsequent distillation. According to the invention, the distilled 2,2,6,6tetrasubstituted 4-amino-piperidine is reacted with hydrogen in the presence of a hydrating or dehydrating catalyst and the 4-amino piperidine is then separated from the reaction mixture.
