Abstract
A találmány tárgya eljárás a megfelelő piperidin-4-onokbólelőállított, majd desztillációval izolált 2,2,6,6-tetraszubsztituált-4-amino-piperidinek tisztítására, amely szerint a desztillált 2,2,6,6-tetraszubsztituált-4-amino-piperidint valamilyen hidrogénező- vagydehidrogénezőkatalizátor jelenlétében hidrogénnel reagáltatják, és a4-amino-piperidint a reakcióelegyből kinyerik.
