Abstract

Procedimiento para la purificación de 4-amino-piperidinas2,2,6,6-tetrasustituidas, obtenidas a partir de las piperidin-4-onas correspondientes y destilación subsiguiente, procedimiento que está caracterizado porque la 4-amino-piperidina 2,2,6,6-tetrasusti-tuida, destilada se hace reaccionar, en presencia de un catalizador de hidrogenación o deshidrogenación, con hidrógeno, y la 4-amino-piperidina se separa de la mezcla de reacción. Procedimiento según la reivindicación 1 para la purificación von 4-amino-piperidinas de la fórmula I en la que R1 a R4 significan alquilo con 1 a 6 átomos de carbono, R1 y R2 y/o R3 y R4 forman juntos una cadena de CH2 con 2 a 5 átomos de carbono, obtenidas a partir de las piperidin-4-onas correspondientes de la fórmula II Procedimiento según la reivindicación 1 para la purificación von 4-amino-piperidinas de la fórmula I según la reivindicación 2, en la que R1 , R2 , R3 y R4 significan metilo. Procedimiento según las reivindicaciones 1 a 3, caracterizado porque man la reacción se realiza con hidrógeno a temperaturas de 20 a 200°C. Procedimiento según la reivindicación 1, caracterizado porque la reacción se realiza a presiones de 1 a 30 mPa.
