Abstract
Procedimiento para la purificación de piperidinas de lafórmula I: en la que R1 hasta 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 hasta 5 átomos de carbono, caracterizado porque en una primera etapa se separan sustancias de alto punto de ebullición y eventualmente agua de las piperidinas crudas por destilación, en una segunda etapa se agrega 0,01 hasta 5% en peso, con respecto al producto de la primera etapa, de un agente de reducción, y en una tercera etapa se aíslan las piperidinas por destilación.
