The present disclosure relates to methods for separating at least one amine chosen from diamines and omega-aminoacids from a feed mixture using a simulated moving bed (SMB) adsorptive technology.

The present invention relates to a device for separating two immiscible phases and/or for extracting one phase with another phase (phase separation or extraction device), comprising at least one vessel for receiving the at least two phases, at least one pipe for supplying a fluid to the vessel, at least one pipe for discharging a fluid from the vessel, and at least one arrangement comprising a transparent disk for observing the separation operation or the extraction operation, wherein at least the side of the transparent disk that faces the phases to be separated or extracted consists of sapphire (sapphire glass) or mica (mica disk), and to the use of such a device in the preparation of di- and poly-amines of the diphenylmethane series.
