Abstract (en)
[origin: WO9707108A1] The invention relates to a process for the selective separation of morpholine from an aqueous solution containing morpholine, N-methyl morpholine and N-methyl morpholine-N-oxide, in which (A) a quantity of the aqueous solution is taken through a cation exchanger capable of adsorbing morpholine until said exchanger can carry substantially no more morpholine and an eluate substantially free from morpholine but containing N-methyl morpholine and N-methyl morpholine-N-oxide is obtained, and (B) the cation exchanger charged with morpholine is regenerated and re-used in step (A).
