The utility model provides a magnetic stabilization reaction device, which comprises a first heating device and a second tubular reactor which are sequentially connected; at least two Helmholtz coils which are axially arranged are arranged outside the second tubular reactor; the magnetically stabilized bed has the advantages of small axial mixed flow, easy separation of catalyst and low bed pressure drop, and the magnetically stabilized reaction device is applied to the reaction of preparing hexamethylene diamine by directly hydrogenating 6-aminocapronitrile, so that the reaction selectivity and the reaction efficiency are improved. |
