Hybrid anion exchange membranes, method of their production and use, and dialytic-catalytic method for obtaining aromatic amines

Abstract

The subject of the application is hybrid anion exchange membranes and a method for their production and use in carrying out simultaneous dialytic-catalytic processes enabling the simultaneous reduction of aromatic nitro compounds (AZN) and the separation of reaction products, i.e. aromatic amines (AAr), as well as a dialytic-catalytic method for obtaining aromatic amines.A method for producing hybrid anion exchange membranes which in the first stage are formed in the form of an interpolymer consisting of a domain of a chlorosulfonated copolymer of styrene and divinylbenzene S-co-DWB or a copolymer of vinylbenzyl chloride and divinylbenzene VBC-co-DWB in accordance with a known method, characterized in that in the next stage the obtained interpolymer membranes containing domains of a chlorosulfonated copolymer of styrene and divinylbenzene S-co-DWB or a copolymer of vinylbenzyl chloride and divinylbenzene VBC-co-DWB are modified with donor amine groups and then structures of catalytically active Re forms in the form of nCzRe are immobilized in them.
