ACIDIC GAS SEPARATION MEMBRANE, ACIDIC GAS SEPARATION DEVICE, METHOD FOR PRODUCING ACIDIC GAS SEPARATION MEMBRANE, AND ACIDIC GAS SEPARATION METHOD

WIPO Patent Application WO/2021/039309

A1

An acidic gas separation membrane according to the present invention is selectively permeable to an acidic gas, while comprising a first porous layer and a resin composition layer that is formed on the first porous layer with use of a resin composition. The resin composition contains a modified polyamine that is obtained by introducing at least one of an acidic dissociation group and a salt thereof into a polyamine. The acidic dissociation group is at least one group that is selected from the group consisting of a carboxy group, a sulfonic acid group, an oxysulfonic acid group, a phosphoric acid group and an oxyphosphoric acid group; and the polyamine is at least one compound that is selected from the group consisting of a polyethylene imine, a polyallyl amine and a polyvinyl amine.
