Abstract
(EN)
A gas separation asymmetric membrane has a gas-permeable porous layer and a compact layer which has gas separation capability and which is formed on the porous layer. The gas separation asymmetric membrane is formed using a polyimide compound that has structural units represented by general formula (I) and at least one type of structural unit selected from structural units represented by formula (II) and structural units represented by formula (III). The viscosity, at 25˚C, of a solution in which the polyimide compound is dissolved at a concentration of 5 mass% in N-methylpyrrolidone is 2.2 to 22.0 mPa·sec. A gas separation module and gas separation method use the gas separation asymmetric membrane. A gas separation device uses the gas separation module. In the formulas, X1 is a group having the structure represented by formula (I-a) or (I-b).

La présente invention concerne une membrane asymétrique de séparation de gaz ayant une couche poreuse perméable aux gaz et une couche compacte qui a une capacité de séparation de gaz et qui est formée sur la couche poreuse. La membrane asymétrique de séparation de gaz est formée à l'aide d'un composé de polyimide qui a des unités structurales représentées par la formule générale (I) et au moins un type de motif structural choisi parmi des unités structurales représentées par la formule (II) et des unités structurales représentées par la formule (III). La viscosité, à 25 °C, d'une solution dans laquelle le composé de polyimide est dissous à une concentration de 5 % en masse dans de la N-méthylpyrrolidone est entre 2,2 et 22,0 mPa·s. Un module de séparation de gaz et un procédé de séparation de gaz utilisent la membrane asymétrique de séparation de gaz. Un dispositif de séparation de gaz utilise le module de séparation de gaz. Dans les formules, X1 est un groupe ayant la structure représentée par la formule (I-a) ou (I-b).
