Abstract:
(EN) The present invention pertains to a gas separation membrane, the gas separation membrane having a support membrane and a separation function layer which is disposed on the support membrane and contains a crosslinked polyamide obtained by polycondensation of a polyfunctional amine and a polyfunctional acid halide, wherein the number A of terminal amino groups, the number B of terminal carboxy groups, and the number C of amide groups in the crosslinked polyamide satisfy (A+B)/C≤0.66.
(FR) La présente invention concerne une membrane de séparation de gaz, la membrane de séparation de gaz ayant une membrane de support et une couche de fonction de séparation qui est disposé sur la membrane de support et contient un polyamide réticulé obtenu par polycondensation d'une amine polyfonctionnelle et d'une halogénure d'acide polyfonctionnel, le nombre A de groupes amino terminaux, le nombre B de groupes carboxy terminaux et le nombre C de groupes amides dans le polyamide réticulé satisfont (A+B)/C ≤ 0,66.
(JA) 本発明は、支持膜と、前記支持膜上に設けられ、多官能性アミンと多官能性酸ハロゲン化物との重縮合により得られる架橋ポリアミドを含有する分離機能層と、を備え、前記架橋ポリアミドの末端アミノ基の数A、末端カルボキシ基の数B、アミド基の数Cが、(A+B)/C≦0.66を満たすガス分離膜に関する。
