Abstract:
(EN) Provided are: a gas separation membrane having excellent gas permeability and capable of sustainably expressing desired gas separation selectivity even when contacting a plasticizing component such as toluene; a gas separation module using the gas separation membrane; a gas separation device; and a gas separation method. Also provided is a polyimide compound suitable as a constituent material of the separation membrane. The gas separation membrane has a gas separation layer containing a polyimide compound having a pentafluorosulfanyl group as a constituent material, the gas separation module and the gas separation device are each provided with the gas separation membrane, and the gas separation method uses the gas separation membrane. The polyimide compound is a compound suitable for the gas separation membrane.
(FR) L'invention concerne : une membrane de séparation de gaz ayant une excellente perméabilité aux gaz et capable d'exprimer de manière durable une sélectivité de séparation de gaz souhaitée même lors de la mise en contact d'un composant plastifiant tel que le toluène; un module de séparation de gaz utilisant la membrane de séparation de gaz; un dispositif de séparation de gaz; et un procédé de séparation de gaz. L'invention concerne également un composé polyimide approprié en tant que matériau constitutif de la membrane de séparation. La membrane de séparation de gaz a une couche de séparation de gaz contenant un composé polyimide ayant un groupe pentafluorosulfanyle comme matériau constitutif, le module de séparation de gaz et le dispositif de séparation de gaz sont chacun pourvus de la membrane de séparation de gaz, et le procédé de séparation de gaz utilise la membrane de séparation de gaz. Le composé polyimide est un composé approprié pour la membrane de séparation de gaz.
(JA) 優れたガス透過性を有し、また、トルエン等の可塑化成分と接触しても所望のガス分離選択性を持続的に発現することができるガス分離膜、それを用いたガス分離モジュール、ガス分離装置及びガス分離方法を提供し、上記分離膜の構成材料として好適なポリイミド化合物を提供する。ガス分離膜は、ペンタフルオロスルファニル基を有するポリイミド化合物を構成材料として含むガス分離層を有し、ガス分離モジュール、及びガス分離装置は、ガス分離膜を備え、ガス分離方法はガス分離膜を用いる。ポリイミド化合物は、ガス分離膜に好適な化合物である。
