Abstract:
(EN) A gas separation membrane is provided which can achieve gas permeability and gas separation selectivity at a desired high level, and can further exhibit the excellent separation membrane performance mentioned above (gas permeability, gas separation selectivity) persistently, even in the presence of plasticizing impurities, a gas separation module using said gas separation membrane, a gas separation device, a gas separation method, a gas separation membrane composition, and a gas separation membrane production method are provided. This gas separation membrane has a polyimide compound that includes a structural unit represented by expression (1). In expression (1), Ra1 represents a parent nucleus of a specific structure. La represents an n+1 valent linking group, and n is an integer greater than or equal to 1. A represents a hydrophilic group other than an amino group, with the CLogP value of less than or equal to 0.5.
(FR) L'invention concerne une membrane de séparation de gaz qui peut obtenir une perméabilité aux gaz et une sélectivité de séparation de gaz à un niveau élevé souhaité, et peut en outre présenter l'excellente performance de membrane de séparation mentionnée ci-dessus (perméabilité aux gaz, sélectivité de séparation de gaz) de manière persistante, même en présence d'impuretés plastifiantes, un module de séparation de gaz utilisant ladite membrane de séparation de gaz, un dispositif de séparation de gaz, un procédé de séparation de gaz, une composition de membrane de séparation de gaz, et un procédé de production de membrane de séparation de gaz. Cette membrane de séparation de gaz comprend un composé de polyimide qui comprend une unité structurelle représentée par l'expression (1). Dans l'expression (1), Ra1 représente un noyau parent d'une structure spécifique. La représente un groupe de liaison de valence n+1, et n est un nombre entier supérieur ou égal à 1. A représente un groupe hydrophile autre qu'un groupe amino, la valeur CLogP étant inférieure ou égale à 0,5.
(JA) ガス透過性とガス分離選択性を所望の高いレベルで実現することができ、さらに可塑化不純物の存在下においても上記の優れた分離膜性能(ガス透過性、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、ガス分離方法、ガス分離膜用組成物、及び上記ガス分離膜の製造方法を提供する。ガス分離膜は、下記式(1)で表される構造単位を含むポリイミド化合物を有する。 式(1)中、Ra1は特定構造の母核を示す。Lは、n+1価の連結基を示し、nは1以上の整数である。Aはアミノ基以外の基であって、CLogP値が0.5以下の親水性基を示す。
