Title:
GAS SEPARATION MEMBRANE, GAS SEPARATION MODULE, GAS SEPARATION DEVICE, GAS SEPARATION METHOD, GAS SEPARATION MEMBRANE COMPOSITION, AND GAS SEPARATION MEMBRANE PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/179396
Kind Code:
A1
Abstract:
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.
