Document Type and Number:
WIPO Patent Application WO/2021/157433
Kind Code:
A1
Abstract:
The present invention provides a separation membrane suitable for separating water from mixed liquid including alcohol and water. The separation membrane according to the present invention comprises a metal organic structure. The separation membrane satisfies at least one of the following conditions (i) and (ii). (i) The ratio R1 of the number of molecules N2 satisfying a predetermined condition (b) to the number of molecules N1 satisfying a predetermined condition (a) is less than 0.29. (ii) The ratio R2 of an adsorption amount of water onto the metal organic structure in water vapor at 25°C and 3.2 kPa to an adsorption amount of ethanol onto the metal organic structure in an ethanol atmosphere at 25°C and 7.4 kPa is more than 4.0.
