Title:
LAYERED FLUORINE-CONTAINING METAL-ORGANIC FRAMEWORK MATERIAL FOR ADSORBING AND SEPARATING ETHYNYL AND ETHYLENE, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/169763
Kind Code:
A1
Abstract:
A layered fluorine-containing metal-organic framework material for adsorbing and separating acetylene and ethylene. The structural general formula is ML 2A, M being a metal ion, L being a broken line type organic ligand, A being an inorganic fluorine-containing anion, and the metal ion M being at least one of Cu 2+, Fe 2+, Co 2+, Ni 2+, and Zn 2+. The broken line type organic ligand L is at least one of 4,4'-dipyridylsulfoxide and 4,4'-dipyridylsulfone, and the inorganic fluorine-containing anion A is at least one of SiF 6
2-, GeF 6
2-, ZrF 6
2-, SnF 6
2-, TiF 6
2-, NbOF 5
2-, WO 2F 4
2-, and MoO 2F 4
2-. The layered fluorine-containing metal-organic framework material can be prepared by adopting an interface diffusion method, a solvothermal method or a room-temperature stirring method. The layered fluorine-containing metal-organic framework material is used as an adsorbent and is in contact adsorption with a gas mixture containing acetylene and ethylene, and efficient separation of acetylene/ethylene can be realized at room temperature, low acetylene content and low acetylene partial pressure.
