A layered porous material for adsorbing and separating allylene and propylene, wherein the layered porous material has periodic intra-layer rhombic pore channels and inter-layer broken line type pore channels, is formed by metal ion M, inorganic anion A and organic ligand L by means of coordination bond and supramolecular interaction, and has a structural general formula of ML2A. The metal ion M is at least one of Fe2+, Co2+, Ni2+, Cu 2+, and Zn 2+. The inorganic anion A is at least one of TiF6 2-, GeF6 2-, NbOF5 -, ZrF6 2-, and SnF 6 2-. The structural formula of the organic ligand L is: (I), where R1-R8 are each independently selected from H, F, Cl, Br, I, CH3, NH2, OH, or COOH. The layered porous material is an adsorbent, and the adsorbent is in contact with a mixed gas containing allylene and propylene to selectively adsorb the allylene, thereby implementing the separation of the propylene and the allylene. |
