The present invention discloses a method for separating propylene, propyne, propane and propadiene from mixed gas, wherein, comprising: a high purity component can be obtained as metal-organic frameworks as adsorbents through adsorptive separation and purification of a mixed gas containing propylene, propyne, propane and propadiene a general structural formula of the metal-organic framework material is [M(C.sub.4O.sub.4)(H.sub.2O)].1.5H.sub.2O, wherein M is metal ions, the metal-organic framework material is a three-dimensional network structure formed by transition metal ions or alkaline earth metal ions and squaric acid through coordination bonds or intermolecular forces. The metal-organic framework materials of the present invention exhibit excellent adsorption and separation performances for propylene, propyne, propane and propadiene. The cheap and available raw materials for the synthesis, simple operation, and low cost make it cost-efficient for preparation of such metal-organic frameworks. Besides, the good regeneration and repeatability, the adsorption performances kept intact with that of the original one after being activated under vacuum for several times, indicating that they have a great promising and potential for industrial application.
