An improved synthesis process was developed for large-scale production of a highly porous material, denoted as Cu-BTC, where BTC denotes benzene-1,3,5-tricarboxylate. A series of sorption properties for nitrogen, oxygen, carbon monoxide, carbon dioxide, nitrous oxide, methane, ethylene, ethane, n-dodecane, and water were studied. A detailed investigation of sorption thermodynamics was performed for carbon dioxide by a sorption-isosteric method. The experimental results show that Cu-BTC can be used for separation of gas mixtures such as carbon dioxide-carbon monoxide, carbon dioxide-methane and ethylene-ethane mixtures. In addition, air can be purified effectively from carbon dioxide, nitrous oxide, high-molecular weight hydrocarbons and moisture.
