Separation of CH/CH/CH and CH/CO in a Nitrogen-Rich Copper-Based Microporous Metal-Organic Framework.

The purification of industrially valuable CH and CH from multicomponent mixtures represents a crucial process in the chemical industry. In this study, we present a copper-based metal-organic framework () built on a nitrogen-rich organic linker that is capable of separating CH/CH/CH and CH/CO mixtures, therefore producing highly pure CH and CH, respectively. exhibits favorable adsorption of CH and CH over CH and thus achieves one-step CH purification from CH/CH/CH ternary mixtures, as verified by multicomponent breakthrough measurements. In addition, it can also extract CH from CH/CO binary mixtures.
