Abstract The separation and purification of acetylene from the light hydrocarbon gas mixtures is considered as one most industrially challenging task for production fine chemicals. Though metal–organic frameworks (MOFs) are promising candidates such offer a cost energy‐efficient pathway, achieving trade‐off between sorption capacity selectivity along with framework robustness daunting demands effective design. Herein, new 3D chemically stable MOF, IITKGP‐24 (stable over wide range aqueous pH solution, = 2–12) developed, displaying excellent 13.9 C 2 H /CO (50:50) even at ambient conditions maintained selectivity. Most importantly, breakthrough performance analysis under relevant mixture composition revealed that developed possesses not only but also quaternary /C 4 6 (25:25:25:25) feed streams. Separation four component by MOFs unexplored. exceptional robustness, high uptake ratio, low heat adsorption, recyclability easy regenerability made candidate toward this separation.
