Kinetic Separation of Butane Isomers Using a Formate Metal-Organic Framework.
n-butane (n-C4H10) and isobutane (i-C4H10) are important raw materials in chemical industry. The separation of the two hydrocarbon isomers via distillation is challenging and energy-consuming. Herein we report the adsorption behavior of a microporous cobalt formate framework [Co3(HCOO)6] for potential kinetic separation of butane isomers. Under ambient condition, [Co3(HCOO)6] shows near adsorption capacity for n-C4H10 (1.77 mmol g-1) and i-C4H10 (1.36 mmol g-1) with different adsorption kinetics. Study on the adsorption kinetics for butane indicates that the smaller isomer is adsorbed at a higher diffusion rate, resulting in a high kinetic selectivity of 193 for n-C4H10/i-C4H10 separation. Analyses of adsorption kinetics and breakthrough experiment have validated the separation potential of [Co3(HCOO)6] for butane purification.
期刊介绍：
ChemPlusChem is a peer-reviewed, general chemistry journal that brings readers the very best in multidisciplinary research centering on chemistry. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies.
Fully comprehensive in its scope, ChemPlusChem publishes articles covering new results from at least two different aspects (subfields) of chemistry or one of chemistry and one of another scientific discipline (one chemistry topic plus another one, hence the title ChemPlusChem). All suitable submissions undergo balanced peer review by experts in the field to ensure the highest quality, originality, relevance, significance, and validity.
