Is there a selective adsorbent that might remove higher alcohols from ethanol?

10 September 2018 1 7K Report

The adsorbent would need to remove C3-C5 alcohol from C2. There is also water present - much more than higher alcohols. The adsorbent would need to be hydrophobic. Any other suggestion for the separation would be welcome.

Carlos Araújo Queiroz

Charcoal and hard soda soap were suggested as adsorbents; cf.:Article Fusel oil: Composition, removal and potential utilization

Coconut shell charcoal sorbent is used for gas chromatography in NIOSH methods 1402 and 1405.
