Abstract:
A liquid chromatography process for the purification of furfural derivative(s), comprising: a. Introducing a feed mixture comprising at least one furfural derivative and other compounds onto a chromatographic bed comprising a silicate-based material as stationary phase, and b. Flushing a liquid comprising an organic acid as mobile phase through the chromatographic bed producing an eluate comprising at least one fraction enriched in at least one furfural derivative and at least one fraction enriched in the other compounds.
