General description
Furfural is a heterocyclic aldehyde. It can be produced from agricultural raw materials containing pentosans[1] and lignocellulosic feedstock.[2] It is also obtained from xylose, via dehydration. Furan has various interesting properties, such as it thermosets easily, has physical strength and exhibits resistance to corrosion. It is a raw material for the production of various furan-based chemicals and solvents such as:[3] - methylfuran - furfuryl alcohol - tetrahydrofurfuryl alcohol - tetrahydrofuran - methyltetrahydrofuran - dihydropyran - furoic acid Application Furfural has been employed as a standard for the HPLC quantification of furfural in the autohydrolysate liquor obtained from microwave-irradiated maize bran.[4] It may be used in the preparation of γ-valerolactone (GVL)[5] and biofuel 2-methylfuran (51% yield).[6] Furfural undergoes hydrogenation in the vapor-phase over copper-containing catalysts to form furfuryl alcohol as the predominant product.[7] It may also be used to prepare gel precursors for phenol-furfural aerogels.[8] |
