    Description

    General description

    Furfural is a heterocyclic aldehyde. It can be produced from agricultural raw materials containing pentosans[6] and lignocellulosic feedstock.[1] 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:[5]
    • 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.[2] It may be used in the preparation of γ-valerolactone (GVL)[3] and biofuel 2-methylfuran (51% yield).[4]

    Furfural undergoes hydrogenation in the vapor-phase over copper-containing catalysts to form furfuryl alcohol as the predominant product.[8] It may also be used to prepare gel precursors for phenol-furfural aerogels.[9]
