Recent approaches to furfural synthesis from hemicellulosic biomass and pentose sugars with both homogeneous and solid acidic catalysts have been summarized by addressing the associated sustainability issues. The features of deconstruction of hemicellulosic biomass by acid hydrolysis to produce pentose sugar feedstock for furfural have been discussed in brief. Several strategies including solvent extraction in a biphasic process, application of surface functionalized materials such as acidic resins, mesoporous solids and mechanistic insight in limited cases are discussed. The present status of the promising furfural platform in producing second generation biofuels (furanics and hydrocarbon) is reviewed. The performances of each catalytic system are assessed in terms of intrinsic reactivity and selectivity toward furfural production. Overall, this minireview attempts to highlight the scope of further developments for a sustainable furfural process and upgrading to fuels.

    ABSTRACT: Recently, furfural, “the sleeping beauty bio-renewable chemical” has gained a renewed attention as a potential chemical for the production of biofuels and biochemicals. Furfural is the most commonly produced industrial chemical because its production is very flexible. It is one of the top value-added chemicals that can be produced from biomass. Furfural and its derivatives have been extensively used in plastics, pharmaceutical and agrochemical industries. Furfural is a natural precursor to a range of furan-based chemicals and solvents such as dihydropyran, methyltetrahydrofuran, tetrahydrofuran, methylfuranfurfuryl alcohol, tetrahydrofurfuryl alcohol and furoic acid. Furfural and its derivatives have been widely applied as fungicides and nematicides, transportation fuels, gasoline additives, lubricants, resins, decolorizing agents, jet fuel blend stocks, drugs, insecticides, bio-plastics, flavor enhancers for food and drinks, rapid all-weather repair system for bomb-damaged runways and pot holes and also for wood modification and book preservation.

    • "An experimental design of factorial 2 4À1 was carried out to optimize hydrolysis conditions (Table S2). The limits for hydrolysis conditions, especially the temperature below 100 °C, were chosen to restrict the xylose dehydration into furfural as described in recent reviews [25] [30] [32] [41] [42]. "

    ABSTRACT: The purpose of this study is to target well-defined xylooligosaccharides by controlled sulfuric acidic hydrolysis of beechwood xylans. Parameters such as sulfuric acid and xylan concentrations, hydrolysis duration and temperature have been investigated, allowing optimum conditions to be determined (0.7 M H2SO4, 90 °C, 45 min). The obtained xylooligosaccharides show a well-defined structure and have been characterized using several techniques such as 1D and 2D nuclear magnetic resonance spectrometry and matrix-assisted laser desorption/ionization-time of flight mass spectrometry. This work demonstrated that mild acidic hydrolysis conditions enable the reproducible production of xylooligosaccharides containing, on average, six xylose units and only one 4-O-methyl-D-glucuronic acid unit likely positioned at the non-reductive chain-end.

    • "The study of copolymers containing oligosaccharides or polysaccharides has raised a growing interest since the early 1980s up to now ( Otsuka et al. 2012 ) because of the biocompatibility and biological activity of saccharides. The hydrolysis of xylans into sugars, furfural, or oligomers are one way for their utilization ( V á zquez et al. 2000 ; Moure et al. 2006 ; Gull ó n et al. 2010 ; M ä ki- Arvela et al. 2011 ; Dutta et al. 2012 ). The acidic hydrolysis of xylans under mild condition leads to well-defined xylooligosaccharides (XOS) with an aldehyde group at the reductive chain-end ( Christakopoulos et al. 2003 ; Akpinar et al. 2009, 2010; Chemin et al. 2015 ).
