“…It was oven then dried for 3 h at temperature of 105 °C and ground to 1 mm mesh size. Furfural was obtained from prepared sugarcane bagasse by steam distillation according to Barbosa et al [ 16 ]. Accurately weighed pulverized SB (15 g) was poured in a round bottom flask (500 mL) containing 50% H 2 SO 4 (150 mL) and NaCl salt (5 g) and distilled for 40 min to obtain furfural (Scheme 1 ).…”

Novel 1,3-bis[(furan-2-yl) methylene]thiourea (BFMT) dye was synthesized from condensation reaction between sugarcane bagasse derived furfural and thiourea. The synthesized BFMT dye was characterized by physicochemical (melting point and CHN) and spectrometry (UV–Vis, FTIR, 1 H-NMR and 13 C-NMR) analyses. The synthesized BFMT dye was screened for its antimicrobial (antibiotic and antifungal) properties. BFMT dye was applied on wool and cotton fabrics. The functional properties of BFMT dyed fabrics (color value, color strength, fastness properties, antimicrobial activities, ultraviolet protection factor (UPF), and mechanical properties) were assessed. Chemical composition of synthesized BFMT dye was determined by CHN analyzer, while its structure was confirmed by FTIR and NMR spectrometry analyses. BFMT dye solution showed reddish brown complementary color with λ max 485 nm on UV–Visible spectrophotometer. The antibiotic property of the synthesized dye was moderate, while antifungal property was excellent on tested microorganisms. BFMT dyed wool and cotton fabrics displayed good mechanical properties, air permeability, water vapor permeability and wetability. Dyed fabrics possessed excellent exhaustion (> 80%), fastness properties, ultraviolet protection factor (UPF > 40) and fungal growth inhibition rate (> 70%).

“…First, C 5 polysaccharides present in biomass hemicellulose are hydrolyzed by mineral acids to produce monosaccharides, primarily xylose, which is then converted into furfural by an acid catalyzed dehydration (Machado et al 2016, Verma et al 2017. Furfural production from corn stalk, sugarcane bagasse and eucalyptus wood using varying concentrations of mineral acids has also been reported (Barbosa et al 2014). Several solvents, such as ionic liquids, organic solvents and supercritical fluids were investigated in the monophasic system, whereas water/organic solvent mixtures were tested in a biphasic system (Mariscal et al 2016).…”

Until recently, most of energy and industrially produced chemicals were derived from fossil fuelbased resources. This along with the continued depletion of finite fossil resources and their attributed adverse environmental impacts, alternatively sourced and more sustainable resources are being pursued as feedstock replacements. Thus, biomass has been identified as an alternate renewable and more sustainable resource as a means to reduce this sector's dependence on fossil fuel-based resources and to alleviate their environmental impacts. As such, lignocellulosic biomass has been further identified and demonstrated as an abundant renewable resource for the production of biofuels, platform chemicals, and their respective value-added products. This review article provides an overview of the techniques developed for the valorization of biomass in the production of platform chemicals within a biorefinery, and the status for commercialization.

“…Furfural is obtained from hemicellulose found in the most abundant lignocellulosic biomass via two-step pathways: (i) acidic hydrolysis of hemicellulose into D-xylose then (ii) dehydration of D-xylose into furfural. The dehydration of D-xylose can be achieved with either homogeneous catalysts such as inorganic mineral acids (H2SO4, HCl, H3PO4) [4] or heterogeneous systems like zeolite or heteropolyacids [2]. However, the task of developing an effective transformation of D-xylose to furfural remains quite challenging.…”

As an attempt to replacing petroleum-based chemicals with bio-based ones, synthesis of furfural from biomass-derived xylose attracts much attention in recent days. Conventionally, furfural from xylose has been produced via the utilization of highly corrosive, toxic, and environmentally unfriendly mineral acids such as sulfuric acid or hydrochloric acid. In this study, microwaveassisted biphasic reaction process in the presence of novel bio-based heterogeneous acid catalysts was developed for the eco-benign and effective synthesis of furfural from xylose. The microwave was irradiated for reaction acceleration and a biphasic system consisting of H2O : MIBK (1 : 2) was designed for continuous extraction of furfural into the organic phase in order to reduce the undesired side products formed by decomposition/condensation/oligomerization in the acidic aqueous phase. Moreover, sulfonated amorphous carbonaceous materials were prepared from wood powder, the most abundant lignocellulosic biomass. The prepared catalysts were characterized by FT-IR, XPS, BET, elemental analysis and they were used as bio-based heterogeneous acid catalysts for the dehydration of xylose into furfural more effectively. For further optimization, the effect of temperature, reaction time, water/organic solvent ratio, and substrate/catalyst ratio on the xylose conversion and furfural yield were investigated and 100% conversion of xylose and 74% yield of furfural was achieved within 5 h at 180 ℃. The bio-based heterogeneous acid catalysts could be used three times without any significant loss of activity. This greener protocol provides highly selective conversion of xylose to furfural as well as facile isolation of product and bio-based heterogeneous acid catalysts can alternate the environmentally-burdened mineral acids.
