Cotton farming sustainability: Formation of trans-isoeugenol/ bio-aromatics, 5-chloromethylfurfural, C13–C17 liquid hydrocarbons & fertilizer from cotton gin trash

A hemicellulose-first approach: one-step conversion of sugarcane bagasse to xylooligosaccharides over activated carbon modified with tandem plasma and acid treatments

“…S10† showed the 2D HSQC NMR spectra of bagasse and its residue after the hydrolysis reaction and the XOS from bagasse in different chemical shift regions, including the carbohydrate region ( δ C / δ H : 50–90/2.5–5.5 ppm), the carbohydrate anomeric region ( δ C / δ H : 90–110/4.0–5.5 ppm) and the lignin aromatic region ( δ C / δ H : 105–150/6.0–8.5 ppm). 54 In HSQC NMR analysis (semi-quantitative), there were no noticeable differences between the correlation peaks of carbohydrate and the lignin aromatic regions of bagasse and its residue. The HSQC NMR spectrum for the extracted XOS showed high intensities of the carbohydrate and carbohydrate anomeric regions, though low intensities of lignin aromatic regions were obtained, an indication of small loss of acid soluble lignin after hydrolysis.…”
