Physical behavior of cotton linter cellulose in TFA. a Dry cotton linter cellulose powder was suspended in TFA at − 20 °C and incubated for 15 h at that temperature. Samples were rapidly suspended by vortex mixing in five volumes of ethanol at ambient temperature (0 h) or heated to 55 °C for up to 5 h before addition of ethanol. b Appearance of cellulose in each of the treatments after several washes in 80% ethanol in water (v/v), and in water. c Weight fraction of TFA-soluble carbohydrate. Mole% of major monosaccharides xylose, glucose, and mannose were determined as alditol acetates by GC–MS [38, 55]
