Naoh ftir spectrum
WitrynaIn aromatic compounds, each band in the spectrum can be assigned: C–H stretch from 3100-3000 cm -1 overtones, weak, from 2000-1665 cm -1 C–C stretch (in-ring) from 1600-1585 cm -1 C–C stretch (in-ring) from 1500-1400 cm -1 C–H "oop" from 900-675 cm -1 Note that this is at slightly higher frequency than is the –C–H stretch in alkanes. Witryna31 paź 2005 · Crystalline structures of cellulose (named as Cell 1), NaOH-treated cellulose (Cell 2), and subsequent CO2-treated cellulose (Cell 2-C) were analyzed by wide-angle X-ray diffraction and FTIR spectroscopy. Transformation from cellulose I to cellulose II was observed by X-ray diffraction for Cell 2 treated with 15-20 wt% NaOH.
