From: Gas-phase pyrolysis of methyl glucosides and levoglucosan
1H-NMR spectrum of the DMSO-d 6-soluble portion obtained from the pyrolysis of gaseous methyl α-glucoside (GlcαOMe) at 500 °C with a residence time of 1.2 s under a N2 flow of 400 mL min−1. Filled squares levoglucosan (LG); open circles GlcαOMe; asterisks internal standard (2-furoic acid); acetaldehyde (AA); acetic acid (AcOH); formaldehyde (Fald); formic acid (FcOH); glycolaldehyde (GA); glyoxal (GO); methylglyoxal (MeGO)
