Samples of D-arabinose (Fisher Scientific), L-fucose (Acros), and D-xylose (Sigma Aldrich) were flash-pyrolyzed (Pyroprobe 5200, CDS) at 250°C and 350°C. Product gases were analyzed by two-dimensional gas chromatography with time-of-flight mass spectrometry (Pegasus 4D, LECO).
The yield of furan compounds in pyrolysis of D-xylose was more than from pyrolysis of L-fucose. Isomerization of D-arabinose to xylose was observed in arabinose pyrolysis. The dominant products in D-arabinose and D-xylose pyrolyses were water and glycolaldehyde. In the presentation we will discuss the possible mechanisms.
