Yield of 1,6-anhydro-3,4-dideoxy-β-D-glycero-hex-3-enopyranos-2-ulose (levoglucosenone) on the acid-catalyzed pyrolysis of cellulose and 1,6-anhydro-β-D-glucopyranose (levoglucosan)

Although 1,6-anhydro-3,4-dideoxy-β-D-glycero-hex-3-enopyranos-2-ulose (2) is produced by the acid-catalyzed pyrolysis of both cellulose and 1,6-anhydro-β-D-glucopyranose (1), data presented here show that the principal mechanism of its formation in the pyrolysis of cellulose is not via 1. Furthermore, the data provide evidence that 1 itself is not...

Speculations on the nature of cellulose pyrolysis

Consideration of the available data on cellulose pyrolysis suggests that, with relative importance depending upon heating rate in the temperature range 200-400°C, very pure cellulose decomposes by two competitive endothermic processes. lt is postulated that an unzipping reaction produces 1,4-anhydro-α-D-glucopyranose which rearranges to give levoglucosan. The other...

Airborne characterization of smoke marker ratios from prescribed burning

A Particle-Into-Liquid Sampler - Total Organic Carbon (PILS-TOC) and fraction collector system was flown aboard a Twin Otter aircraft sampling prescribed burning emissions in South Carolina in November 2011 to obtain smoke marker measurements. The fraction collector provided 2 min time-integrated offline samples for carbohydrate (i.e., smoke markers levoglucosan,...
