Alkaline degradation of larch arabinogalactan (AG) involves rapid peeling of the (1→3)-galactan main chain from the reducing end. The products are the original side chains attached to galactometasaccharinic (GalMS) acids derived from main-chain res

At the molecular level, larch arabinogalactan (AG) fragments into subunits when exposed to mild alkali or heat. This process is accompanied by a large increase in NMR spectral resolution, especially for NMR signals associated with main-chain units, a

Arabinogalactan (AG) from Western larch has sometimes been reported to contain a small proportion of uronic acid units. This concept is supported and extended by the present work, which shows that these units occur in some AG molecules. Molecular ass

Thermal treatment of anhydrous, acidified sucrose or inulin yields caramels containing monosaccharides and oligomers, predominantly dianhydrides and higher oligomers derived by the addition of glycosyl residues to dianhydrides. Fourteen dianhydrides,

Gasifications of 350 o C chars from wood sorbed with Fe 2 (SO 4 ) 3 , FeSO 4 , and CuSO 4 were carried out under a flow of nitrogen at 500, 800, and 950 o C. Chars from wood treated with (NH 4 ) 2 SO 4 , (NH 4 ) 2 HPO 4 , and H 2 SO 4 were also gasif

The major condensible products (−45°C) from smoldering combustion of ponderosa pine sapwood have been identified and quantified. Methylene chloride extracts of the condensate, as well as nonextracted condensate, were analyzed by gas chromatography

In seeking to gain a better understanding of the pyrolysis of polysaccharides, the pyrolytic behavior of a variety of naturally occurring and synthetic polysaccharides has been studied. Among the former were various glucans containing different linka
