Thermal degradation of 3-deoxy-D-erythro-hexosulose

3-Deoxy-D-erythro-hexosulose is less stable than normal carbohydrates and polymerizes within the range 100-200^o. The polymerization is accompanied by dehydration, fission, and rearrangement reactions which produce water, furan derivatives, carbonyl compounds of low molecular weight, saccharinic aci...

3-Deoxy-D-erythro-hexosulose is less stable than normal carbohydrates and polymerizes within the range 100-200^o. The polymerization is accompanied by dehydration, fission, and rearrangement reactions which produce water, furan derivatives, carbonyl compounds of low molecular weight, saccharinic acid, carbon dioxide, and carbon monoxide. Heating at higher temperatures results in charring of the polymeric material and further dehydration, fission, and disproportionation reactions which provide a variety of secondary pyrolysis products. The dehydration reactions are catalyzed by the addition of zinc chloride, and the fission reactions by the addition of sodium carbonate. Ausführliche Beschreibung
