Oxygen-Alkali Treatment of Cellobiose. [PDF]

Acta Chemica Scandinavica, 1975
C-(2,3-Dihydroxypropyl)tartronic acid is a major dicarboxylic acid formed during O2-NaOH and O2-NaHCO3 treatment of cellobiose. The observation that this acid is the main reaction product after alkali treatment of ascorbic acid in O2-free medium supports the conclusion that it is formed via an aglycon moiety related to ascorbic acid. Other dicarboxylic

MOLTEN ALKALI-ALCOHOL AND MOLTEN ALKALI TREATMENT OF LIGNITE: A COMPARATIVE STUDY

Fuel Science and Technology International, 1990
ABSTRACT The solubility of the Tuncbilek lignite is increased up to 100% on daf basis, after molten alkali-benzhydrol treatment. Meanwhile its oxygen, sulphur and ash-content are decreased considerably. Similar results are also obtained by simple molten alkeli treatment of lignite, although the oxygen content was increased in the product, A reductive ...
