Carbohydrate reactions during treatment of kraft pulp and cotton with alkaline peroxide

Kraft pulp and alkali-cooked cotton have been treated with hydrogen peroxide in the presence of alkali. The alditol (produced by reduction) and acid end-groups were isolated by chromatography. It is concluded that existing deoxyaldonic acid end-groups are partly destroyed and new reducing end-groups...

Description
Summary:Kraft pulp and alkali-cooked cotton have been treated with hydrogen peroxide in the presence of alkali. The alditol (produced by reduction) and acid end-groups were isolated by chromatography. It is concluded that existing deoxyaldonic acid end-groups are partly destroyed and new reducing end-groups are produced, which, in turn, are degraded stepwise until the glycosidic bond is reached. Further degradation is then retarded. The presence of hexonic acid end-groups and C-(2,3-dihydroxypropyl)tartronic acid in the spent liquor obtained after treatment of hydrocellulose indicate that carbonyl groups have been introduced oxidatively.
