Abstract
A process for the alkaline oxidative degradation of an ose, a ulose, their polymers or their mixtures, in aqueous solution in the presence of a redox pair consisting essentially of a mixture of 2-anthraquinone monosulfonic acid and hydrogen peroxide, wherein oxidizing gas is air and said air is stir-beaten and introduced into the reaction medium under stirring conditions and at a flow rate such that the oxygen-saturation of the reaction medium leads to the production of a pink color in this reaction medium.
