Abstract (en)
[origin: WO9720860A1] The invention relates to a process for the alcaline oxidative degradation of an ose, an ulose, polymers or mixtures thereof in aqueous solution and in the presence of a redox couple comprised of a mixture of monosulfonic anthraquinone-2-acid and of hydrogen peroxide, characterized in that the oxidant gas is air and said air is stirred up and introduced into the reaction medium in agitation flow rate conditions and such that the dissolved oxygen saturation of the reaction medium gives a pink coloration of said reaction medium.
