Abstract (en)
Process for producing (poly)oxatetramethylenedicarboxylic acids of the general formula HOOCC3H6(OC4H8)n-OC3H6COOH (I> in which n is an integer from 0 to 20, by electrolytic oxidation of polytetrahydrofurans of the general formula HOCH2C3H6(OC4H8)n-OC3H6CH2OH(II> in aqueous alkaline medium in the presence of an electrochemically regenerable redox catalyst.
