Vanillin almost instantly reduced 1.2 to 1.5 moles of aqueous chlorine dioxide at 20 °C. or 5 °C. and any pH between 1.2 and 6.5, and a white crystalline substance with the composition of a dihydroxyvanillin, C7H5O4(OCH3), was isolated in roughly 25% yield independently of the pH. When oxidized with aqueous sodium chlorite at 20 °C. and pH 0.5, these crystals gave another crystalline substance with the composition of a dihydroxyvanillic acid, C7H5O5(OCH3). Although both these substances… CONTINUE READING
