On the Quantitative Determination of Sorbitol by Oxydative Splitting by Means of Periodic Acid. The oxydative splitting reaction of polyhydroxy compounds with vicinal hydroxyl groups by means of periodic acid or periodates can be applied with advantage to the determination of sorbitol concentration, especially in case of working with simple equipment. The oxydative splitting reaction leads to three reactive substances which can be determined by iodometric or acidimetric titration, i.e. a) remaining periodate, b) formaldehyde, and c) formic acid. The practicability of the three resulting methods of determination has been examined with three different commercial samples of sorbitol. The mathematic‐statistical interpreted data show that only the determination of remaining periodate leads to results which are in accordance with the theoretical sorbitol concentration.
