Aldotetronolactone forms a complex salt with molybdic acid and the optical rotation of the former at D line changes with complex formation. The rate at which this optical rotation reaches equilibrium is the fastest at pH 6 and a constant maximum value is reached after 24 hours. As a result of measurement by the continuous variation method and molar ratio method, binding ratio of aldotetronolactone to molybdic acid was found to be 2 : 1. Measurement of optical dispersion of the complex salt formed by the addition of molybdic acid to aldotetronolactone showed that the maximum rotations is present at 330 mμ in any of the lactones. Drude's monomial corresponding to these curves was calculated. The empirical rule of Okuda and others established between the sign of the Cotton effect and hydroxyl in 2-position of the lactone can also be applied to aldotetronolactone.
