Summary

  1. 1.

    The solubility composition isotherms of camphoric acids in water at 25° C., 45° C. and at the boiling points of the solutions have been determined. In each case three curves have been obtained showing that the racemic form is a truedl-compound at these temperatures.

  2. 2.

    The results obtained by the solubility method are in agreement with those already obtained from melting point data.

  3. 3.

    The temperature of transition of racemic camphoric acid from the compound into the mixture of optically active and opposite forms has been discussed.
