Summary

  1. (1)

    The solubility-composition isotherm of mixtures of active and inactive camphor carboxylic acid in water at 30°C. has been determined.

  2. (2)

    The isotherm consists of three curves with two isothermal invariant points indicating the inactive acid to be adl-compound.

  3. (3)

    The melting point-composition curves of mixtures of active and inactive camphorcarboxylic acids have also been determined.

  4. (4)

    The curve shows two well pronounced minima (eutecti) showing that the inactive acid is adl-compound, in conformity with the solubility results.
