The solubilities were determined by observing visually the temperature at which crystals appear upon cooling and dissolve upon heating solutions containing known concentrations of solutes. The procedure and equipment were described elsewhere [1]. The International Union of Pure and Applied Chemistry Hoerr, C. W.; Binkerd, E. F.; Pool, W. O.; Ralston, A. W.; J. Org.
