Method/Apparatus/Procedure:
   The synthetic method was used. 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

Source and Purity of Materials:
   (1) Source not specified; best grade; freshly distilled.
   (2) Prepared by direct esterification of highly purified fatty acid with the appropriate alcohol; fractionated under a vacuum in a Stedman-packed column; freezing point = 31.36 °C.

Estimated Errors:
   Solubility: Not reported.
   Temperature: Not reported.
