Method/Apparatus/Procedure:
Constant temperature bath and a precision thermometer.
Mixtures of known concentrations sealed in glass tubes and placed in constant temperature to equilibrate. Samples were rotated while bath temperature slowly increased. Solubility determined by visual noting the temperature at which the last trace of solid solute disappeared. Measurements repeated several times to verify results.
Source and Purity of Materials:
(1) Purity and source not specified, was recrystallized several times from methanol to give a melting temperature of 80.05-80.10 ºC.
(2) Technical Grade, source not given, was distilled twice. Product showed slight color.
