Method/Apparatus/Procedure:
   The solubility of (1) in (2) at room temperature and pressure was determined in a stoppered 1mm silica cuvette placed in a Unicam SP500 spectrophotometer and stirred magnetically. Measurements were made until a constant concentration was reached. The value was crosschecked against a 2-L sample of saturated solution which had been equilibrated for some months.
Solubilities at higher temperatures and pressures were similarly determined in a special cell fitted into the spectrophotometer. Many details of the apparatus are given in the paper.

Source and Purity of Materials:
