Methodology:
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.
Sample Information:
- A.R. grade, thiophene-free, no further details given.
- Distilled, air-free
Measurement Errors:
Ambient temperature: Not specified.
System Components:
- Benzene, $\ce{ C6H6 }$; [71-43-2] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
Data at other pressures are presented in graphical form. Data are also presented for the solubilty of (1) in aqueous solutions of AgNO3 and KNO3 at various temperatures and pressures.
