Method/Apparatus/Procedure:
A small excess of solute in water was agitated for a period of 4-48 hours (the exact time for equilibration was not reported in single cases) and then filtered. The saturated solution was extracted with a small volume of methylene chloride which was then assayed spectrophotometrically. At lease two independent determinations were carried out.
Source and Purity of Materials:
- Commercial product (Aldrich or Eastman), used as received.
- Source and purity not specified.
Estimated Errors:
Ambient temperature: ±1 K (authors).
Mass concentration (m/v) (1): ±10% (authors).
Components:
- 1,2,3,4-Tetrachlorobenzene, $\ce{ C6H2Cl4 }$; [634-66-2] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
