Components:

(1) 1,2-Dimethylbenzene, C₈H₁₀; [95-47-6] NIST WebBook
(2) Seawater, H₂O; [7732-18-5(C)] NIST WebBook

Original Measurements

Sutton, C.; Calder, J. A.; J. Chem. Eng. Data 1975, 20, 320-2.

Variables:

Ambient temperature: 25.0 °C
One salinity: 34.5 g salts/kg sln

Prepared by:

M. Kleinschmidt

Method/Apparatus/Procedure:

A test tube containing (1) was placed in a flask containing (2) thus allowing for equilibration through the vapor phase. The saturated solution was extracted with hexane and analyzed by gas chromatography.

Source and Purity of Materials:

1. From either Aldrich Chemical Co. or Matheson Coleman and Bell, 99+% pure.
2. made from doubly distilled water and salts 99+% pure.

Estimated Errors:

Ambient temperature: ±0.1°C
Mass concentration (m/v) (1): 1.8 (std. dev.)
