Solubility System: Cumene with Artificial seawater
Components:

(1) iso-Propylbenzene, C9H12; [98-82-8] 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): 0.2 (std. Dev.)

Experimental Values:
Note: The solubility of cumene (isopropylbenzene) in artificial seawater is reported to be 42.5 mg(1)/kg sln. The corresponding mass percent and mole fraction, x1, calculated by the compiler are 4.25 × 10-3 g(1)/100 g sln and 6.54 × 10-6 assuming the artificial seawater composition of ref 1.
