Leinonen, P. J.; Mackay, D.; Can. J. Chem. Eng. 1973, 51, 230-3.
Variables:
Room Temp: 25 °C
Prepared by:
Z. Maczynska, A. Maczynski, A. Szafranski
Method/Apparatus/Procedure:
A mixture of (1) and (2) was equilibrated at 25 ± 0.1 °C for a minimum of 12 hrs in a 200-mL Teflon-stoppered vessel (25 cm long and 3.5 cm across) with gentle shaking, allowed to settle for 6 hrs and tested for the absence of emulsion (Tyndall effect). The aqueous and organic phases were analyzed by GLC with internal standardization) on a Hewlett-Packard Model 700 instrument equipped with a 15% SE-30 on 60/80 mesh acid-washed $\ce{(CH3)2Cl2Si}$-treated Chromosorb P column (steel capillary 10 ft x 0.125 inch). The (1) in the aqueous phase was extracted into 5 mL of heptane and the extract analyzed by glc.
Source and Purity of Materials:
- Phillip Petroleum Co. research grade, 99+ mole%; used as received.
- doubly distilled
Estimated Errors:
Ambient temperature: ±0.1 K
Mass concentration (m/v) (1): 30 mg(1) dm-3 (two standard deviations)
Components:
- Benzene, $\ce{ C6H6 }$; [71-43-2] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The solubility of benzene in water at 25°C was reported to be 1765 mg (1) dm-3 sln.
The corresponding mass percent and mole fraction, x1, calculated by the compilers are 0.1765 g(1)/100 g sln and 4.07 × 10-4.
The compiler's calculation assumes a solution density of 1.000 g mL-1.
