Solubility System: Benzene with Water
Components:

(1) Benzene, C6H6; [71-43-2] NIST WebBook
(2) Water, H2O; [7732-18-5] NIST WebBook

Original Measurements

Roddy, J. W.; Coleman, C. F.; Talanta 1968, 15, 1281-6.

Variables:

Ambient temperature: One temperature: 25 °C

Prepared by:

Z. Maczynska, A. Maczynski

Method/Apparatus/Procedure:

A method for measuring the solubility of (2) in (1) was based on the use of tritium tracer to monitor the recovery of (2) in a conventional gravimetric method and to measure tritum distribution between the aqueous and the organic phases.

Source and Purity of Materials:
  1. source not specified; thiophene free regent; recrystallized three times.
  2. HTO at 5 Ci/mL, New England Corp.; diluted to about 1 mCi/mL.
Estimated Errors:

Mass concentration (m/v) (1): better than 1% (type of error not specified).

Experimental Values:
Note: The solubility of water in benzene at 25°C was reported to be x2 = 3.23 × 10-3 and 0.0363 mol (2) dm-3 sln.
The corresponding mass percent value calculated by the compilers is 0.0747 g(2)/100 g sln.
