IUPAC-NIST SOLUBILITY DATA SERIES. 99
Components: Original Measurements:
(1) Benzoic acid; C7H602; 86D. H. Wester and A. Bruins, Pharm.
[65-85-0] Weekbl. 51, 1443 (1914).
(2) Trichloroethene; C2HC13;
[79-06-1]
Variables: Prepared by:
T/K = 288.15 W. E. Acree, Jr.
Experimental Values
X2a X1b
0.9307 0.0693
ax2: mole fraction of component 2 in the saturated solution.
bx1: mole fraction solubility of the solute.
Auxiliary Information
Method/Apparatus/Procedure:
Excess solute and solvent were continuously shaken in a water bath at 303 K for
1 h. The solution was then transferred to a cellar which was maintained at a
constant temperature of 288 K. The solution was allowed to equilibrate in the
cellar for at least two days with repeated shaking. The concentration of the
dissolved solute was determined; however, the analytical method was not
described.
Source and Purity of Chemicals:
(1) Purity not given, Chemical source not specified, no information provided
concerning purification.
(2) Purity not given, Chemical source not specified, no information provided
concerning purification.
Estimated Error:
Temperature: 0.2 K.
xl: Not enough information in paper to estimate an uncertainty.
Components: Original Measurements:
(1) Benzoic acid; C7H602; 66W. Herz and W. Rathmann, Z.
[65-85-0] Elektrochem. 19, 887 (1913).
(2) Tetrachloroethene; C2C14;
[127-18-4]
Variables: Prepared by:
T/K = 298.15 W. E. Acree, Jr.
Experimental Values
The measured molar solubility was c1 = 0.660 mol dm-3 .
Auxiliary Information
Method/Apparatus/Procedure:
Very little experimental details were provided. Excess solute and solvent were
shaken in a thermostat at 298 K. After equilibrium was reached and the solid
phase settled to the bottom of the container, an aliquot of the saturated clear
solution was removed by pipet. The concentration of the solute in the saturated
solution was determined by titration.
Source and Purity of Chemicals:
(1) Purity not given, Chemical source not given, no purification details were
provided.(2) Purity not given, Chemical source not given, no purification details were
provided.Estimated Error:
Temperature: No information was given.
c1: 4% (relative error, estimated by compiler).
Components: Original Measurements:

[65-85-0] Martin, J. Pharm. Sci. 73, 179 (1984).
(2) Chlorobenzene; C6H5C1;
[108-90-7]
Variables: Prepared by:
T/K = 298.15 W. E. Acree, Jr.
Experimental Values
X2a 1b
0.9138 0.0862
ax2: mole fraction of component 2 in the saturated solution.
bxl: mole fraction solubility of the solute.
Auxiliary Information
Method/Apparatus/Procedure:
Constant-temperature bath and ultraviolet/visible spectrophotometer.
Excess solute and solvent were placed in screw-capped vials. The vials were
sealed and submerged in a constant-temperature water bath and shaken at 100
cycles/min for 24 h. After the 24 h equilibration period, the vial was removed,
wiped dry, and the contents analyzed. The solutions were transferred to a
syringe and filtered through a 0.1 pm pore size filter. The solutions were diluted
and the absorbances recorded at the maximum absorption wavelength of
benzoic acid. The solubility was determined at least six times.
Source and Purity of Chemicals:
(1) Purity not given, Chemical source not specified, no information provided
concerning purification.
(2) Spectrophotometric or ACS Reagent grade, Chemical source not specified,
redistilled before use.
Estimated Error:
Temperature: 0.2 K.
xl: 3% (relative error).
