IUPAC-NIST SOLUBILITY DATA SERIES. 99
Components: Original Measurements:
(1) Benzoic acid; C7H602; 87M. Dias, J. Hadgraft, and M. E. Lane,
[65-85-0] Int. J. Pharm. 336, 108 (2007).
(2) Ethyl 2-hydroxypropanoate;
C5H100oO3; [97-64-3]
Variables: Prepared by:
T/K = 305.2 W.E. Acree, Jr.
Experimental Values
The measured solubility was reported to be 164.70 mg/ml,
which corresponds to a molar solubility of c1- 1.349
mol dm-3.
Auxiliary Information
Method/Apparatus/Procedure:
Constant-temperature bath, magnetic stirrer, centrifuge, and an ultraviolet/
visible spectrophotometer.
Excess solute and solvent were equilibrated in a constant-temperature bath
with stirring for 48 h. The saturated solution was then centrifuged for 10 min,
and an aliquot of the supernatant solution was removed and diluted
quantitatively for spectrophotometric analysis. The concentration of the
dissolved solute was determined from the measured absorbance.
Source and Purity of Chemicals:
(1) Purity not given, Fisons Scientific Equipment, UK, no purification details
were provided.
(2) Purity not given, Purac Biochem, Gorinchem, Netherlands, no purification
details were provided.
Estimated Error:
Temperature: Insufficient experimental details to estimate.
c1: 0.20.
Components: Original Measurements:

(2) 1-Methylethyl 2-
hydroxypropanoate; C6H1203;
[617-64-3]
Variables: Prepared by:
T/K = 305.2 W.E. Acree, Jr.
Experimental Values
The measured solubility was reported to be 239.70 mg/ml,
which corresponds to a molar solubility of c1- 1.963
mol dm-3'.
