IUPAC-NIST SOLUBILITY DATA SERIES. 99
Components: Original Measurements:
(1) 2-Acetoxybenzoic acid; 12A. K. Charlton, C. R. Daniels, W. E.
C9H804; [50-78-2] Acree, Jr., and M. H. Abraham, J.
(2) 2-Pentanol; C5H120; Solution Chem. 32, 1087 (2003).
[6032-29-7]
Variables: Prepared by:
T/K = 298.15 W. E. Acree, Jr.
Experimental Values
X2a Xlb
x2 x11b
0.9565 0.04345
x2: mole fraction of component 2 in the saturated solution.
bxl: mole fraction solubility of the solute.
Auxiliary Information
Method/Apparatus/Procedure:
Constant-temperature bath, calorimetric thermometer, and an ultraviolet/
visible spectrophotometer.
Excess solute and solvent were placed in amber glass bottles and allowed to
equilibrate for several days at constant temperature. Attainment of equilibrium
was verified by several repetitive measurements and by approaching
equilibrium from supersaturation. Aliquots of saturated solutions were
transferred through a coarse filter into tared volumetric flasks, weighed, and
diluted with methanol. Concentrations were determined by
spectrophotometric measurements at 272 nm.
Source and Purity of Chemicals:
(1) 99%, Aldrich Chemical Company, Milwaukee, WI, USA, was used as
received.
(2) 99+%, Acros Organics, USA, stored over molecular sieves and distilled
shortly before use.
Estimated Error:
Temperature: 0.1 K.
xl: 1.5% (relative error).
