Parsons, G. H.; Rochester, C. H.; Wood, C. E. C.; J. Chem. Soc. B 1971, 533-6.

Variables:

Room Temp: 25 °C

Prepared by:

A. Vesala

Method/Apparatus/Procedure:

The experimental prcedure was probably similar to that reported in [1]. Excess solid was shaken with water at 25 ± 0.1 °C for 24 hours. The saturated solution was then filtered at thermostat temperature and, with appropriate dilution, analyzed spectrophotometically. Linear calibration graphs of absorbance at a wave length of maximum absorbance of the neutral phenols against concentration confirmed the applicability of the Beer-Lambert law for the analysis.

Source and Purity of Materials:

1. Commercial product (manufacturer not reported), recrystallized to a constant melting point.
2. Source and purity not specified.

Estimated Errors:

Mass concentration (m/v) (1): ±2% (standard deviation of the average value from five determinations as reported by the authors).
