Original Measurements

Yalkowsky, S. H.; Orr, R. J.; Valvani, S. C.; Ind. Eng. Chem. Fundam. 1979, 18(4), 351-3.

Variables:

Ambient temperature: One temperature

Prepared by:

A.L. Horvath

Method/Apparatus/Procedure:

A small excess of 1,2-difluorobenzene in water was agitated at room temperature for a period of about 24 hours and then filtered. The filtrate was diluted and assayed spectrophotometrically. The determination was done in duplicate.

Source and Purity of Materials:

1. Aldrich commercial grade, used as received.
2. Deionized.

Estimated Errors:

Ambient temperature: ±1 K.
Mass concentration (m/v) (1): ±10%.
