Andrews, L. J.; Keefer, R. M.; J. Am. Chem. Soc. 1950, 72(7), 3113-6.

Variables:

Room Temp: 25.0 °C

Prepared by:

A. Vesala

Method/Apparatus/Procedure:

Water was saturated with 1,4-dichlorobenzene in a sealed Erlenmeyer flask by rotating the flask in a constant temperature bath for 20 hours. Measured volumes of the saturated solutions were extracted with measured volumes of n-hexane for analysis. The optical density of the extract was measured against a n-hexane standard at 234 nm using a Beckman spectrophotometer [1].

Source and Purity of Materials:

1. Commercial product (Eastman Kodak Co.) used as received.
2. distilled.

Estimated Errors:

Ambient temperature: ±0.2 K (compiler).
Mass concentration (m/v) (1): >10% (compiler).
