Components:

(1) Styrene, C₈H₈; [100-42-5] NIST WebBook
(2) Water, H₂O; [7732-18-5] NIST WebBook

Original Measurements

Andrews, L. J.; Keefer, R. M.; J. Am. Chem. Soc. 1950, 72, 5034-7.

Variables:

Ambient temperature: 25 °C

Prepared by:

Z. Maczynska, A. Maczynski

Method/Apparatus/Procedure:

A mixture of (1) and (2) was rotated for twethy hours in a constant temperature bath as 25°C. A sample (5-20 mL) of the aqueous phase was withdrawn and extracted with a measured volume of hexane (10-50 mL) by shaking in a glass-stoppered Erlenmeyer flask. Next, the absorbance of the hexane phase was measured against a hexane blank on the Beckman spectrophotometer.

Source and Purity of Materials:

1. Eastman Kodak Co., white label; distilled shortly before use; 1 wt% of hydroquinone added as stabilizer before distillation; b.p. 76 C (78 mm Hg).
2. not specified.

Estimated Errors:

Ambient temperature: Not specified.
