Variables:

Room Temp: 25 °C

Prepared by:

Z. Maczynska, A. Maczynski

Method/Apparatus/Procedure:

A mixture of (1) and (2) was rotated for twenty hours in a constant temperature bath at 25 °C. A sample (5 - 20 mL) of the aqueous phase was withdrawn and extracted with a measured volume of hexane (10 - 50 mL) by shaking in a glass-stoppered Erlenmeyer flask.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., best grade; washed successively with concentrated sulfuric acid, water, and dilute sodium hydroxide; dried, and distilled; BP = 80°C.
2. Not specified.
