Original Measurements

Prutton, C. F.; Walsh, T. J.; Desai, A. M.; Ind. Eng. Chem. 42, 1210-7 (1950).

Variables:

Room Temp: 298 and 308 $\pu{K}$

Prepared by:

A. Skrzecz

Method/Apparatus/Procedure:

The analytical method was used. Samples in 4 oz. oil sample bottles were agitated in a constant temperature bath for at least 12 h. before phase separation. Samples of each phase were taken for analysis by a rubber bulb pipette. Water was determined by the Karl Fischer reagent, hydrocarbons as the caustic-insoluble fraction, methanol-by the difference.

Source and Purity of Materials:

1. Barker C.P. analyzed absolute; purity 99.5%; water-free by the Karl Fischer.
2. (a) Eastman Kodak Co., distillation range 238-240°C, contained about 5% of 2-methylnaphtalene isomer. (b) prepared in the laboratory from the crude material; extracted with $\ce{NaOH}$ aq., refluxed with $\ce{Na}$, distilled; fraction boiling at 240°C was collected
3. Source not specified.

Estimated Errors:

Ambient temperature: Temp. ±0.01°C.
Mass concentration (m/v) (1): Not reported.
