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 NaOH aq., refluxed with Na, distilled; fraction boiling at 240°C was collected
   (3)Source not specified.

Estimated Errors:
   Solubility: Not reported.
   Temperature: Temp. ±0.01°C.
