Original Measurements

Francis, A. W.; Ind. Eng. Chem. 36, 1096-104 (1944).

Variables:

Ambient temperature: 349 - 379 K

Prepared by:

V.P. Sazonov

Method/Apparatus/Procedure:

The synthetic method was used. The reagents, about 1 mL of (1) and 1 to 1.5 mL of (2), were placed in tubes and stirred with a thermometer while the tubes were warmed gradually in a bath of water or glycerol. The temperature of disappearance or reappearance of the cloud due to two liquid phases was read three or four times in each direction. If the final position of the interface was not near the middle of the liquid, the volumes of the reagents were adjusted to make it so.

Source and Purity of Materials:

1. Source not specified; pure grade reagent.
2. Not specified.

Estimated Errors:

Ambient temperature: Not reported.
Mass concentration (m/v) (1): Not reported.
