 Method/Apparatus/Procedure:
   The synthetic method, as described in Broughton,1 was used. Liquids were pipetted into glass tubes. Temperatures at which complete miscibility occurred were measured by thermometers standardized against thermometers having NPL certificates.

 Source and Purity of Materials:
   (1) Prepared from sodium monochloroacetate with sodium nitrite; distilled; n(25 °C, D) = 1.3796, d(25 °C) = 1130.8 g·L-1.
   (2) Source not specified; purified according to Jones and Betts2 (recrystallized from petrol ether, m. p. = 39 °C, recrystallized from petrol ether and acetone, m. p. = 43.4 °C).

 Estimated Errors:

   Temperature: ± 0.05 K.
