 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 a set of 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 and ethanol, m. p. = 62.6 °C).

 Estimated Errors:

   Temperature: ± 0.05 K.
