Method/Apparatus/Procedure:
   The synthetic method was used. Solution temperatures were determined by cooling 3 - 5 g portions of solution in 1 cm×15 cm test tubes, which were placed in an air-bath. The latter was immersed in an acetone-bath, which was cooled with solid carbon dioxide. Temperature within the samples was measured by means of a potentiometer with an iron-constantan thermocouple. As the nitrile crystallized from solution upon cooling, the temperature of the air-bath was raised gradually until the mixtures redissolved.

Source and Purity of Materials:
   (1) Source not specified; best grade reagent; dried and twice distilled.
   (2) Prepared by passing the tetradecanoic acid over aluminium oxide in the presence of ammonia at 673 °C; dried and purified by vacuum distillation in a Stedman packed column; f. p. = 19.25 °C.

Estimated Errors:

   Temperature: ±0.4 K (below 248 K), ±0.2 K (above 248 K).
