Notes:
*
The compiler extracted these data from the published graphs.
Method/Apparatus/Procedure:
The synthetic method was used. Solution temperatures were determined by cooling 3 to 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 nitriles 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 tetradecanoic acid over aluminium oxide in the presence of ammonia at 673 °C; dried and purified by vacuum distillation in a Stedman packed column; freezing point = 19.25 °C.
Estimated Errors:
Temperature: ± 0.4 K (below 248 K), ± 0.2 K (above 248 K).
