Methodology:
The synthetic method was used. Solution temperatures were determined by cooling 3-5 g portions of solution in 1 cm x 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.
Sample Information:
- Source not specified; best grade reagent; dried and twice distilled.
- Prepared by passing hexadecanoic acid over aluminium oxide in the presence of ammonia at 400°C; dried and purified by vacuum distillation in a Stedman packed column; FP = 31.40°C.
Measurement Errors:
Ambient temperature: ±0.4 K (below 248 K), ±0.2 K (above 248 K).
System Components:
- Acetonitrile, $\ce{ C2H3N }$; [75-05-8] NIST WebBook
- Hexadecanenitrile, $\ce{ C16H31N }$; [629-79-8] NIST WebBook
