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.
(1) Source not specified; best grade reagent; dried and twice distilled.
