Abstract
PURPOSE: To obtain aminonitrile of satisfactory purity in high yield, by vacuum distillation of crude aminonitrile, obtained through the reaction between a cyanohydrin and NH3, under specific conditions to distil away low boiling substances consisting mainly of NH3.
CONSTITUTION: A cyanohydrin of formula I: (R1 and R2 are 1W8C aliphatic, 3W8C alicyclic, or 6W10C aromatic hydrocarbon group) is reacted with NH3, or a ketone of formula II is reacted with hydrocyanic acid and NH3 to form a crude aminonitrile of formula III, which is vacuum distilled at a heater temperature of 5W50°C and a pressure of 400 mmHg or below to distil away low-boiling substances consisting mainly of NH3, thus purifying the aminonitrile.
EFFECT: The aminonitrile is scarcely decomposed even in the presence of water.
USE: An intermediate for synthesis of azodinitriles.
