Abstract

PURPOSE: To obtain the title compound useful as an intermediate for synthesis of azodinitriles of satisfactory purity in high yield, by reacting a cyanohydrin with NH3 or a ketone with hydrocyanic acid and NH3 in a specific molar ratio to liberate water formed.
CONSTITUTION: A cyanohydrin (C) of formula I: (R1 is 3W8C aliphatic, 3W8C alicyclic, or 6W10C aromatic hydrocarbon group) is reacted with NH3 (N) or a ketone (K) of formula II is reacted with hydrocyanic acid (H) and NH3 at a molar ratio of (H) to (K) of 1.05W1.3 or a molar ratio of (N) to (C) of 1.2W3.5 to give an α-aminonitrile of formula III.
EFFECT: The aminonitrile can be directly purified simply by separating water without adding caustic potash for water separation. Low cost of recovery and treatment of NH3 after the reaction renders the process advantageous to industrial application.
