Abstract

PURPOSE: To recover the title compound useful as a raw material for α-picoline or resorcinol in high yield, by pretreating a reaction mixture containing a cyanoethylated ketone with water and an inorganic base, and by distilling the mixture.
CONSTITUTION: Arylonitrile is reacted with a ketone, e.g. acetone, in the presence of a primary amine or its Schiff base, and an acid to give a cyanoethylated ketone. The reaction mixture is pretreated with water and an inorganic base, preferably an alkali metal compound, e.g. NaOH, in an amount equivalent to the acid, and distilled to recover the cyanoethylated ketone. The amount of water is one mole or more per mole of the amine or Schiff base.
EFFECT: Simple isolation procedures of the unreacted ketone, acrylonitrile, and high-boiling by-products.
