Zusammenfassung:PURPOSE:To purify waste liquid of acrylonitrile containing acids as impurities in high efficiency by neutralizing the waste acrylonitrile and removing the generated neutralized salt. CONSTITUTION:Acrylonitrile containing acids as impurities is brought into contact with a base and water to form a water-soluble salt by the neutralization reaction of the base with the acid in the acrylonitrile and the water layer containing the water-soluble salt is separated and removed from the reaction product.
