Versuchsvorschrift
After addition of 0.25 g of KOH, dissolved in 2.5 ml of methanol, to 15.0 g of 2,4-pentandione, 35.0 g of acrylonitrile was added dropwise with the reaction temperature not exceeding 40° C. The product which was precipitated during the process was filtered off, washed with a small amount of acetone, and dried. Melting point: 185–186° C. Purity>98%. The product was colorless.
