実験手順

Another colorant stabilizer of the present invention is a basic fuschin hydrazone, prepared as follows. To a 500 ml round bottom flask, fitted with a magnetic stirrer and a heating mantle, was placed 50 g (0.46 mole) phenyl hydrazine (Aldrich), 96.3 g (0.46 mole) chalcone (Aldrich), and 300 ml. of anhydrous ethanol. The reaction mixture refluxed overnight and then cooled to room temperature. A white precipitate formed and was filtered to yield a white solid which was washed with cold ether. 128 g (93%) chalcone hydrazone was obtained. This reaction is shown below.
