Versuchsvorschrift

1,2,3,4-Tetrafluoroanthraquinone and 25 g of p-cyanoaniline were charged in a 50 cc, four necked flask and then the reaction was carried out at 150° C. for about 3 hours. After completion of reaction, p-cyanoaniline was distilled out from the reaction solution and then a column purification using a column with a silica gel was effected to give rise to 2.46 g of 2,3-bis(p-cyanoanilino)-1,4-difluoroanthraquinone (Dye 18') (yield 72,3 mol %). The physical properties of Dye 18' and analytical values defining the compound are tabulated in table 23.
