Versuchsvorschrift
2 g of 1,2,3,4-Tetrafluoroanthraquinone and 25 g of 2-chloro-6-methylaniline were charged in a 50 cc, four necked flask and then the reaction was carried out at 140° C. for about 6 hours. After completion of reaction, 2-chloro-6-methylaniline was distilled out from the reaction solution and a column purification thereof was effected to give rise to 1.07 g of 2-(2-chloro-6-methylanilino)-1,3,4-trifluoroanthraquinone (Dye 8') yield 37.3 mol %) and 0.78 g of 2,3-bis(2-chloro-6-methylanilino)-1,4-difluoroanthraquinone (Dye 21') (yield 24.2 mol %). The physical properties of Dye 8' and analytical values defining the compound are tabulated in Table 22 and the physical properties of Dye 21' and analytical values defining the compound are tabulated in Table 24.
