Diisopropylaniline → HCID 21836002, compound

Participants

Reaction Steps

2 g of 1,2,3,4-Tetrafluoroanthraquinone and 25 g of 2,6-diisopropylaniline were charged in a 50 cc, four necked flask and the reaction was carried out at 180° C. for about 6 hours. After completion of reaction, 2,6-diisopropylaniline was distilled out from the reaction solution and a column purification using a column with a silica gel was effected to give rise to 2.96 g of 2,3-bis(2,6-diisopropylanilino)-1,4-difluoroanthraquinone (Dye 24') (yield 69.7 mol %). The physical properties of Dye 24' and analytical values defining the compound are tabulated in Table 24.
