2,6-Diethylaniline → HCID 21836040, compound

Participants

Reaction Steps

2 g of 1,2,3,4-Tetrafluoroanthraquinone and 25 g of 2,6-diethylaniline were charged in a 50 cc, four necked flask and the reaction was carried out at 160° C. for about 8 hours. After completion of reaction, 2,6-diethylaniline 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 2.87 g of 2,3-bis(2,6-diethylanilino)-1,4-difluoroanthraquinone (Dye 23') (yield 74.6 mol %). The physical properties of Dye 23' and analytical values defining the compound are tabulated in table 24.
