N,N-Diethylaniline → Anthraquinone

Participants

Reaction Steps

To a solution of 1-amino-2-(2-hydroxyphenyloxy)-4-hydroxy-5-chloroanthraquinone (3.82 g) in tetrahydrofuran (50 ml), N,N-diethylaniline (1.7 g) and 2,4-difluoro-6-(β-cyanoethyl)aminotriazine (1.85 g) were added and the mixture was subjected to condensation as in Example 3. The reaction liquor was treated as in Example 1 to produce 5.3 g of anthraquinone dye (λ max in acetone=527 nm) of the following formula in a yield of 93%. ##STR12## A dye dispersion was made from a mixture of the anthraquinone dye (16 parts), polyoxyethylene glycol nonylphenyl ether with an HLB of 13.3 (7 parts), naphthalene-sulfonic acid-formaldehyde condensate (3 parts) and water (74 parts) by grinding it with a sand grinder. Using the dye dispersion, a padding bath having the following formulation was prepared.
