Participants

Reaction Steps

A dispersion of 22.3 parts of 1-aminoanthraquinone in 200 ml of nitrobenzene was brought to 100° C. and additioned with 9.22 parts of cyanuryl chloride and successively brought to 190° C. for 2 hours. The reaction mixture was filtered at a temperature of 150° C. and the cake was washed several times with methanol and then with n-heptane and was dried in an oven at a temperature of 110° C. About 23 parts of 2-chloro-4,6-bis-(1-aminoanthraquinonyl)-s-triazine were obtained.
