Manufacturing Methods :  Benzaldehyde  with sulfuric acid and nitric acid nitrification, use the method reduction, with vinegar anhydride acylation, with sulfuric acid nitrification and nitric acid, hydrochloric acid and iron powder reduction, first and 4-Formylbenzene-1,3-disulfonic acid condensation, again with 3-Amino-4-hydroxybenzenesulfonic acidcondensation, copper complexation, then with 5-Chloro-2,4,6-trifluoropyrimidine condensation.

Properties and Applications: bright blue. Blue-black powder, water solution is bright blue, poor solubility. The strong sulfuric acid for navy, diluted for brown; In the nitric acid is shallow brown, precipitation, diluted into light yellow. The dye water solution is colourful blue, with 1 Moore sodium hydroxide solution is still bright blue; Continue to join insurance powder and warm, into a colourless; Add a boric acid sodium can’t restore the original colour and lustre.
