Reactive Red Brown K-B3r Usage And Synthesis

Preparation

2-Aminobenzoic acid diazo, and 7-Amino-4-hydroxynaphthalene-2-sulfonic acid coupling, and then chromium complexation; 2,4,6-Trichloro-1,3,5-triazine and 2-(4-Aminophenylsulfonyl)ethyl hydrogen sulfate condensation, triethylorthoformate condensation, again with complex product condensation, and salting-out.

Properties and Applications

Claret . Palm black powder. The strong sulfuric acid for black purple, diluted into purple, accompanied by precipitation; Nitric acid in the red for sauce, diluted for sauce is still red. The dye water solution is red sauce, add 1 Moore sodium hydroxide is still red sauce, continue to join insurance powder by shallow warm red to colorless; Add a boric acid sodium can’t restore the original colour and lustre.
