Reactive Orange 5

Orange powder. Solubility in water (50℃) is 70g/L. Aqueous solution is golden yellow, add 1mol/L sodium hydroxide to dark yellow, then add insurance powder and warm to light yellow, then add sodium perborate is still light yellow. In concentrated sulfuric acid, it is dark reddish sauce color, with precipitation, after dilution, it is golden yellow. Golden yellow in concentrated nitric acid, light yellow after dilution.

Using aniline-2, 5-bissulfonic acid, J acid, cyanuric chloride and m-aminobenzenesulfonic acid as raw materials, first condense J acid and cyanuric chloride, and then reconstitute aniline-2, 5-bissulfonic acid. After nitriding, it is coupled with the above condensation product, and finally with m-aminobenzenesulfonic acid for the second condensation to obtain the product. After salting out, filtering and drying, the finished product is obtained. . . Condensation of 0.2625kmol cyanuric chloride and 0.25kmol J acid in a hydrochloric acid medium at a temperature of 0-5℃ to obtain (I). Take 0.25kmol aniline-2, 5-bissulfonic acid after diazotization and couple with (I) to remove insoluble impurities to obtain (II), and then condense with 0.275kmol m-aminobenzenesulfonic acid at a temperature of 40℃ for 3h, then salt out , Filtered and dried to obtain the finished product. The latest research results can be found in Active Orange X-GN.
