How is Disodium 3,3 '- [Biphenyl-4,4' -Diyldi (E) Diazene-2,1-Diyl] Bis (4-Aminonaphthalene-1-Sulfonate) prepared?

To prepare disodium 3,3 '- [biphenyl-4,4' -diylbis (E) diazene-2,1-diyl] bis (4-aminonaphthalene-1-sulfonate), you can follow the following method:
First, you need to prepare biphenyl-4,4 '-diamine and 4-aminonaphthalene-1-sulfonic acid and other raw materials. Add an appropriate amount of biphenyl-4,4' -diamine to a suitable reaction vessel, dissolve it and form a salt. This acid can be selected from common inorganic acids such as hydrochloric acid to promote the conversion of amine groups into ammonium salts and enhance its reactivity.
Next, slowly add an appropriate amount of sodium nitrite solution dropwise to the reaction system. This process requires strict control of the reaction temperature, generally maintained between 0-5 ° C, to prevent the reaction from being too violent and producing side reactions. Sodium nitrite reacts with ammonium salts to form diazonium salt intermediates. During the reaction, attention should be paid to stirring evenly to make full contact with the reactants to ensure the smooth progress of the reaction.
Subsequently, 4-aminonaphthalene-1-sulfonic acid is dissolved in a basic solution to form a corresponding salt solution. The base used can be selected from sodium hydroxide, etc., and the pH of the solution is adjusted to a suitable range, generally about 8-10.
After the formation of the diazonium salt intermediate is completed, under stirring conditions, slowly add the 4-aminonaphthalene-1-sulfonate solution dropwise to the diazonium salt reaction system. This coupling reaction process also needs to control the temperature, which is maintained at about 5-10 ° C. During the reaction, the diazonium salt is coupled with 4-aminonaphthalene-1-sulfonate to form a crude product of disodium 3,3 '- [biphenyl-4,4' -diylbis (E) diazene-2,1-diyl] bis (4-aminonaphthalene-1-sulfonate).
After the reaction is completed, the reaction mixture is treated. An appropriate amount of salts such as sodium chloride can be added to promote the product to be salted out and precipitated. After that, the precipitation is separated by filtration means. Then the precipitation is washed with an appropriate amount of water or organic solvent to remove impurities. After washing, the product is dried to obtain a relatively pure disodium 3,3 '- [biphenyl-4,4' -diylbis (E) diazene-2,1-diyl] bis (4-aminonaphthalene-1-sulfonate) product. The entire preparation process requires strict control of various reaction conditions to ensure the purity and yield of the product.

What are the physicochemical properties of Disodium 3,3 '- [Biphenyl-4,4' -Diyldi (E) Diazene-2,1-Diyl] Bis (4-Aminonaphthalene-1-Sulfonate)?
