4-Hydroxy-5- { (E) - [4- (phenylamino) -5-sulfonaphthalene-1-yl] diazo} naphthalene-2,7-disulfonic acid, the process of preparation is quite complicated.
At the beginning, naphthalene is taken as the group, and by sulfonation, the sulfonic acid group is introduced into the specific position of naphthalene to prepare sulfonated naphthalene derivatives. When it is sulfonated, it is necessary to carefully select the sulfonating reagent, such as concentrated sulfuric acid, fuming sulfuric acid, etc., and control its temperature and time to ensure that the sulfonic acid group is accurately connected to the naphthalene ring. This is related to the purity and yield of the product, and should not be careless.
Then, for the sulfonated naphthalene derivative prepared, the steps of amination are carried out. With a suitable amination reagent, such as an amino-containing compound, the amino group is substituted for a specific group on the naphthalene ring under specific reaction conditions to generate an amino-containing naphthalene sulfonate. The reaction conditions, such as pH, the choice and dosage of catalysts, have a great impact on the reaction process and results, and must be carefully considered and precisely regulated.
Then, the amino-containing naphthalene sulfonate and the aniline compound are diazotized and coupled to form the target product. During the diazotization reaction, the amino group is converted into a diazo group by reagents such as sodium nitrite in an acidic environment. This step requires strict temperature control to prevent the decomposition of diazo salts. The coupling reaction is the coupling of the diazo salt and the aromatic ring of the aniline compound to form an azo compound containing a diazo group. This process also requires attention to the reaction conditions, such as pH and temperature, so that the reaction can proceed smoothly in the direction of generating the target product.
The whole preparation process requires fine operation in each step and strict control of the reaction conditions to obtain high-purity 4-hydroxy-5- { (E) - [4- (phenylamino) -5-sulfonaphthalene-1-yl] diazo} naphthalene-2,7-disulfonic acid.
