The physicochemical properties of "disodium 7,7 '-iminobis (4-hydroxy-3- (phenylazo) naphthalene-2-sulfonate) " in "Tiangong Kaiwu"
"disodium 7,7' -iminobis (4-hydroxy-3- (phenylazo) naphthalene-2-sulfonate) " are chemical substances. Its color, or bright color, is often different due to the environment. Viewed under light, it can be seen that its color is unique, or bright and brilliant, and its structure contains special chromogenic groups, and the structure of phenylazo and other structures causes it to have a significant color effect.
In terms of its solubility, it can have a certain solubility in water or specific polar solvents. The cover has a sulfonate group in its molecular structure, which is hydrophilic and can interact with water molecules. Therefore, it can be partially or completely dissolved in polar media such as water. However, the degree of solubility is also determined by factors such as temperature and pH of the solvent. Increased temperature may promote its dissolution; and changes in pH can also change the degree of ionization, which in turn affects the dissolution.
As for stability, the azo bond and other parts of its structure may be active under certain conditions. It may change under heat, light or specific chemical reagents. Under high temperature, the azo bond may break, causing its structure to change and affecting its original properties. When illuminated, it may also lead to luminescent chemical reactions, causing its color or other properties to change.
And its acidity and alkalinity, due to the presence of hydroxyl groups and sulfonate groups, hydroxyl groups can weakly ionize hydrogen ions under appropriate conditions, while sulfonates can be hydrolyzed to be alkaline, so its acidity and alkalinity depend on the specific environment. In media with different pH values, its morphology and properties will change accordingly. This is the approximate physical and chemical properties of "Disodium 7,7 '-imino bis (4-hydroxy-3- (phenylazo) naphthalene-2-sulfonate) ".

When preparing the bisodium salt 7,7 '-iminobis (4-hydroxy-3- (phenylazo) naphthalene-2-sulfonate), it is necessary to pay attention to many key matters.
Quality of the first raw material. The purity and characteristics of the raw material have a great impact on the quality and yield of the product. The raw materials must be carefully screened and its various indicators must be strictly controlled. Inferior or substandard raw materials must not be used, so as not to disrupt the reaction process and increase the impurities of the product.
The second time is the reaction condition. Temperature, pH value and reaction time are all key factors. If the temperature is too high or too low, the reaction rate may be abnormal or by-products may be formed. The precise regulation of pH value is related to the direction and process of the reaction. It must be monitored and adjusted with precision instruments according to the characteristics of the reaction. The reaction time should not be sloppy. If it is not enough, the reaction will not be completed, and if it is too long, it will cause an overreaction, which is not conducive to the formation of the product.
Furthermore, the cleanliness of the reaction environment should not be underestimated. During the preparation process of this compound, minor impurities may also interfere with the reaction or affect the purity of the product. Therefore, the reaction equipment must be thoroughly cleaned and dried, and the operating environment should also be kept clean to avoid the mixing of external impurities.
The stirring rate is also particular. Moderate stirring can promote the full contact of the reactants, accelerate the reaction process, and make the reaction more uniform. If the rate is too fast or too slow, After
and product separation and purification. After the reaction is completed, select a suitable separation method to separate the product from the reaction system. Then by recrystallization, chromatographic separation and other means, the product is further purified to ensure its purity.
In short, the preparation of this compound requires careful attention from raw materials, reaction conditions, environment, stirring and product treatment to obtain the ideal product.
