Frequently Asked Questions
What is the chemical structure of Sodium 3 - Hydroxy - 4 - (2 - Hydroxy - 1 - Naphthylazo) -7 - Nitronaphthalene - 1 - Sulphonate?
This is the chemical name of sodium-3-hydroxy-4- (2-hydroxy-1-naphthyl azo) -7-nitronaphthalene-1-sulfonate. To clarify its chemical structure, let me explain in detail.
In this compound, the naphthalene group is the core structure. Naphthalene has two fused benzene rings, and its numbering rules are established. In the first position of the naphthalene ring, there is a sulfonate group (-SO 🥰 Na), which gives the compound a certain water solubility. At the 3rd position, it is a hydroxyl group (-OH). The oxygen of the hydroxyl group has a lone pair of electrons, which can participate in the formation of hydrogen bonds and affect the physical and chemical properties of compounds.
At the 4th position, another naphthalene fragment is connected through an azo group (-N = N -). This azo group is a chromophore, which often gives the compound color and is common in the field of dyes. The linked naphthalene group has a hydroxyl group at the 1st position, which can also participate in hydrogen bonding and other interactions.
At the 7th position, there is a nitro group (-NO _ 2). Nitro is an electron-withdrawing group, which can affect the distribution of naphthalene ring electron clouds and change the reactivity of compounds.
The structure of this compound, the mutual influence of each group, endows it with unique physical and chemical properties, and may be used in dyes, analytical reagents, etc. Because it contains azo groups that can develop color, sulfonates help to dissolve, and hydroxyl and nitro groups can participate in various reactions, it has practical value in specific fields.

What are the physical properties of Sodium 3 - Hydroxy - 4 - (2 - Hydroxy - 1 - Naphthylazo) -7 - Nitronaphthalene - 1 - Sulphonate?
Sodium-3-hydroxy-4- (2-hydroxy-1-naphthyl azo) -7-nitro-naphthalene-1-sulfonate This material has a distinct color state. It is often powdery, colorful or plain, and has a different style. In terms of solubility, it has a certain affinity for water and is soluble in it, forming a uniform liquid phase. This is due to the strong hydrophilicity of the sulfonic acid group in the molecule, which allows it to melt in the aqueous medium.
In terms of stability, under normal temperature, it is still stable, but when it encounters strong acids and bases, the structure is variable and chemical reactions occur. When the temperature rises, the stability also decreases, or decomposes or deteriorates. And it is sensitive to light, and its structure and properties gradually change if it is illuminated for a long time.
From the perspective of spectral characteristics, because it contains chromophore groups such as azo and naphthalene rings, it can show unique absorption peaks under specific wavelengths of light, which can be used for qualitative and quantitative determination in the analytical field. The physical properties of this substance are of great significance in many industrial and scientific research fields, such as printing and dyeing, which can be used as dyes; in analytical chemistry, it is an important analytical reagent.
What is the synthesis of Sodium 3 - Hydroxy - 4 - (2 - Hydroxy - 1 - Naphthylazo) -7 - Nitronaphthalene - 1 - Sulphonate?
To prepare Sodium + 3 - Hydroxy - 4- (2 - Hydroxy - 1 - Naphthylazo) -7 - Nitronaphthalene - 1 - Sulphonate, the method is as follows:
First take an appropriate amount of 2 - hydroxy - 1 - naphthylamine, in a suitable reactor, moderate dissolution in dilute acid solution, and then slowly add an appropriate amount of sodium nitrite solution, control the temperature in the low temperature range, about 0 - 5 degrees Celsius, diazotization reaction. During this period, close attention should be paid to the reaction process, and the reaction endpoint should be detected with starch-potassium iodide test paper. When the test paper turns blue and the color is stable, the diazotization reaction is completed.
Take another appropriate amount of 3-hydroxy-7-nitro-1-naphthalenesulfonic acid, place it in another container, dissolve it in an appropriate amount of alkaline solution, and adjust the pH value of the solution to a suitable range, between about 8-9.
After the diazotization reaction is completed, slowly drop the diazonium salt solution into the prepared 3-hydroxy-7-nitro-1-naphthalenesulfonic acid alkaline solution under stirring. The rate of dropwise addition should not be too fast to avoid the reaction being too violent. After the dropwise addition is completed, continue to stir the reaction for a period of time to make the reaction fully proceed. The temperature of this process also needs to be controlled, roughly maintained at 10-15 degrees Celsius.
After the reaction is completed, an appropriate amount of table salt is added to the reaction system to promote the precipitation of the product. Then the filtration operation is carried out, the filter cake is collected, and the filter cake is washed with an appropriate amount of cold water to remove impurities. Finally, the washed filter cake is dried to obtain Sodium + 3 - Hydroxy - 4 - (2 - Hydroxy - 1 - Naphthylazo) -7 - Nitronaphthalene - 1 - Sulphonate product. The whole process needs to pay attention to the precise control of the reaction conditions and the specifications of each step to obtain a pure product.
