8-Amino-1-Naphthol-3, What are the physical properties of 6-Disulfonic Acid Monosodium Salt Monohydrate

8-Amino-1-naphthol-3,6-disulfonic acid monosodium salt monohydrate, this is an organic compound. Its physical properties are quite critical and are related to many fields of application.
When it comes to appearance, it usually appears as a white to off-white crystalline powder. This form is easy to store and use, and is easy to handle in many chemical processes.
In terms of solubility, the substance can exhibit certain solubility properties in water. Water can become a good solvent for it, and this property is of great significance when preparing solutions, performing chemical reactions, or as an ingredient in certain formulations. It can be dissolved in water, allowing it to be evenly dispersed in the system, which is conducive to participating in various chemical changes or performing its specific functions.
Melting point is also an important physical property. A clear melting point value provides a basis for its state transition during heating. At a specific temperature, the transition point from solid to liquid state plays a crucial role in controlling the production process and determining the processing temperature range. If the temperature is not properly controlled and too much higher than the melting point, it may lead to runaway material morphology and affect product quality; and if the temperature does not reach the melting point, some process operations based on its liquid characteristics cannot be realized.
In addition, its stability is also worthy of attention. Under normal conditions, it has a relatively stable chemical structure and is not prone to spontaneous violent chemical reactions. However, under the influence of specific environmental factors, such as high temperature, high humidity or contact with specific chemicals, stability may be challenged. Understanding its stability limits can help to rationally choose storage conditions and use scenarios to prevent deterioration of substances due to external factors, thereby ensuring the reliability of the quality and performance of products based on raw materials or ingredients.

8-Amino-1-Naphthol-3, 6-Disulfonic Acid Monosodium Salt Monohydrate is chemically stable?

8-Amino-1-naphthol-3,6-disulfonic acid monosodium salt monohydrate, this substance is stable in behavior?
This agent is stable in its properties under common sense. However, the properties of chemical substances often vary depending on the surrounding environment. If it is baked at high temperature, this agent may change. The energy of heat, the state of movable molecules, causes structural changes, or looks like decomposition. And it is near an open flame, and there are hidden dangers. Although it is not flammable, it will promote high temperature or cause unexpected.
And look at it in the wet and tidal environment, water is the medium for the transformation of all things, and the water molecules and the particles in the agent are in contact, or the state of their synthesis is changed. The intervention of water, or the process of hydrolysis, causes the composition to change.
Again, when it comes into contact with other substances, if it encounters strong oxidizing agents, such as permanganic acid and dichromic acid, the ability of oxidation can take away electrons in the agent, and the reaction will rise, causing a major change in the state. In case of strong reducing agents, there is also a risk of reaction, and the acceptance of electrons will make the structure more tensile.
In summary, 8-amino-1-naphthol-3,6-disulfonic acid monosodium salt monohydrate is generally stable in normal conditions, but in special conditions, such as high temperature, moisture, or with strong oxidation and reducing agents, it can cause changes in behavior. Be careful when using it, and pay attention to the surrounding environment to prevent accidents.

8-Amino-1-Naphthol-3, 6-Disulfonic Acid Monosodium Salt Monohydrate

The preparation method of 8-amino-1-naphthol-3,6-disulfonic acid monosodium salt monohydrate is not detailed in the ancient book "Tiangong Kaiwu", but it can be deduced according to the principles of ancient chemical industry.
First take the naphthalene as the base, and use the agent of nitrosulphur to prepare it according to its properties, so that the naphthalene is nitrified into nitronaphthalene. This step requires temperature control and control, and the amount of nitrosulphur should also be accurate, so that the nitro is just in the position of the naphthalene ring, which is the foundation for the subsequent reaction.
Nitronaphthalene has been obtained, using iron filings and acid as the medium, so that the nitro is also an amino group to form amin In this process, the purity of iron filings and the intensity of acid are all related to the success or failure of the reaction, so it should be carefully inspected.
Then, sulfonated aminonaphthalene with fuming sulfuric acid. Fuming sulfuric acid is strong in nature and is very hot during the reaction. It needs to be added slowly and stirred to make the sulfonyl group enter the 3,6 positions of aminonaphthalene to obtain 8-amino-1-naphthol-3,6-disulfonic acid.
Then neutralize it with soda ash or caustic soda to obtain the sodium salt of 8-amino-1-naphthol-3,6-disulfonic acid. At the time of operation, the amount of alkali should be moderate, with more damage and less neutralization.
Finally, in a suitable temperature and humidity environment, let it crystallize to obtain 8-amino-1-naphthol-3,6-disulfonic acid monosodium salt monohydrate containing crystalline water. Temperature, humidity, and crystallization time are all critical, and fine regulation is required to obtain pure products.

8-Amino-1-Naphthol-3, 6-Disulfonic Acid Monosodium Salt Monohydrate in the market price range

The price of 8-amino-1-naphthol-3,6-disulfonic acid monosodium salt monohydrate in the market is difficult to determine. The price of these chemical materials often varies for many reasons. First, the supply and demand of the market, if there are many people who want it, and there are few people who supply it, the price will rise; conversely, if the supply exceeds the demand, the price may drop. Second, the production is difficult and easy. If its preparation requires complicated methods and rare materials, the price will be high; if it is easier to make, the price may be slightly lower. Third, the price set by different producers varies depending on the quality of technology and the level of the original.
And looking at the past, the prices of all the things described in "Tiangong Kaiwu" changed with the world. The same is true of this 8-amino-1-naphthol-3,6-disulfonic acid monosodium salt monohydrate. Its price may range from a few yuan to a few tens of yuan per gram, or it may vary depending on the quantity. Those with large quantities may have a favorable price; those with small retail quantities may have a slightly higher price. Or because of the difference in land purchase, different places have different price regulations and transportation costs, so their prices are different. Therefore, if you want to know the exact price, you should consult the chemical material supplier and ask the price in detail to get a close and accurate number.
