Aminonaphtalenedisulfonic acid monosodium salt; what are the physical properties of 95%
Monosodium salt of amino naphthalene disulfonic acid, with a content of 95%, has many physical properties. Its color state is often solid, mostly powdery or crystalline, delicate and regular shape, which is caused by the orderly arrangement of its molecules.
This substance has unique solubility and has a certain solubility in water. Because the molecule contains polar groups, it can form hydrogen bonds and other interactions with water molecules. However, the solubility is restricted by temperature. When the temperature increases, the solubility increases.
The melting point is also a key physical property and has a specific melting point. At the melting point temperature, the substance changes from solid to liquid state. This temperature reflects the strength of the intermolecular force. If the force is strong, the melting point is high.
In terms of density, it is relatively large, because of its compact molecular structure and the mass of the substances contained in the unit volume. In addition, its stability is quite good. Under conventional conditions, the chemical properties are relatively stable, and it is not easy to spontaneously react with common substances. However, it encounters specific substances such as strong oxidizing agents, or reacts under special conditions such as high temperature and high pressure.
Its appearance and color may vary depending on the purity and type of impurities. If it is pure, it may be colorless and transparent, and if it contains impurities, it may be slightly yellow and other light colors. These physical properties are of great significance for its application in chemical, pharmaceutical and other fields, and determine its application scenarios and processing methods.
Aminonaphtalenedisulfonic acid monosodium salt; what are the characteristics of 95% chemistry
Aminonaphthalene disulfonic acid monosodium salt, the content of 95%, its chemical properties are quite unique. This substance is an organic compound, containing amino groups, sulfonic acid groups and sodium ions, and its characteristics are derived from the interaction of these groups.
First of all, solubility is mentioned. Because of its sulfonic acid group, it exhibits good solubility in water and can form a stable and uniform solution. This property is extremely critical in many industrial applications, such as the manufacture of dyes and auxiliaries, which can efficiently disperse the substance in the reaction system and promote the smooth progress of the reaction.
Then again, acidic, sulfonic acid groups give it acidic properties, which can neutralize and react with bases to form corresponding salts. This property plays a significant role in regulating the pH of the reaction system. In a specific chemical reaction, the pH value of the system is precisely controlled by controlling its dosage to ensure that the reaction unfolds in the expected direction.
Stability is also an important property. Under normal conditions, the structure of the substance is relatively stable and can be stored for a long time without significant decomposition or deterioration. However, under extreme conditions such as strong oxidizing agents or high temperatures, the structure will be damaged and the properties will change accordingly.
Its reactivity is also worthy of attention. Amino groups can participate in a variety of reactions, such as acylation with acyl chloride, acid anhydride, etc., to synthesize various derivatives and expand their application range in different fields.
Aminonaphthalene disulfonic acid monosodium salt, 95% content, with its unique chemical properties, plays an important role in many fields such as chemical industry and materials, and provides an indispensable basic raw material for the development of related industries.
Aminonaphtalenedisulfonic acid monosodium salt; 95% What is the common production method
Aminonaphthalene disulfonic acid monosodium salt, the content is 95%. The common preparation method is as follows:
First, naphthalene is used as the starting material. Naphthalene can be sulfonated to introduce a sulfonic acid group. Under specific temperature and reaction conditions, naphthalene interacts with sulfuric acid, and the sulfonation ability of sulfuric acid prompts the hydrogen atom on the naphthalene ring to be replaced by a sulfonic acid group. This step requires precise control of temperature and sulfuric acid concentration. If the temperature is too high or the sulfuric acid concentration is improper, it is easy to cause excessive sulfonation or the formation of isomers, which affects the purity of the product.
Subsequently, on the basis of the sulfonated product, a nitration reaction is carried out. Select a suitable nitrification reagent, such as mixed acid (a mixture of nitric acid and sulfuric acid), The key to this step is to control the reaction conditions to ensure that the nitro group is introduced in the expected position, while avoiding excessive nitrification and preventing side reactions.
Next, the nitro group is reduced to an amino group. Reducing agents such as iron powder and sodium sulfide can be used to gradually convert the nitro group into an amino group in a suitable medium. This reduction step requires attention to the control of the reaction rate and the degree of reaction to prevent excessive reduction or other side reactions.
Finally, the product is neutralized to form a salt. Using basic substances such as sodium hydroxide, react with the sulfonic acid group in the product to form the monosodium salt of naphthalene disulfonic acid. After the reaction is completed, a series of separation and purification methods, such as crystallization, filtration, drying, etc., are used to obtain the monosodium salt of naphthalene disulfonic acid with a purity of 95%. Throughout the preparation process, each step is closely connected, and the reaction conditions need to be carefully adjusted to ensure product quality and yield.
Aminonaphtalenedisulfonic acid monosodium salt; what is the price range of 95% on the market
Nowadays, there are monosodium salts of aminonaphthalene disulfonic acid with a purity of 95%. It is difficult to judge the price range in the market. The price of these chemical raw materials often varies with many factors, just like the interaction of time, geographical location and personnel.
Looking at the past, the price of chemical industry varies depending on the abundance of raw materials, the pros and cons of technology, and the balance of supply and demand. If the raw materials are widely distributed and easy to recover, the cost will be reduced due to the improvement of the process, and the price will decrease due to the lack of demand. On the contrary, if the raw materials are scarce, the process is complicated, and there are many seekers, the price will rise.
Monosodium salt of aminonaphthalene disulfonic acid is used in many fields, such as dyes and medicine. Its price may fluctuate due to the rise and fall of various industries. The dye industry is prosperous, and the demand for it increases, and the price is also high; the pharmaceutical industry is in the doldrums, and there are few people who want it, and the price may drop.
And the market conditions change like the situation, the international situation, policies and decrees can affect its price. Therefore, in order to determine its price range in the market, it is necessary to carefully consider the current raw material prices, process conditions, supply and demand conditions, and market dynamics to obtain a more accurate number. However, at this moment, it is difficult to determine its specific price range based on the information given.
