What are the physical properties of 4-Acetamido-2-Aminobenzenesulfonic Acid?
4-Acetamido-2-aminobenzenesulfonic acid, in the shape of white or off-white crystalline powder. This substance is slightly soluble in water, slightly more soluble in hot water, and insoluble in organic solvents such as ethanol and ether.
Looking at its physical properties, the melting point is quite critical, between about 280 ° C and 290 ° C. When heated, a phase transition will occur in this temperature range. Its stability is also an important physical property. Under normal environmental conditions, its properties are relatively stable, but if it is exposed to extreme environments such as strong acids, strong bases, or high temperatures and high humidity, chemical reactions may occur, causing changes in its structure and properties.
Re-discussion of its solubility, because the molecule contains both polar sulfonic acid groups, acetamide groups and amino groups, it has a certain solubility in water, but it is not very soluble. Polar organic solvents may interact with it to a certain extent, but due to the complex molecular structure, the degree of solubility is limited. This solubility characteristic has a great influence on the separation, purification and reaction medium selection when it is used in chemical and pharmaceutical fields.
In addition, the physical properties of 4-acetamido-2-aminobenzenesulfonic acid, such as density and particle size, are also closely related to the application. The density is related to the measurement of the amount of material and the ratio of the reaction system, and the particle size affects its dispersion and fluidity, which is of great significance in the preparation of preparations and powder processing. In short, its various physical properties lay the foundation for the rational application of this substance. When applying in different fields, it is necessary to properly select the process conditions and treatment methods according to its physical properties.
4-Acetamido-2-Aminobenzenesulfonic Acid is chemically stable?
The chemical properties of 4-acetamido-2-aminobenzenesulfonic acid are stable under normal temperature and pressure. The molecular structure of this substance contains acetamido, amino and sulfonic acid groups. The presence of acetamido groups makes the molecule stable to a certain extent, because its amide bonds can form intramolecular or intermolecular hydrogen bonds, which enhances the regularity of the molecule.
Amino groups are basic groups with electron-giving effects and can participate in various chemical reactions, such as salting with acids, or acylating with acyl halides, acid anhydrides, etc. Sulfonic acid groups are strongly acidic groups, which can be completely ionized in water, giving the substance good water solubility. Due to the strong hydrophilicity of the sulfonic acid group, 4-acetamido-2-aminobenzenesulfonic acid is easily soluble in water, and its aqueous solution is acidic.
However, its stability is not absolute. In case of high temperature, open flame or strong oxidant, there is a risk of chemical reaction. At high temperature, the chemical bonds in the molecule may break due to sufficient energy, triggering decomposition reactions. Strong oxidants can oxidize certain groups in the molecule, causing changes in its structure and properties.
When storing and using 4-acetamido-2-aminobenzenesulfonic acid, it should be placed in a cool, dry and well-ventilated place, away from fire, heat sources and strong oxidants, in order to maintain its chemical stability and avoid accidental chemical reactions.
What is the production process of 4-Acetamido-2-Aminobenzenesulfonic Acid?
4-Acetamido-2-aminobenzenesulfonic acid, the preparation process is as follows:
First take an appropriate amount of aniline, place it in a reaction kettle, add an appropriate amount of glacial acetic acid, and carry out acetylation reaction at a certain temperature. In this process, glacial acetic acid reacts with aniline, and the amino hydrogen of aniline is replaced by acetyl to generate acetaniline. The reaction requires strict control of temperature and reaction time to ensure that the reaction is sufficient and the product purity is high.
Next, take out the generated acetaniline, put it in another reaction vessel, and add concentrated sulfuric acid. Under specific conditions, concentrated sulfuric acid and acetaniline undergo a sulfonation reaction. The sulfonic acid group in concentrated sulfuric acid replaces the hydrogen atom on the acetylaniline ring, and mainly substitutes at the ortho position of the amino group, thereby generating 4-acetamido-2-aminobenzenesulfonic acid. The reaction process needs to be closely monitored to prevent side reactions from occurring.
After the reaction is completed, the reaction product is post-processed. The reaction liquid is first poured into a large amount of ice water to precipitate the product. Then the solid product is separated from the liquid by filtration means. Then the solid product is washed with an appropriate amount of cold water to remove impurities attached to the surface. Finally, it is dried to obtain a relatively pure 4-acetamido-2-aminobenzenesulfonic acid product.
The whole preparation process needs to be precisely controlled by factors such as temperature, reaction time, and reactant ratio in order to prepare high-quality 4-acetamido-2-aminobenzenesulfonic acid.
What is the price range of 4-Acetamido-2-Aminobenzenesulfonic Acid in the market?
The price of 4-acetamido-2-aminobenzenesulfonic acid in the market is difficult to determine. The range of its price varies due to many reasons.
Looking back at the past, the price of chemical raw materials often changed with supply and demand, the price of raw materials, political regulations, and technological progress. If there are many people seeking this product, and the supply is small, its price will rise; on the contrary, if the supply exceeds the demand, the price may drop.
The price of raw materials is also the main reason. If the price of raw materials required to make this acid is high, the price of finished products will also increase; the price of raw materials will fall, and the price of finished products may decline.
The regulations of the political constitution also have an impact on its price. The policy of environmental protection is becoming stricter, and factories need to increase investment to comply with regulations. This will inevitably lead to higher costs, which in turn will change prices.
And technological progress may increase productivity, reduce costs, and also make prices vary. However, at this time, it is not easy to determine the accuracy of its inter-market price. It does not cover current supply and demand, raw material prices, etc. Basically speaking, in the past, the price of the market fluctuated in various price points due to differences in quality, quantity, and purchase time. Or when trading in small quantities, the price is slightly higher; if you buy in bulk, there may be a better price. Although it is difficult to determine the range of the price at this moment, various factors can help to detect the change in the price.
