2-Aminophenol-4-sulfonic acid, its preparation method, through the ages, there are many wonderful recipes. In the past, the production method first sulfonated phenol, using sulfuric acid as the sulfonating agent, at a specific temperature and time, the phenol was converted into p-hydroxybenzenesulfonic acid. Then, nitric acid and other nitrating agents were used to nitrate it to obtain 2-nitro-4-hydroxybenzenesulfonic acid. After the action of iron powder, sulfide base and other reducing agents, the nitro group was reduced to an amino group, and finally 2-aminophenol-4-sulfonic acid was obtained.
However, the ancient method or drawbacks, such as iron powder reduction, produced a large amount of iron mud, polluted the environment, and the product separation was complicated. Today's production method is gradually improving. Catalytic hydrogenation and reduction is the main way, and suitable catalysts, such as supported metal catalysts, are used to convert nitro hydrogenation to amino groups under mild conditions. This way is clean and efficient, the product is easy to separate, and the quality is also excellent.

What are the Physical Properties of 2-Amino Phenol-4-Sulphonic Acid?

2-Aminophenol-4-sulfonic acid is an organic compound. It has unique physical properties and is hereby described by you.
Looking at its appearance, it is often white to light gray crystalline powder, fine and uniform. It is quite stable at room temperature and pressure, which makes it able to maintain its inherent chemical structure under normal storage conditions and is not easy to change spontaneously.
When it comes to solubility, this substance is slightly soluble in cold water, but in hot water, the solubility increases significantly. This property is due to the difference in the interaction between molecular structure and water molecules. In cold water, the intermolecular force is strong, restricting its dispersion among water molecules; and the energy provided by hot water is enough to weaken this force, causing more molecules to combine with water and dissolve.
The melting point of 2-aminophenol-4-sulfonic acid is also an important physical property. Its melting point is in a specific temperature range. At this temperature, the substance changes from a solid state to a liquid state, and the molecular arrangement changes from an ordered lattice structure to a disordered liquid state. Accurate melting point data is essential for the identification and purification of the substance, because the presence of impurities often causes the melting point to change.
Furthermore, its density also has a certain value. Density reflects the mass per unit volume of a substance. This property has a significant impact in many practical applications. For example, in solution preparation, reaction system design, etc., its density needs to be considered to precisely control the amount of substance and the reaction process.
In addition, the compound may have a certain odor. Although it is not strong and pungent, it is also part of its physical properties and can be used as a reference for sensory recognition.
In summary, the physical properties of 2-aminophenol-4-sulfonic acid, such as appearance, solubility, melting point, density and odor, are interrelated and jointly determine its behavior and characteristics in the chemical field and related industrial applications.

How is the price trend of 2-Amino Phenol-4-Sulphonic Acid in the market?

2 - Amino + Phenol - 4 - Sulphonic + Acid, that is, 2 - aminophenol - 4 - sulfonic acid. As for the market price trend, I will describe it in the style of "Tiangong Kaiwu".
The price of various chemicals in Guanfu Chemical Industry often changes with various reasons, and 2 - aminophenol - 4 - sulfonic acid is also inseparable. In the past, the price of its price moved, either due to the abundance of raw materials, or the quality of the process, or the deficiency of supply and demand.
If the raw material, the production of this acid, requires all the materials, if its source is wide and the price is flat, the production cost of this acid will be low, and the price will also drop. On the contrary, if the raw material is scarce, if there are many people who ask for it, the price will rise.
The way of craftsmanship is also about the price. Make good use of the new method and meticulous work, the production efficiency is high, the quality is also excellent, and the price may rise steadily. If the process is outdated, the yield is low, and the cost is high, the price will not be good.
As for supply and demand, the market wants prosperity, and the production cannot be given, the price will rise. If there is too much demand for production, the stock of goods will be in the market, and the price will fall.
In recent years, looking at the market, the situation of raw materials has changed from time to time, the process has gradually changed, and the state of supply and demand is not constant. Therefore, the price of 2-aminophenol-4-sulfonic acid may rise or fall, which is difficult to determine. Sometimes due to abundant raw materials and advanced technology, the price is on the decline; sometimes the demand is booming, the raw materials are tight, and the price rises again.
However, if you want to know the exact price trend, you still need to carefully observe the market situation, study the change of raw materials, review the change of technology, and measure the number of supply and demand before you can get a rough outline. The market situation is like a flow, changing rapidly. Only by discerning the movements of prices can you have insight and be good at planning.

2-Amino Phenol-4-Sulphonic Acid Quality Standards

For 2-aminophenol-4-sulfonic acid, its Quality Standards are related to many aspects. The appearance of this substance is often white to light gray crystalline powder, and whether the color and morphology are uniform or not is an important consideration. Purity is the key. High purity has few impurities, and it can be fully effective in various applications. Usually, the purity is required to reach a specific high standard, such as not less than a certain exact ratio.
In addition to its solubility, it should be suitable for solubility in water or specific organic solvents to meet different process requirements. In terms of pH, the pH value of its solution must also be maintained within a certain range, which has a great impact on its stability and reactivity.
In addition, the content of heavy metals, such as lead and mercury, must be strictly controlled at a very low level to prevent harm to the subsequent use process and the environment. The moisture content cannot be ignored. Excessive moisture may cause deliquescence, which affects the quality and storage period, so it should be limited to a reasonable range.
And its melting point, boiling point and other physical properties are also involved in Quality Standards. Accurate values can verify the quality and consistency of its quality. These Quality Standards are the fundamental criteria for ensuring product quality and performance when applying 2-aminophenol-4-sulfonic acid in many fields such as chemicals and pharmaceuticals.
