3,4 - Dihydroxy - 9,10 - Dioxo - 2 - Anthracenesulfonic Acid, Sodium Salt

3%2C4+-+Dihydroxy+-+9%2C10+-+Dioxo+-+2+-+Anthracenesulfonic+Acid%2C+Sodium+Salt that is, the sodium salt of 3,4-dihydroxy-9,10-dioxo-2-anthraquinone sulfonic acid. The preparation methods of this substance have been different throughout the ages, and the methods are also different due to different raw materials and uses.
In the past, this sodium salt was mostly prepared with anthraquinone as the starting material. First sulfonate anthraquinone, add an appropriate amount of sulfuric acid and other sulfonating reagents in a specific reactor, and control it at an appropriate temperature and duration. The anthraquinone is introduced into the sulfonic acid group at the second position to obtain 2-anthracenesulfonic acid. Thereafter, the steps of oxidation and hydroxylation of 2-anthracenesulfonic acid are carried out. At the time of oxidation, a strong oxidant, such as chromic acid, is often used to oxidize the 9,10 positions of anthracycline to carbonyl to form 9,10-dioxo-2-anthracenesulfonic acid. Then a suitable hydroxylation reagent, such as alkali metal hydroxide, is used to introduce hydroxyl groups at the 3,4 positions under appropriate conditions to obtain 3,4-dioxy-9,10-dioxy-2-anthracenesulfonic acid. Finally, this acid is reacted with a base such as sodium hydroxide, and the acid-base is neutralized to obtain a sodium salt of 3,4-dioxy-9,10-dioxy-2-anthracenesulfonic acid.
However, this method has many drawbacks, such as the use of oxidants such as chromic acid, the separation of products is complicated, and the waste of chromium is easy to pollute the environment. Therefore, there are also new ways to explore in later generations. There are green chemistry-oriented catalytic oxidation methods. Select specific catalysts, such as metal complexes, to achieve the oxidation and hydroxylation of anthraquinone under relatively mild conditions, reduce the generation of waste, and improve the atomic economy of the reaction. Or explore new raw materials, such as anthracene derivatives containing specific substituents as the starting point, simplify the reaction steps, and optimize the preparation process. All of these are methods for preparing this sodium salt, each with its own advantages and disadvantages, and need to be used according to the actual situation.

3,4 - Dihydroxy - 9,10 - Dioxo - 2 - Anthracenesulfonic Acid, Sodium Salt What are the physical and chemical properties

3%2C4+-+Dihydroxy+-+9%2C10+-+Dioxo+-+2+-+Anthracenesulfonic+Acid%2C+Sodium+Salt is the sodium salt of 3,4-dihydroxy-9,10-dioxo-2-anthracenesulfonic acid. This substance has the following physical and chemical properties:
In terms of view, it is usually in solid form, or in powder form, white or near-white in color, and the fine particles are gathered in piles, and the quality is fine. Its solubility is quite special, and it is soluble in water, just like a salt fused into water. The water molecules interact with the sodium salt, and the ions are dispersed in the water to form a uniform liquid phase. This property makes it important in the reaction or application of aqueous solution systems.
In terms of stability, the properties of the sodium salt are still stable under normal temperature and humidity environments, but not under extreme conditions. When the temperature is high, the chemical bonds within the molecule can be excited, or cause structural changes and decomposition, resulting in different products. The environment of strong acid and alkali also affects it, because it is a sodium salt, acid-base changes or interferes with ion balance, causing chemical properties to change.
Its melting point is also an important physical property. At a certain temperature, the lattice structure of the substance disintegrates and gradually melts from a solid state to a liquid state. This temperature is its melting point. The exact value of the melting point is closely related to the purity of the substance. The melting point of the pure product is fixed. If it contains impurities, the melting point may decrease and the melting range becomes wider.
The sodium salt is used in the chemical field. Due to the structure of hydroxyl groups, carbonyl groups and sulfonic acid groups, it has various chemical activities. Hydroxyl groups can participate in esterification, oxidation and other reactions, carbonyl groups can perform nucleophilic addition, and sulfonic acid groups make molecules have good water solubility and ionic characteristics, which are widely used in organic synthesis, dye preparation and other industries.

3,4 - Dihydroxy - 9,10 - Dioxo - 2 - Anthracenesulfonic Acid, Sodium Salt What is the approximate price in the market

3%2C4+-+Dihydroxy+-+9%2C10+-+Dioxo+-+2+-+Anthracenesulfonic+Acid%2C+Sodium+Salt, that is, the sodium salt of 3,4-dihydroxy-9,10-dioxo-2-anthracenesulfonic acid. However, its price in the market is roughly geometric, and it is difficult to determine. The price of this product often changes for many reasons.
The abundance of its raw materials is a major reason. If the raw materials for making this sodium salt are easily available and widely available, the price may be leveled; if the raw materials are rare and difficult to harvest, the price will be high. Furthermore, the preparation method is also important. Convenient and exquisite methods can reduce costs, and the price will be low; if the preparation is cumbersome and time-consuming, the price will be high.
There is supply and demand in the market. If there are many people who need it, the demand will exceed the supply, and the price will rise; if the market hoards up and the supply exceeds the demand, the price will fall. And the difference in origin also has an impact. Different places have different prices due to taxes, freight, etc.
Although it is difficult to determine its price, it is based on the examples of various chemical products in the past. If it is widely used, it is indispensable in the chemical industry, printing and dyeing, etc., and it is not easy to prepare, its price may not be cheap, or to tens of gold per unit, or even more than 100 gold. If the use is limited, it is not difficult to prepare, and the price may be slightly lower, or to more than ten gold per unit. These are all speculative numbers. To know the exact price, you need to consult the supplier of chemical materials or check the market report to obtain the true price.
