The production method of 9,10-dihydro-3,4-dihydroxy-9,10-dioxo-2-anthracenesulfonic acid, sodium salt, is a very important chemical preparation technology. In the past, its preparation was often followed by ancient methods.
First take anthraquinones as the base, and use sulfuric acid, fuming sulfuric acid, etc. as sulfonation reagents to carry out the sulfonation method. At a suitable temperature and duration, a sulfonic acid group is introduced on the anthraquinone molecule. However, this step requires strict observation of the reaction process, and temperature control is very critical to prevent excessive sulfonation.
Then, by oxidation, strong oxidants, such as potassium permanganate, potassium dichromate, etc., are used to oxidize the groups at specific positions to obtain the structure of 9,10-dioxo. This process also requires careful adjustment of the reaction conditions, taking into account the degree of oxidation, so as to avoid impurity of the product. After
, hydroxyl groups are introduced, which are often treated with alkali solution, or specific nucleophiles are used to make a substitution reaction at a specific position and introduce hydroxyl groups. The ratio of reagents and the acid and base of the reaction environment all affect the accuracy of hydroxyl group introduction.
As for the formation of sodium salts, basic substances such as sodium hydroxide react with the obtained acid, and the acid-base neutralization is obtained to obtain sodium salts. After separation and purification, such as crystallization, filtration, washing, etc., a pure 9,10-dihydro-3,4-dihydroxy-9,10-dioxo-2-anthracenesulfonic acid and sodium salt are obtained.
Although this ancient method can be prepared, there are many drawbacks, such as complicated reaction steps, many side reactions, difficulty in product separation, and some reagents are highly corrosive and unfriendly to the environment. Today's research, multi-directional green and high-efficiency method exploration, hopes to optimize the production technology of this substance.

The sodium salt of 9,10-dihydro-3,4-dihydroxy-9,10-dioxo-2-anthracenesulfonic acid is a rather special compound. Its physical properties are unique. The appearance of this sodium salt is often powdery, as fine as smoke and dust, and as light as a feather. The color is white as snow, just like the snow that falls at the beginning of winter, pure and free of variegation.
Looking at its solubility, it can quietly dissolve in water, just like ice melting in water, invisible, forming a uniform and transparent solution, like water, but contains unique chemical activity. However, in some organic solvents, such as ether, petroleum ether, etc., it is difficult to dissolve, just like the incompatibility of oil and water, and the boundaries between the two are clear.
When it comes to melting point, the melting point of this sodium salt is quite high, and it needs a high temperature of fire to cause it to melt. When subjected to a hot topic, it softens slightly at first, and then gradually turns into a liquid state, just like steel in a high-temperature furnace, and finally becomes a hot flow. The stability of this hot topic makes it stable in many high-temperature environments, and it can not easily decompose or deform. It is like a strong fortress that can resist the invasion of high temperature.
Its density is slightly different from that of common salts. The density is moderate, neither frivolous nor heavy as lead. Placed in the hand, it can feel its unique weight, both realistic and not too heavy, as if to find a delicate balance between weight and weight. This physical property is also closely related to its unique chemical structure, which together constitute the unique property system of this compound.
