This is the chemical structure of disodium-9,10-dioxo-9,10-dihydroanthracene-2,7-disulfonate. Its core is the parent nucleus of anthracene, which is an aromatic hydrocarbon with tricyclic fused, which is very important in the field of organic chemistry. In this compound, the carbon atoms at positions 9 and 10 of anthracene are each connected with an oxygen atom by double bonds, which is the structural feature of 9,10-dioxo. And at positions 2 and 7 of anthracene, a sulfonic acid group is introduced, which is connected by a sulfur atom and three oxygen atoms, and the sulfur atom is connected to the carbon atom. The sulfonic acid group is hydrophilic and can enhance the solubility of this compound in water. The hydrogen atoms on the two sulfonic acid groups of this compound are replaced by sodium ions, and then form a salt of disodium. With this structure, the compound has specific uses in dyes, pigments and other industries due to its unique electronic structure and hydrophilicity. For example, it can be used as an intermediate of dyes, and its structural characteristics endow dyes with specific colors and dyeing properties.

It seems to build a stable structure for paper, making the paper texture more uniform and tough. When tanning leather, it can be used as a tanning agent. The auxiliary tanning agent better combines with the leather fiber, making the leather soft and durable, like the toughness that gives leather life. In the manufacture of synthetic fibers, it can be used as a spinning oil component to reduce friction between fibers and ensure smooth spinning, just like paving a smooth path for fibers, allowing them to travel unimpeded during production. This substance plays a key role in many industrial fields and has made great contributions to product quality improvement.
Disodium 9,10 - Dioxo - 9,10 - Dihydroanthracene - 2,7 - Disulfonate What are the precautions during use?
For disodium 9,10-dioxo-9,10-dihydroanthracene-2,7-disulfonate, many matters need to be paid attention to when using it.
This agent is a chemical substance, and you must read its instructions carefully before using it. Know its properties, characteristics, uses, scope of application, etc. Check whether it is suitable for the operation you want to perform, and do not use it rashly.
When operating, protective gear is indispensable. Appropriate protective clothing should be worn to protect the body and skin from the erosion of the drug; wear protective gloves to avoid contact with the drug; wear a protective eye mask to prevent the drug from splashing into the eyes and damaging the eyes.
Use environment should also be paid attention to. Keep the place well ventilated. If used in a closed and poorly ventilated place, the volatile gas of the agent will accumulate, or cause poisoning. And keep away from fire and heat sources to prevent dangerous reactions of the agent when exposed to heat.
In terms of dosage, it should be strictly followed. If used too much, it may cause too much effect and cause accidents; if it is too little, it will be difficult to achieve the expected effect. Weighing must be accurate to ensure smooth operation.
Disposal after use should not be underestimated. Residual agents should not be discarded at will, and should be properly stored or disposed of in accordance with relevant regulations. The utensils used should be cleaned in time to prevent the residue of the agent from being left, which will be affected by the next use or cause damage to the utensils.
In addition, the user should have the corresponding knowledge and skills, and those who have not been trained should not operate without authorization. If you feel unwell or have an accident during operation, you should stop the operation immediately, seek medical treatment quickly, and inform the details of the medicament used for accurate rescue. In this way, Fang Guaranteed the safety of using disodium 9,10-dioxo-9,10-dihydroanthracene-2,7-disulfonate.
Disodium 9,10 - Dioxo - 9,10 - Dihydroanthracene - 2,7 - Disulfonate What is the production method?
The ancient method of preparing disodium 9,10-dioxo-9,10-dihydroanthracene-2,7-disulfonate follows the classical chemical synthesis path.
In the past, anthracene was often used as the initial material to prepare this compound. The anthracene is first sulfonated and co-heated with sulfuric acid and other sulfonating reagents under specific conditions. In the structure of anthracene, the hydrogen atom at a specific position is replaced by a sulfonic acid group (-SO 🥰 H) due to the reaction conditions to form anthracene disulfonic acid intermediates. This reaction requires precise temperature control. If the temperature is too high or too low, the position and degree of sulfonic acid substitution can be affected, and then the purity and yield of the product can be affected.
The obtained anthracene disulfonic acid is further oxidized. Usually with strong oxidizing reagents, such as chromic acid or its salts, in appropriate solvents and reaction environments, the carbon atoms at positions 9,10 on the anthracycline are oxidized to form 9,10-dioxo-9,10-dihydroanthracene-2,7-disulfonic acid. This oxidation process also needs to be carefully regulated, because excessive oxidation may cause structural damage to the product.
Finally, 9,10-dioxo-9,10-dihydroanthracene-2,7-disulfonic acid reacts with an appropriate amount of alkali substances such as sodium hydroxide, and the hydrogen atom of the sulfonic acid group is replaced by sodium ions, resulting in disodium 9,10-dioxo-9,10-dihydroanthracene-2,7-disulfonate. In this reaction, the amount of base needs to be accurately calculated, and excess or insufficient can affect the composition and properties of the neutral salt of the product. Between each step, separation and purification operations, such as crystallization and extraction, are often required to remove impurities and obtain a pure target product.
Disodium 9,10 - Dioxo - 9,10 - Dihydroanthracene - 2,7 - What is the market price for Disulfonate?
I don't know what the market price is for "Disodium 9,10 - Dioxo - 9,10 - Dihydroanthracene - 2,7 - Disulfonate" as you said. This famous product may be a special material in the chemical industry, and its price may vary greatly due to quality, purity, and supply and demand.
In the market, if the demand for this product is strong and the supply is limited, the price will be high; on the contrary, if the supply exceeds the demand, the price will be lower. And its purity is also the key to pricing. High purity is often more expensive, and low purity is cheaper.
The place of production and the cost of transportation can also affect its price. For those who are transported from afar, the price may be higher than that of those who are produced nearby because of the freight. To know the exact market price, you need to check the place where the chemical materials are traded in detail, or consult the merchants and experts in the industry to get an accurate price. And the market is fickle, and the price also changes over time, which cannot be generalized.
