Is the chemical properties of 9,10-Dioxo-10-Dihydroanthracene-1-Sulfonic Acid Ammoniate (1:1) stable?
The chemical properties of 9,10-dioxo-9,10-dihydroanthracene-1-ammonium sulfonate (1:1) are relatively stable. In this compound, the sulfonic acid group binds to the ammonium ion in a specific ratio to form a stable structure.
From the perspective of molecular structure, the 9,10-dioxo-9,10-dihydroanthracene part is a rigid planar structure, which gives it a certain stability. The sulfonic acid group has strong hydrophilicity, which can enhance the solubility of the compound in polar solvents. Ammonium ions interact with the sulfonic acid group through ionic bonds to further stabilize the molecular structure.
Under common conditions, this compound can maintain its structural integrity without the intervention of extreme chemical reagents such as strong oxidants, strong acids or strong bases. In neutral or weak acid-base environments, its chemical properties can remain stable for a long time and are not prone to spontaneous chemical reactions.
However, it should be noted that in case of special conditions such as high temperature, strong oxidation or strong reduction, its structure may be affected. For example, under high temperature, it may trigger intramolecular rearrangement reactions; strong oxidants may attack anthracyclines or sulfonic acid groups, resulting in structural changes. However, in general laboratory and industrial operating environments, 9,10-dioxo-9,10-dihydroanthracene-1-ammonium sulfonate (1:1) usually maintains stable chemical properties as long as extreme conditions are avoided.
What is the synthesis method of 9,10-Dioxo-9,10-Dihydroanthracene-1-Sulfonic Acid Ammoniate (1:1)
The synthesis of 9,10-dioxo-9,10-dihydroanthracene-1-ammonium sulfonate (1:1) is a key research in the field of organic synthesis. The method is as follows:
First, anthracene is used as the starting material, and the anthracene is oxidized to react with a strong oxidant under appropriate reaction conditions. If chromic acid and other oxidants are selected, in an acidic medium such as sulfuric acid, the 9th and 10th carbon of anthracene are oxidized to form 9,10-dioxo-9,10-dihydroanthracene. This step requires strict control of temperature, oxidant dosage and other conditions. If the temperature is too high, it is easy to cause excessive oxidation and damage the yield and purity of the product. The sulfonation reaction of 9,10-dioxo-9,10-dihydroanthracene with fuming sulfuric acid is carried out. The concentration of sulfur trioxide in fuming sulfuric acid is quite high, which can effectively promote the introduction of sulfonic acid groups into the first position of anthracycline. This reaction needs to pay attention to the reaction time and temperature. If the time is too short, the sulfonation will be incomplete, if the time is too long or the temperature is too high, or the formation of polysulfonation by-products. After the sulfonation reaction, 9,10-dioxo-9,10-dihydroanthracene-1-sulfonic acid is obtained. At the end of
, 9,10-dioxo-9,10-dihydroanthracene-1-sulfonic acid is combined with ammonia to form 9,10-dioxo-9,10-dihydroanthracene-1-ammonium sulfonate (1:1). This neutralization reaction should be carried out under mild conditions to control the amount of ammonia introduced to prevent the ratio of ammonium salt from deviating from 1:1, which affects the structure and properties of the product. After a series of purification steps, such as crystallization and recrystallization, a high-purity product of 9,10-dioxo-9,10-dihydroanthracene-1-ammonium sulfonate (1:1) can be obtained.
9,10-Dioxo-9,10-Dihydroanthracene-1-Sulfonic Acid Ammoniate (1:1) What are the precautions when storing
9,10-Dioxo-9,10-dihydroanthracene-1-ammonium sulfonate (1:1), when storing, there are several ends that should be paid attention to.
First, this substance is quite sensitive to temperature and humidity. If it is in a high temperature environment, it is feared that its structure will change and cause different properties. It should be stored in a cool place, so that its temperature is constant between 15 and 25 degrees Celsius. As for humidity, it should be controlled at 40% to 60%. If the humidity is too high, it may cause deliquescence, which will damage its quality; if the humidity is too low, or cause it to lose water, it will also affect its properties.
Second, it is also essential to avoid light. This product is prone to photochemical reactions when exposed to light, or causes decomposition, losing its original properties. Therefore, it is appropriate to store it in a dark container and place it in a dark place to prevent light from disturbing it.
Third, isolation from other things should not be ignored. This ammonium sulfonate may react in contact with strong oxidants and strong bases, causing a dangerous appearance. Therefore, when storing, it should be placed separately from such things, separated by a considerable distance to prevent them from mixing and changing.
Fourth, the choice of container is also important. When using a closed and corrosion-resistant device to prevent it from communicating with the outside gas and causing deterioration, and to avoid the device from phase transformation and damage to its quality. Only by paying attention to everything in this way can the safety and integrity of 9,10-dioxo-9,10-dihydroanthracene-1-ammonium sulfonate (1:1) be maintained during storage.
