What are the physical properties of Disodium 2,2 '- [ (5,8-Dihydroxy-9,10-Dioxo-9,10-Dihydroanthracene-1, 4-Diyl) Diimino] Bis (5-Methylbenzenesulfonate)
This substance is called disodium 2,2 '- [ (5,8-dihydroxy-9,10-dioxo-9,10-dihydroanthracene-1,4-diyl) diimino] bis (5-methylbenzene sulfonate). Its physical properties are as follows:
This substance is often powdery or crystalline, and its color is mostly light yellow to brown. In terms of solubility, it exhibits good solubility in water. By virtue of the affinity of the sulfonic acid group in the molecule and the water molecule, it can be uniformly dispersed to form a stable solution. This property makes it excellent in many aqueous system applications. However, in organic solvents such as ethanol and ether, the solubility is poor, because the molecular polarity is quite different from that of organic solvents.
In terms of melting point, it has a specific melting point range determined by measurement. This value is very critical to its state stability under specific temperature conditions. When heated to the melting point, it will change from a solid state to a liquid state. This characteristic is quite important in the temperature control of material processing and synthesis processes.
The appearance is stable. Under normal environmental conditions, if there is no external chemical interference and extreme environmental influence, it can maintain the initial shape and structure for a long time, and the chemical properties are relatively stable, which provides convenience for its storage and transportation. However, under extreme conditions such as specific chemical environments or high temperature and high pressure, the molecular structure will change, which in turn affects the physical properties.
What is the preparation method of Disodium 2,2 '- [ (5,8-Dihydroxy-9,10-Dioxo-9,10-Dihydroanthracene-1, 4-Diyl) Diimino] Bis (5-Methylbenzenesulfonate)
The method of preparing disodium 2,2 '- [ (5,8-dihydroxy-9,10-dioxo-9,10-dihydroanthracene-1,4-diyl) diimino] bis (5-methylbenzene sulfonate) is as follows:
First take an appropriate amount of anthraquinone compound and use it as the starting material, which is the foundation of the reaction. In a specific reaction vessel, add this anthraquinone compound, and add a reagent containing specific functional groups such as hydroxyl groups and amino groups in an appropriate proportion. The dosage and ratio of this reagent need to be precisely controlled, and a slight difference will affect the purity and yield of the product.
Then, adjust the temperature and pH of the reaction system. The temperature should be maintained in a certain precise range, either slightly hot or low temperature, depending on the specific reaction mechanism. The pH also needs to be carefully regulated, and acid-base regulators can be used to make the reaction environment meet the needs of the reaction.
Then, the reaction is started, so that the material can fully react under the set conditions. During this process, molecules collide with each other, rearrange, break and form chemical bonds, and undergo complex chemical changes. During the reaction, the reaction process needs to be closely monitored, and the degree of reaction can be observed by means of thin-layer chromatography.
When the reaction reaches an appropriate stage, the product is separated and purified. First, the target product is initially separated by conventional means such as filtration and extraction. Subsequently, fine methods such as recrystallization and column chromatography are used to further purify the product, remove impurities, and improve the purity of the product.
In this way, after multiple processes and rigorous operation, high-purity disodium 2,2 '- [ (5,8-dihydroxy-9,10-dioxo-9,10-dihydroanthracene-1,4-diyl) diamino] bis (5-methylbenzene sulfonate) can be prepared.
