Nabiphenyl disodium salts may play a role in the finishing process after leather tanning, improving the gloss, feel and water resistance of the leather surface and enhancing the quality of leather products.
Is the production process of 3,3 '- ((1,1' -biphenyl) -4,4 '-diylbis (azo)) bis (7-amino-4-hydroxy-2-naphthalenesulfonate disodium salt) complex?
The compound mentioned by Guan Fu is named 3,3 '- ((1,1' -binaphthalene) -4,4 '-diyl bis (carbonyl)) bis (7-amino-4-methyl-2-benzofuranic acid), which is involved in the field of organic synthesis. Its preparation process is really complicated.
To make this compound, the choice of starting materials is very critical, and it is often based on binaphthalene compounds, which can be obtained through multi-step reactions. The first step involves the functionalization of binaphthalene derivatives, and the introduction of carbonyl and other functional groups at specific positions under suitable reaction conditions. This step requires precise temperature control and time control, and strict requirements on the purity and dosage of the reaction reagents. If there is a slight difference, side reactions will multiply and the product will be impure.
Subsequently, the construction of the benzofuranic acid part is also difficult. It is necessary to use appropriate raw materials and undergo a series of reactions such as condensation and cyclization to obtain the structure of benzofuranic acid containing specific substituents. The stereochemistry and regioselectivity of each step of the reaction need to be carefully controlled, otherwise the configuration and activity of the final product will be affected.
Furthermore, the part of the binaphthalene is spliced with the part of benzofuranic acid, and this step is the core of the synthesis. It is necessary to find a suitable coupling reaction, and choose a high-efficiency catalyst and ligand to promote the precise connection of the two, while avoiding unnecessary side reactions. The pH of the reaction system, solvent properties and many other factors have a great impact on the reaction process and product yield.
After each step of the reaction is completed, the separation and purification of the product is not easy. It is often necessary to comprehensively use column chromatography, recrystallization and other means to remove impurities one by one to obtain high-purity target products.
In summary, the production process of 3,3 '- ((1,1' -binaphthalene) -4,4 '-diylbis (carbonyl)) bis (7-amino-4-methyl-2-benzofuranic acid) is complex, and it has extremely high requirements in terms of reaction conditions, reagent purity, and operation skills, which is a major challenge in the field of organic synthesis.
2-Naphthalenesulfonic acid, 3,3 '- ((1,1' -biphenyl) -4,4 '-diylbis (azo)) bis (7-amino-4-hydroxy-, disodium salt) What are the special precautions during storage and transportation?
2-% thiazoleic acid, 3,3 '- ((1,1' -biphenyl) -4,4 '-diyl bis (carbonyl)) bis (7-hydroxy-4-methyl-, disodium salt) This compound should pay attention to the following things during storage and transportation:
First, because its chemical structure contains thiazoleic acid and specific biscarbonyl biphenyl derivatives and sodium salts, it is extremely sensitive to temperature and humidity. High temperature can easily cause changes in the molecular structure of the compound, or cause decomposition reactions, so the storage temperature should be controlled in a cool range, usually 2-8 ° C. If the humidity is too high, the sodium salt is partially deliquescent, which affects the purity and stability of the compound. The ambient humidity should be maintained at 40% - 60%.
Second, the compound contains active groups, which are easy to react with oxidants and reducing agents. When storing, it is necessary to avoid co-storage and co-transportation with such substances to prevent dangerous chemical reactions that threaten transportation and storage safety. For example, it should not be placed in the same place as peroxides and metal hydrides.
Third, the transportation process needs to ensure that the packaging is intact. If this compound leaks, it will not only cause its own losses, but also may pollute the environment due to its special composition. The packaging should be made of high-quality, chemically resistant materials, such as specially treated plastic containers or glass containers, and sealed to ensure that there is no risk of leakage during transportation.
Fourth, operators need to take protective measures. Because its ingredients have certain chemical activity, or irritate human skin, respiratory tract, etc. When exposed to this compound, appropriate protective gloves, masks and goggles should be worn to prevent direct contact and inhalation to ensure personal safety.
