2,7-Naphthalene disulfonic acid, 4-amino-5-hydroxy-3,6-bis [[4- [2- (sulfoxy) ethyl] sulfonyl] phenyl] azo] -, What are the physical properties of tetrasodium salts
2% 2C7-naphthalic acid, 4-hydroxy-5-fluoryl-3,6-bis [[4 - [[2 - (carboxyloxy) ethyl] carboxyphenyl] benzyl] carbonyl] -, nickel tetracarbonyl is an important metal organic compound. Its physical properties are as follows:
Nickel tetracarbonyl appears as a colorless volatile liquid at room temperature and pressure, emitting a gasoline-like odor. Its melting point is relatively low, about -25 ° C, which allows it to melt into a liquid at lower temperatures. The boiling point is also not high, about 43 ° C, indicating that it has good volatility.
Nickel tetracarbonyl has a higher density than water, about 1.32 g/cm ³. It is insoluble in water, but soluble in most organic solvents, such as benzene, carbon tetrachloride, ethanol, etc. This solubility characteristic is related to its molecular structure and the interaction of organic solvents.
From the perspective of stability, nickel tetracarbonyl is relatively stable at room temperature, but it is sensitive to heat and easily decomposes when heated to form nickel and carbon monoxide. And it can react with oxygen in air and has a certain oxidation sensitivity. In addition, nickel tetracarbonyl is a highly toxic substance, and its vapor can cause serious harm to the human body. The main ways to invade the human body are inhalation, ingestion, and percutaneous absorption. Therefore, extra caution is required during use and storage, and safety procedures are strictly followed.
2,7-Naphthalene disulfonic acid, 4-amino-5-hydroxy-3,6-bis [[4- [[2- (sulfoxy) ethyl] sulfonyl] phenyl] azo] -, What is the synthesis method of tetrasodium salt
"Tiangong Kaiwu" says: "All the skills in the world have their own methods, and the wonders of making things are in one mind." To make 2,7-naphthalenedioic acid, 4-hydroxy-5-fluoro-3,6-bis [[4- [[2- (carboxyloxy) ethyl] carboxyphenyl] benzyl] carbonyl] -, this tetracarboxyquinoxaline, the method is as follows:
The first suitable raw material needs to be carefully selected to check its purity and character. This is fundamental. With naphthalene as the initial substrate, the synthesis of the target product can be achieved through multiple and delicate reactions.
First carry out a specific substitution reaction on naphthalene. Under suitable reaction conditions, such as precise control of temperature, pressure, reaction time, and selection of appropriate catalysts, the required substituents are introduced at specific positions on the naphthalene ring to obtain key intermediates. This step requires caution, because the accuracy of the reaction determines the success or failure of the subsequent steps.
Then the intermediate is oxidized to convert the specific group into a carboxyl group, which is the key to the formation of the 2,7-naphthalic acid structure. During the oxidation process, factors such as the amount of oxidant and the pH of the reaction environment need to be strictly controlled. If there is a slight difference in the pool, it is easy to cause the product to be impure or the yield to be low.
As for the construction of 4-hydroxy-5-fluoryl-3,6-bis [[4- [[2- (carboxyloxy) ethyl] carboxyphenyl] benzyl] carbonyl] -structure, a multi-step organic synthesis strategy is required, including halogenation, condensation, substitution and many other reactions. During each step of the reaction, the intermediate needs to be properly handled to prevent its deterioration or unnecessary side reactions.
After each step of the reaction, the product should be separated and purified to maintain its purity. Methods such as recrystallization and column chromatography can be used to remove its impurities and keep its essence. In this way, the compound of tetracarboxyquinoxaline can be successfully synthesized by carefully operating in multiple steps, strictly following the reaction rules, and controlling various conditions.
