What is the preparation method of 4,4-Dicarbox-2,2-biquinoline disodium salt

The method of preparing 4,4 '-dicarboxyl-2,2' -biquinoline disodium salt is to take 4,4 '-dimethyl-2,2' -biquinoline as the starting material. This compound can be obtained by a specific organic synthesis path, and its preparation process may involve multi-step reactions, such as condensation and cyclization of aromatic compounds, but this is not discussed in detail in this article.

After obtaining 4,4 '-dimethyl-2,2' -biquinoline, place it in a suitable reaction vessel and oxidize it with a strong oxidant. Commonly used oxidants, such as potassium permanganate or potassium dichromate, can be used for this reaction. The reaction must be carried out under appropriate reaction conditions, such as heating, stirring and an environment with suitable solvents. Dissolve 4,4 '-dimethyl-2,2' -biquinoline in a suitable solvent, such as organic solvents such as dichloromethane, N, N-dimethylformamide, etc., so that the reaction substrate is fully dispersed, which is conducive to the reaction. During the

oxidation reaction, the methyl group is gradually oxidized to the carboxyl group, thereby obtaining 4,4 '-dicarboxyl-2,2' -biquinoline. However, this product is not yet in the form of the target sodium salt, so further reaction is required. Mix 4,4 '-dicarboxyl-2,2' -biquinoline with an appropriate amount of sodium hydroxide solution, the carboxyl group and sodium hydroxide undergo neutralization reaction, and the hydrogen in the carboxyl group is replaced by sodium ions, thereby generating 4,4 '-dicarboxyl-2,2' -biquinoline disodium salt.

After the reaction is completed, the separation and purification of the product is also a key step. Conventional separation methods can be used, such as crystallization, extraction, column chromatography, etc. The crystallization method can take advantage of the difference in the solubility of the product in different solvents, by slowly cooling or adding bad solvents, the product can be crystallized and precipitated, and then filtered and washed to obtain a relatively pure 4,4 '-dicarboxyl-2,2' -biquinoline disodium salt. The extraction method is based on the different distribution coefficients of the product in different solvent phases, and a suitable extractant is selected to extract the product from the reaction mixture to a specific solvent phase, and then the product is separated by subsequent treatment. The column chromatography method uses the difference between the stationary phase and the mobile phase to separate the product and the impurities in the column. In this way, through a series of operations, a pure 4,4 '-dicarboxyl-2,2' -biquinoline disodium salt can be obtained.

What are the precautions for 4,4-Dicarbox-2,2-biquinoline disodium salt during use?

4% 2C4-dicarboxyl-2% 2C2-biquinoline disodium salt, when using, many things cannot be ignored.

First, the properties of this substance need to be carefully examined. It is in the state of sodium salt and has different solubility in different solvents. If it is soluble in water or appears to be slow to dissolve, it must be stirred patiently to promote uniform dissolution. If using organic solvents, such as ethanol, it is also necessary to pay attention to its mutual solubility. Do not mix it rashly to prevent precipitation and damage the effect of the drug.

Second, safety is of paramount importance. This substance may be irritating to the human body. If it touches the skin, rinse it with plenty of water as soon as possible; if it does not enter the eyes carefully, it is necessary to rinse it with an eye wash immediately and seek medical attention as soon as possible. Handle it in a well-ventilated place to avoid dust inhalation and damage to the respiratory system.

Third, the method of storage is related to quality. It should be placed in a cool, dry place, away from heat sources and light sources. If exposed to light for a long time, it may cause its structure to mutate and its efficacy will be impaired. And it should be separated from other chemicals to prevent their interaction and adverse reactions.

Fourth, accurate dosage is the key. Excessive use, or excessive reaction, will increase the cost, and may also introduce impurities; insufficient dosage, the effect will not meet expectations. Therefore, before use, when accurately calculated according to the experimental purpose and reaction system, in order to achieve the best effect.

When using 4% 2C4-dicarboxyl-2% 2C2-biquinoline disodium salt, caution should be taken in terms of physical properties, safety, storage, and dosage, in order to make the best use and avoid harm.
