4-% oxygenated acid (1:1), which is often used for manufacturing, and is of great importance.
One of them is to be used in manufacturing, and the use is essential. In the manufacturing process, it can be boiled and boiled to help the lignin dissolve, so that the product can be divided, and the finished product is good. Moreover, it can be used for printing and dyeing, and it can be used for refining. In addition to cotton, it can be naturally used to clear the cloth surface and increase the dyeing effect.
Second, in the chemical processing room, it is also commonly used. For performance, it can be used to reduce the acidity of the solution, and it can be used to control the reaction environment. It can also neutralize and reverse, and determine the acidity of the acid, which is very important for analysis.
Third, it is also useful in the field of daily life. In the cleaning process, important raw materials can decompose oil pollution due to their quality, such as heavy oil pollution in the house. Thanks to this, it can effectively remove oil and keep the environment clean.
Fourth, it is also indispensable in water management. It can correct the pH value of water, remove heavy gold particles in the water, make it sink, improve water quality, and keep water safe.
Therefore, 4-% oxygenated acid (1:1) plays an important role in many aspects such as work, room, life and water management. It has a wide range of uses, and it can meet the needs of people's livelihood.

To prepare 4-% aminophenyl boronic acid (1:1), the method is as follows:
First take an appropriate amount of 4-bromoaniline, place it in a reactor, and dissolve it with an appropriate amount of organic solvent, such as tetrahydrofuran, so that the 4-bromoaniline is completely dissolved to form a uniform solution.
Then, in a low temperature environment, slowly add n-butyl lithium. In addition, you need to be careful and pay close attention to the temperature changes of the reaction system to prevent the reaction from getting out of control due to the sudden rise in temperature. The reaction of n-butyl lithium with 4-bromoaniline to form a lithiated intermediate is very important, and the purity of the product is determined by the precise position of the lithiated product.
After the lithification reaction is completed, the reaction system is maintained at a low temperature, and then trimethyl borate Trimethyl borate reacts with the lithiated intermediate, and through a series of transformations, the prototype of 4-% aminophenylboronic acid (1:1) is formed.
After the reaction is completed, the reaction mixture is treated with an appropriate amount of dilute acid solution, such as dilute hydrochloric acid, to precipitate the product from the reaction system. After that, the impurities are removed by means of extraction and washing. During the extraction, a suitable organic solvent, such as ethyl acetate, can be used to extract multiple times to improve the yield of the product. During the washing process, the organic phase is washed with water and saturated salt water in sequence to further remove impurities.
Finally, the obtained organic phase is dried, and a desiccant such as anhydrous sodium sulfate can be used. After drying is complete, the organic solvent is removed by distillation under reduced pressure to obtain a crude product. Then the crude product is purified by recrystallization and other methods, and a suitable solvent is selected, such as ethanol-water mixed solvent, heated to dissolve the crude product, and then slowly cooled to allow the product to crystallize and precipitate. After filtration and drying, a pure 4-% aminophenyl boronic acid (1:1) is obtained.

4-% oxygenated acid (1:1), if it is hidden in the warehouse, it will be hard for those who pay attention.
First seal. Both of these are water-absorbing, exposed to air, and easy to deliquescence. The deliquescence should not only cause its temperature to be reduced, but also affect the container, so it must be filled in a sealed vessel, and the air should be connected.
Times and isolation. 4-% oxygenated acid (1:1) activity should not be combined with acid, gold powder, etc. In the case of acid, it will cause strong neutralization and reaction, or life-threatening; gold powder may also be reversed, resulting in improved quality.
In addition, the degree of resistance is also important. It is appropriate to avoid high tides when it is dry and dry. High tides can promote its reaction rate to increase faster, and the danger of deliquescence is even worse.
The damage of containers should not be ignored. Use corrosion-resistant materials, such as glass, plastic, etc. Containers made of gold containers are easy to use, and it is like a lead.
On the way, the stencil must be placed firmly to prevent collision and collapse. If the product leaks, it is not only a wave, but also a human and stained environment. Once it leaks, it should be cleaned up according to the method of cleaning, such as washing with a lot of water, and then neutralizing it with the appropriate product.
Therefore, the storage of 4-% oxygenated acid (1:1) should be done in accordance with the general conditions and pay attention to the general conditions in order to ensure its safety and use.

In today's world, the price of 4-hydroxypyridinecarboxylic acid (1:1) in the market often changes for many reasons. Its price often fluctuates within a certain range, reaching the price per kilogram, ranging from hundreds of yuan at low prices to thousands of yuan at high prices.
The reason for this is the situation of supply and demand. If at some point, the industry's demand for 4-hydroxypyridinecarboxylic acid (1:1) increases sharply, but the supply is limited, and the demand exceeds the supply, the price will rise. On the contrary, if the supply exceeds the demand, the merchant wants to sell its goods quickly, and the price will tend to drop.
Furthermore, the price of raw materials also has a great impact. The preparation of 4-hydroxypyridinecarboxylic acid (1:1), the raw material of Wright's decision. If the price of raw materials fluctuates, the quality of the product will also change. If the price of raw materials rises, the cost of making 4-hydroxypyridinecarboxylic acid (1:1) will increase. In order to protect their profits, merchants must raise their prices.
And the technology and regulations of production also affect the price. The emergence of new technologies may increase the yield and reduce the cost, and the price may drop accordingly. However, if the regulations change, such as the stricter environmental protection regulations, the factory needs to invest more in environmental protection measures, and the cost will increase and the price will also increase.
And the competition in the market also has an effect on the price. When there is competition in the same industry, merchants may lower their prices to attract customers. If there is little competition in the market, merchants have the right to set prices, and prices may be higher.
In summary, the market price of 4-hydroxypyridinecarboxylic acid (1:1) often fluctuates between hundreds of yuan per kilogram and thousands of yuan per kilogram, which is due to the interaction of supply and demand, raw material prices, production technology and competition.
