What are the preparation methods of 2-chloro-4,5-difluorobenzoic acid?

2-% -4,5-divinylbenzoic acid is a common compound, and there are many methods for synthesis. The following methods are generally used:

First, the starting material is benzaldehyde derivatives. First, take the benzaldehyde with a specific substituent and make it vinyl Grignard or vinyl. This reaction needs to be carried out in a low-temperature and low-water environment, such as tetrafuran solution, under nitrogen protection. Grignard or attack the carbonyl group of benzaldehyde to generate a medium alcohol. And, using the oxidation of, such as active dioxide or Dice-butyl oxide, alcohol oxidation phase of ketone. Then, through the reaction reaction, an atom is introduced, which is replaced by a cyanyl group and hydrolyzed to obtain the carboxyl moiety of the molecule, and 2-% -4,5-divinylbenzoic acid is prepared.

Second, a derivative of benzene is used. As a starting material for benzene, a vinyl substituent is introduced through the alkylation reaction. This reaction is often used as a catalyst for water trichloride, and under the addition of benzene, the vinyl benzene reaction is made. To obtain a divinylbenzene derivative, which is oxidized and reversed by the reaction reaction, and can be vinylated to a carboxyl group. The oxidizing agent can be oxidized with high acid or heavy acid, etc., and the reaction agent can be used in either acidic or acidic components. However, the reaction agent needs to be controlled to avoid the oxidation of benzene. Only 2-% -4,5-divinylbenzoic acid can be prepared.

Third, the reaction agent can be prepared by the reaction agent. Molecules containing alkenyl and carboxyl groups can be used to make their biochemical molecules. For example, by reversing the free radicals of alkenyl, benzene can be built first, and the functionality of vinyl and carboxyl groups can be retained at specific positions of benzene. The reaction agent can use the oxide to introduce free radicals, and it can be processed under the appropriate solution and degree of solution. However, through functional reversal, such as protection and oxidation, 2-% -4,5-divinylbenzoic acid is obtained.

What is the price range of 2-chloro-4,5-difluorobenzoic acid in the market?

I don't know what you mean by "2 -% E6% B0% AF - 4% 2C5 - %E4%BA%8C%E6%B0%9F%E8%8B%AF%E7%94%B2%E9%85%B8". Looking at this logo, it seems to be a special code for electronic data, which I can't directly understand. If you want to know the price range of this thing in the market, you need to know what it is exactly, and the market environment it is in is complex and changeable. Supply and demand relations, quality differences, geographical differences, and seasonal fluctuations can all affect the price.

Such as ordinary goods, the price is low in a good year, and the price is high in a bad year; those with good quality are expensive, and those with poor quality are cheap; in prosperous cities, due to strong demand and high operating costs, their price may be higher than that in remote places. However, I don't know what kind of "2 -% E6% B0% AF - 4% 2C5 - %E4%BA%8C%E6%B0%9F%E8%8B%AF%E7%94%B2%E9%85%B8" is, and it is difficult to determine its price range. If you can specify the characteristics, purpose, quality and other details of this object, I may be more helpful to you and estimate its approximate price range.

What are the storage conditions for 2-chloro-4,5-difluorobenzoic acid?

2-% -4,5-dienylacetic acid should be stored in a dry place to avoid high temperatures in open flames. This compound has certain chemical properties, and in case of fire or open flame, it is afraid of danger. Therefore, where it is stored, the degree of oxidation should not be high, and it needs to be well passed to ensure safety.

It is also suitable to oxidize. The connection of oxidation, or the reaction of strong oxidation, will cause trouble. Where it is stored, the two must be separated and not allowed to be separated.

The container stored is also investigated. It must be well sealed to prevent leakage. The leakage of this compound does not cause waves, and it may contaminate the environment and endanger the people and things around it. The container with solid materials can prevent the container from breaking and causing leakage.

Furthermore, it is necessary to store all suitable and urgent equipment. Such as fire appliances, it is not needed. In the event of an accident, it can be used immediately to control the situation and reduce damage. And there are clear warnings as appropriate, so that people know that the hidden items are dangerous and act with extra caution. In this way, the proper storage of 2-%-4,5-dienylacetic acid should not be ignored.
