What are the synthesis methods of 3,5-dichloroiodobenzene?

3,5-Dibromobenzoic acid is a key intermediate in organic synthesis. There are many synthesis methods. Here are the details as follows:
First, benzoic acid is used as the starting material and obtained by bromination reaction. Benzoic acid can be dissolved in an appropriate solvent, such as carbon tetrachloride, and an appropriate amount of catalyst is added, such as iron powder or iron tribromide. Heat up to a suitable temperature and slowly drop bromine. This is because the carboxyl group on the benzene ring is the meta-locator, and the bromine atom will mainly replace the hydrogen atom at the carboxyl group on the benzene ring, thereby generating 3,5-dibromobenzoic acid. The reaction process is roughly as follows: bromine generates an active positive bromine ion under the action of the catalyst, which attacks the benzene ring and undergoes an electrophilic substitution reaction. The advantage of this method is that the raw materials are easy to obtain and the reaction operation is relatively simple; however, the disadvantage is that there are many side reactions, and the separation and purification of the product is slightly complicated.
Second, m-xylene is used as the starting material. First, m-xylene is brominated. Since methyl is an ortho-para-locator, bromine atoms can be selectively introduced into the ortho-para-position of methyl on the benzene ring to generate 3,5-dibromo-m-xylene. Subsequently, methyl is oxidized to a carboxyl group under heating conditions by using a strong oxidant, such as potassium permanganate, to finally obtain 3,5-dibromobenzoic acid. The advantage of this approach is that the bromination reaction has good regioselectivity and can reduce by-products; however, the oxidation step needs to strictly control the reaction conditions, otherwise it may be over-oxidized, and the post-treatment of Third, 3-bromobenzoic acid is used as raw material. Another bromination reaction is carried out. Due to the co-localization effect of carboxyl groups and bromine atoms, the bromination reaction mainly occurs at the common interposition of carboxyl groups and bromine atoms on the 3-bromobenzoic acid benzene ring, and then 3,5-dibromobenzoic acid is generated. This method is relatively short, but the cost of 3-bromobenzoic acid raw materials may be high, which limits its large-scale application to a certain extent.

What are the physical properties of 3,5-dichloroiodobenzene?

3,5-Dinitrobenzoic acid is an organic compound with the following physical properties:
It is a yellow crystalline solid under normal conditions and has stable properties. It is often used as an important raw material or intermediate in many chemical reactions and industrial processes. The melting point of this substance is about 167-170 ° C. This melting point characteristic is crucial in identification and purification. It can be effectively separated and purified by controlling temperature.
3,5-dinitrobenzoic acid is insoluble in water because it is an organic compound. The molecular polarity is very different from that of water. According to the principle of similar miscibility, 3,5-dinitrobenzoic acid with small polarity is insoluble in water with large polarity. However, it is easily soluble in organic solvents such as ethanol and ether. These organic solvents have relatively small polarity and are suitable for the intermolecular force of 3,5-dinitrobenzoic acid, so they can be well miscible. Such solubility characteristics make it possible to choose an appropriate solvent for dissolution, extraction or reaction in related experiments and industrial applications.
3,5-dinitrobenzoic acid has a certain smell, but the smell is not strong and pungent, but as a nitro compound, it has certain toxicity and irritation. Therefore, during operation and use, safety regulations must be strictly followed, and protective measures must be taken to prevent inhalation, ingestion or skin contact, so as to avoid harm to the human body. At the same time, due to its nitro functional group, it also has certain oxidation properties, and can exhibit oxidation characteristics in specific chemical reactions, participating in various oxidation-reduction reactions, which also determines its important position in the field of organic synthesis.

What are the precautions for storing and transporting 3,5-dichloroiodobenzene?

3,5-Dinitrobenzoic acid requires careful attention during storage and transportation. This is a certain dangerous chemical, which is related to the safety of human life and property, and must not be taken lightly.

When storing, the first choice of environment. When placed in a cool, dry and well-ventilated place, away from fire and heat sources. Because it is very sensitive to temperature and humidity, high temperature and humid environment, or its stability is damaged, or even dangerous. The temperature of the warehouse should be controlled within a specific range, and the humidity should also be maintained at an appropriate level.

Furthermore, it should be separated from oxidizing agents, reducing agents, alkalis and other substances. 3,5-Dinitrobenzoic acid is chemically active. Contact with the above substances, or cause severe chemical reactions, resulting in serious consequences such as fire and explosion. At the same time, the storage area should be clearly marked with warning signs, and non-professionals should not enter.

The transportation process should not be sloppy at all. The transportation vehicle must meet the relevant safety standards and have the necessary protection and emergency equipment. When loading and unloading, the operator needs professional protective equipment, handle it with care, and it is strictly forbidden to drop and heavy pressure to prevent chemical leakage caused by package damage.

During transportation, the transportation environment should be closely monitored to ensure stable conditions such as temperature and humidity. If passing through densely populated areas, it is even more prudent to drive, and move according to the specified route and speed to avoid accidents. In the event of an emergency such as a leak, an emergency plan should be activated immediately and effective measures should be taken to prevent the expansion of the hazard. In short, the storage and transportation of 3,5-dinitrobenzoic acid requires a rigorous attitude and professional operation to ensure safety.

What is the market price range for 3,5-dichloroiodobenzene?

3,5-Dihydroxybenzoic acid, the price between markets, often varies depending on the purity of the product and the supply and demand of the market. It is used in all fields, and it is involved in medicine and chemical industry, so its price is difficult to generalize.

In the past, the price of this pure product was slightly higher. If its quality is good, it is more than 90% pure, and the price in the city is one kilogram, or in the spectrum of hundreds of gold. However, if the quality is slightly inferior, mixed in between, the price may drop.

And looking at the supply and demand, when the market demand is high, that is, the quality is not excellent, and the price may rise. And if the supply exceeds the demand, even if the quality is good, the price will not be high. In the past, with the rise of chemical industry, there were many people who wanted this product, and its price rose. After the production capacity gradually increased, the supply was sufficient and the price was flat, and the price also stabilized.

Generally speaking, the price of ordinary 3,5-dihydroxybenzoic acid per kilogram may be between 200 gold and 500 gold. If the quality is good and the special needs are met, the price may be as high as a thousand gold. This special number, the market conditions are ever-changing, and the price is also unstable. If you want to know the exact price, you must also check the market situation carefully and consult the merchants.
