What are the chemical properties of 1-chloro-2,3-dimethylbenzene
1-Chloro-2,3-dimethylbenzene is one of the organic compounds. Its chemical properties are unique and valuable to explore.
The first part of its substitution reaction. Because of its benzene ring, the presence of chlorine atoms and methyl groups changes the electron cloud density distribution of the benzene ring. Methyl is an electron-pushing group, which can increase the electron cloud density of the ortho and para-position relatively. Therefore, during the electrophilic substitution reaction, the substituent groups enter the ortho and para-position of methyl. However, the electronegativity of the chlorine atom is relatively large, which has a certain electron-absorbing induction effect, which affects the reaction activity to some extent. For example, in the bromine reaction catalyzed by iron halide, bromine atomic energy replaces the hydrogen atoms of the methyl ortho and para-position on the benzene ring to form
The second discussion on its oxidation reaction. The methyl group of the side chain can be oxidized under the action of appropriate oxidants. If a strong oxidant such as acidic potassium permanganate solution is used, the methyl group can be gradually oxidized to the carboxyl group. However, this process requires suitable reaction conditions to ensure that the reaction proceeds in the desired direction.
And its reaction with metal reagents. 1-Chloro-2,3-dimethylbenzene can react with metals such as magnesium in anhydrous ether and other solvents to form Grignard reagents. This Grignard reagent is extremely active and can react with a variety of compounds containing carbonyl groups. It is widely used in the field of organic synthesis. It can be used to construct carbon-carbon bonds and expand the complexity of molecular structures.
Furthermore, due to the activity of chlorine atoms, 1-chloro-2,3-dimethylbenzene can undergo nucleophilic substitution reactions. When encountering nucleophilic reagents, such as sodium alcohols, amines, etc., chlorine atoms can be replaced by corresponding nucleophilic groups, thereby preparing a series of new organic compounds. The control of this reaction condition is very critical, such as reaction temperature, solvent properties, etc., which will affect the reaction rate and product selectivity.
1-chloro-2,3-dimethylbenzene has various chemical properties due to its special structure and plays an important role in many fields such as organic synthesis. It is an important object of organic chemistry research.

What are the preparation methods of 1-chloro-2,3-dimethylbenzene?
The preparation methods of 1-chloro-2,3-dimethylbenzene are as follows:
First, 2,3-dimethylaniline is used as the starting material. First, 2,3-dimethylaniline is mixed with hydrochloric acid, cooled to a low temperature, usually at 0-5 ° C, and then slowly added to the sodium nitrite solution to carry out a diazotization reaction to form a diazonium salt. The diazonium salt solution is then mixed with the cuprous chloride hydrochloric acid solution and heated to react. The diazo group is replaced by a chlorine atom to obtain 1-chloro-2,3-dimethylbenzene. This process requires strict control of the reaction temperature and the amount of reagents. If the diazotization reaction temperature is too high, it is easy to cause the decomposition of diazonium salts, which affects the
Second, 2,3-dimethylbenzoic acid is used as a raw material. First, it is reacted with phosphorus pentachloride or thionyl chloride, and the carboxyl group is replaced by a chlorine atom to form 2,3-dimethylbenzoyl chloride. Subsequently, 2,3-dimethylbenzoyl chloride is reduced to 2,3-dimethylbenzyl alcohol under the action of a reducing agent such as lithium aluminum hydride. Next, 2,3-dimethylbenzyl alcohol is reacted with hydrogen chloride gas or chlorine-containing reagents, and the hydroxyl group is replaced by a chlorine atom to finally obtain 1-chloro-2,3-dimethylbenzene. This route has a little more steps, and each step of the reaction needs to ensure that the reaction is complete to improve the yield of the final product.
Third, m-xylene is used as a raw material In the presence of a catalyst, such as iron powder or ferric chloride, m-xylene is substituted with chlorine gas. Since methyl is an ortho-para-locator, the reaction generates a mixture of 1-chloro-2,3-dimethylbenzene and other chlorinated products. Subsequent separation methods such as fractionation and column chromatography are required to obtain pure 1-chloro-2,3-dimethylbenzene. Although the raw materials are easily available, the product separation is relatively complicated, and the reaction conditions need to be precisely controlled to improve the selectivity of the target product.

Due to its volatility and toxicity, once it leaks, it will not only pollute the environment, but also cause harm to the human body. The packaging material needs to be able to withstand the corrosion of the compound to ensure that the packaging is complete during storage and transportation.
Third, the transportation process needs to be cautious. When transporting, it should be driven according to the specified route and do not stop in densely populated areas and residential areas. Because of its potential danger, once an accident occurs, it will cause serious consequences in a densely populated place. Transportation vehicles should be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment, so that they can respond in time in case of emergencies.
Fourth, isolation from other substances cannot be ignored. 1-Chloro-2,3-dimethylbenzene should be stored separately from oxidants, acids, bases, etc., and should not be mixed in storage and transportation. Because it may chemically react with these substances, it may cause danger.
Fifth, the operation and protection should be proper. Storage and transportation personnel need to wear appropriate protective equipment, such as gas masks, protective gloves, etc., to avoid direct contact. After the operation, they should wash and change clothes in time to prevent residual substances from causing harm to the human body.
In short, when storing and transporting 1-chloro-2,3-dimethylbenzene, it is necessary to pay attention to all aspects and operate in strict accordance with regulations to ensure the safety of personnel and the environment from pollution.
