1-Ethoxy-2,3-difluorobenzene is also an organic compound. Its chemical properties such as properties and reactions are quite important, and are related to many fields of chemical industry and scientific research.
This compound has specific physical properties. At room temperature, or in a liquid state, it has a certain volatility and a special odor. Its boiling point and melting point are different due to the presence of fluorine atoms and ethoxy groups in the molecular structure. Fluorine atoms have high electronegativity, causing changes in intermolecular forces, and the melting boiling point is affected.
Chemical properties are active. Oxygen atoms in ethoxy groups have lone pairs of electrons and can participate in nucleophilic substitution reactions. In case of electrophilic reagents, the benzene ring can undergo electrophilic substitution. Due to the positioning effect of fluorine atoms and ethoxy groups, the substitution check point is specific. Fluorine atoms reduce the electron cloud density of the benzene ring, and the reactivity is slightly less than that of benzene, but it can still react with many electrophilic reagents such as halogenating agents and nitrifying agents.
Under basic conditions, ethoxy groups can be replaced by nucleophiles to form new derivatives. In addition, due to the stability of fluorine atoms, the compound can maintain structural stability in some reactions, and can be used as an intermediate to participate in complex organic synthesis, providing the possibility for the construction of special-structured organisms. It has broad prospects in the creation of new drugs, materials and other fields, and is indeed a key substance in organic chemistry research.

The synthesis methods of 1-ethoxy-2,3-difluorobenzene have many different paths, which are described in detail below.
First, it can be prepared by reacting 2,3-difluorophenol with bromoethane under alkaline conditions. In this process, 2,3-difluorophenol is placed in an appropriate amount of organic solvent, such as N, N-dimethylformamide (DMF), and then basic substances such as potassium carbonate are added, and stirred well. Then slowly add bromoethane dropwise, maintain a certain temperature, such as 60-80 ° C, and react for several hours. After the reaction is completed, the target product can be obtained through extraction, washing, drying and distillation. The principle is that phenolic hydroxyl groups form phenoxy anions in an alkaline environment, which enhances nucleophilicity and can undergo nucleophilic substitution reaction with halogenated alkanes to generate corresponding ethers.
Second, 2,3-difluoroaniline is used as the starting material. First, the amino group is converted into diazonium salt, and then reacted with ethanol to obtain 1-ethoxy-2,3-difluorobenzene through hydrolysis and other steps. In specific operation, 2,3-difluoroaniline is dissolved in dilute hydrochloric acid, cooled to 0-5 ° C, and slowly added to sodium nitrite solution for diazotization. After the diazonium salt is prepared, ethanol is added, heated to an appropriate temperature, such as 50-70 ° C, and the reaction is carried out for a period of time. After the reaction is completed, the product is obtained by separation, purification and other operations. This path takes advantage of the activity of diazonium salts to realize the conversion of functional groups and the introduction of ethoxy groups.
Third, through the Grignard reagent method. First, 2,3-difluorophenyl magnesium bromide is prepared, that is, the Grignard reagent is prepared by reacting 2,3-difluorobrobenzene with magnesium chips in anhydrous ether or tetrahydrofuran. Subsequently, it is reacted with chloroethane and the target product can be obtained after subsequent treatment. Anhydrous and anaerobic conditions should be paid attention to during the reaction to ensure the stability of Grignard's reagent and the smooth progress of the reaction. This method is based on the strong nucleophilicity of Grignard's reagent, and nucleophilic substitution occurs with halogenated alkanes to achieve the introduction of ethoxy groups.
The above synthesis methods have their own advantages and disadvantages. In practical application, it is necessary to comprehensively consider factors such as raw material availability, cost and reaction conditions, and choose the appropriate one.

1-Ethoxy-2,3-difluorobenzene is an organic compound. When storing and transporting, many aspects need to be paid attention to.
First, let's talk about storage. First, choose a cool, dry and well-ventilated place. This compound is quite sensitive to heat, and high temperature can easily cause it to deteriorate or cause dangerous reactions. If placed in a humid place, water vapor or interact with some of the active check points, affecting its purity and stability. Second, it should be kept away from fires and heat sources. Because of its flammability, in case of open fire, hot topic or ignition, smoking and hot work are strictly prohibited around. Third, it should be stored separately from oxidants, acids, bases, etc., and must not be mixed. This compound is chemically active, comes into contact with the above substances, or reacts violently, causing serious consequences such as fire and explosion. Fourth, the storage container must be well sealed to prevent it from volatilizing and escaping, polluting the environment, and volatile gases accumulate in the air, or form explosive mixed gases.
As for transportation, first, the transportation vehicle must be equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. To prevent accidents during transportation, it can respond to fires, leaks and other situations in time. Second, summer transportation should be selected in the morning and evening to avoid high temperature. Because high temperature will increase its volatilization and reactivity, resulting in increased risk. Third, during transportation, it should be ensured that the container does not leak, collapse, fall, or damage. When loading and unloading, it should be handled lightly to avoid damage to the container due to brutal operation. Fourth, the exhaust pipe of the vehicle transporting the goods must be equipped with a fire retardant device. To prevent the combustion of compounds caused by exhaust fumes. Fifth, road transportation should be carried according to the specified route, and do not stop in residential areas and densely populated areas. It is forbidden to slip away during railway transportation. In this way, the safety of 1-ethoxy-2,3-difluorobenzene during storage and transportation can be guaranteed to avoid dangerous accidents.
