3-Bromo-2, what is the production method of 6-Difluorobenzotrifluoride
The preparation method of 3-bromo-2,6-difluorotrifluorotoluene is contained in the ancient books, and it is based on the number of cycles.
First, 2,6-difluorotrifluorotoluene is used as the starting material and obtained by bromination reaction. Among them, liquid bromine is often used as the bromine source, supplemented by appropriate catalysts, such as iron powder, iron tribromide, etc. During the reaction, 2,6-difluorotrifluorotoluene is placed in the reaction vessel, an appropriate amount of bromine gas is introduced, and the reaction is stirred at an appropriate temperature. Bromine gas undergoes electrophilic substitution reaction with the benzene ring in 2,6-difluorotoluene. Due to the positioning effect of fluorine atoms on the benzene ring, bromine atoms tend to replace hydrogen atoms in the 3-position, and then generate 3-bromo-2,6-difluorotoluene. After the reaction, the pure product can be obtained by separation and purification, such as distillation, extraction, recrystallization, etc.
Second, starting from 2,6-difluorobenzoic acid. First, 2,6-difluorobenzoic acid is converted into the corresponding acid chloride, and thionyl chloride or phosphorus trichloride are commonly used to react with it. After the acid chloride is obtained, it is fluorinated and treated with fluorinating agents such as hydrofluoric acid and potassium fluoride to convert the carboxyl group into trifluoromethyl. Subsequently, a bromination reaction is carried out. As mentioned above, a bromine source and a catalyst are used to bromide the 3-position of the benzene ring. Finally, 3-bromo-2,6-difluorotrifluorotoluene is obtained through a series of post-treatment steps.
Third, fluorine-containing aromatic compounds are used as raw materials to construct target molecules through multi-step reactions. If a suitable halogenated aromatic hydrocarbon is selected, fluorine atoms are first introduced, and the halogen atoms are replaced by fluoride through a nucleophilic substitution reaction to obtain fluorine-containing aromatic hydrocarbons. Then, trifluoromethyl is introduced, which can be achieved by reacting with trifluoromethylation reagents. Finally, bromine atoms are introduced at specific positions in the benzene ring to complete the synthesis of 3-bromo-2,6-difluorotrifluorotoluene. Although this path has many steps, it can be flexibly adjusted according to the availability of raw materials and the selectivity of the reaction, and is also a common preparation method.
3-Bromo-2, 6-Difluorobenzotrifluoride what to pay attention to when storing and transporting
3-Bromo-2,6-difluorotrifluorotoluene is an organic chemical. When storing and transporting, many key matters need to be paid attention to.
The first thing to pay attention to is its chemical properties. This substance contains halogen atoms such as bromine and fluorine, which are active in nature and have certain chemical activity and corrosiveness. When storing, it should be stored in a cool, dry and well-ventilated place, away from fire and heat sources, to avoid chemical reactions caused by heat or increased volatilization. Because it may react violently with oxidants, strong bases and other substances, it should be stored separately from this type of chemicals, and should not be mixed to prevent danger.
Furthermore, be sure to pack firmly and tightly. In view of its chemical properties, packaging materials need to be able to withstand corrosion, and are often packed in glass, special plastic or metal containers. Glass containers have high transparency and are easy to observe the state of the contents. However, they are fragile. Be careful when using them. Special plastic and metal containers have strong impact resistance and corrosion resistance. The name of the chemical, hazard characteristics, warning signs and other information should be clearly marked on the outside of the package to facilitate identification and safety management.
During transportation, relevant regulations and operating procedures should be strictly followed. Transportation vehicles need to be equipped with corresponding fire protection equipment and leakage emergency treatment equipment, just in case. Transportation personnel should be professionally trained to be familiar with the characteristics of the chemical and emergency treatment methods. When loading and unloading, they must be handled lightly to avoid material leakage caused by damage to the container.
The storage and transportation of 3-bromo-2,6-difluorotrifluorotoluene has a significant impact on the environment and personnel safety. It is necessary to exercise caution to ensure that all links comply with safety regulations and must not be taken lightly to avoid irreparable losses.
