1-Fluoro-3- (trifluoromethyl) benzene is also an organic compound. Its unique physical properties are the key to understanding this substance.
First of all, its phase state and appearance, under room temperature and pressure, often appear colorless and transparent liquid, clear and free of impurities. It can be seen that its fluidity is quite good, like smart water, but it has different characteristics.
Second, its smell usually emits a weak and special aromatic smell. This smell is not as rich and sweet as the floral aroma, nor is it pungent and foul. However, it is unique and one of its characteristics.
Furthermore, its boiling point is fixed, about 103 ° C to 105 ° C. When the temperature rises, the substance gradually changes from the liquid state to the gaseous state, the binding between molecules weakens, and begins to dissipate freely. The melting point is about -63 ° C, and the molecular movement slows down, the arrangement becomes more orderly, and the substance solidifies from the liquid state to the solid state.
Its density is slightly lighter than that of water, about 1.32g/cm ³. When placed in water, it can be seen that it floats on the water surface, and the two are clearly defined and do not mix.
In terms of solubility, 1-fluoro-3- (trifluoromethyl) benzene is difficult to dissolve in water, because water is a polar molecule, and the polarity of the substance is weak. According to the principle of "similar miscibility", the two are difficult to miscible. However, it is soluble in many organic solvents, such as ethanol, ether, etc. In such solvents, it can be uniformly dispersed to form a uniform solution.
In addition, the vapor pressure of this substance is also an important physical property. The vapor pressure increases with the increase of temperature, which is due to the intensification of the thermal movement of molecules. More molecules escape from the liquid surface and enter the gas phase, resulting in an increase in vapor pressure. This property is of great significance to the consideration of its volatilization degree and safety during chemical production, storage and use.

1-Fluoro-3- (trifluoromethyl) benzene, its chemical properties are quite stable. This compound contains fluorine atoms, and the electronegativity of fluorine is extremely high, resulting in strong C-F bond energy. The fluorine atoms and trifluoromethyl groups on the aromatic ring have a great impact on the chemical stability of the substance.
From the structural point of view, the aromatic ring has a conjugated system, and the electron cloud is distributed off-domain, which makes its structure stable. Trifluoromethyl is a strong electron-absorbing group, which can disperse the electron cloud of the benzene ring and enhance the stability of the system. At the same time, the C-F bond is not easy to break due to the characteristics of fluorine atoms.
In chemical reactions, 1-fluoro-3- (trifluoromethyl) benzene usually exhibits relative inertness. In nucleophilic substitution reactions, the difficulty of attacking nucleophiles increases due to the decrease in electron cloud density of the benzene ring due to trifluoromethyl. In electrophilic substitution reactions, although benzene rings can undergo such reactions, the electron-absorbing effect of trifluoromethyl makes the reaction activity lower than that of benzene, and the reaction check point is selective, which is affected by the effect of substituent localization.
In terms of thermal stability, due to the action of C-F bond and aromatic ring conjugation system, the compound can withstand higher temperatures and is not easily decomposed. However, under certain conditions, such as strong oxidizing agent, high temperature and high pressure and the presence of catalyst, its chemical stability may be broken and corresponding chemical reactions occur. But overall, under conventional conditions, the chemical properties of 1-fluoro-3- (trifluoromethyl) benzene are relatively stable.

The preparation method of 1-fluoro-3- (trifluoromethyl) benzene is described in many books in the past, and is listed as follows:
First, the halogenation method. Using m-trifluoromethylaniline as the starting material, in a low temperature and strong acid environment, it reacts with sodium nitrite for diazotization to form diazonium salts. Subsequently, fluoroborate ions are introduced to obtain diazoic salts of fluoroborate, which are decomposed by heating, escape nitrogen gas, and finally obtain 1-fluoro-3- (trifluoromethyl) benzene. This diazotization reaction requires careful control of temperature, and the reagents used are toxic. Double attention should be paid to the operation.
Second, nucleophilic substitution method. Using m-trifluoromethylchlorobenzene or m-trifluoromethylbromobenzene as the substrate, select a suitable fluorine source, such as potassium fluoride, etc. In an aprotic solvent, a phase transfer catalyst is added to raise the temperature to promote the replacement of halogen atoms by fluorine atoms to obtain the target product. The raw materials used in this method are easy to purchase, but the reaction conditions are harsh and the equipment requirements are quite high.
Third, arylation method. With the help of transition metal catalysis, fluorine-containing aryl halides are arylated with trifluoromethylating reagents. Commonly used transition metals include palladium, copper, etc., which need to be matched with specific ligands. This approach has good selectivity and yield, but the high cost of catalysts limits its large-scale application.
Fourth, electrochemical synthesis method. Using the compound containing the corresponding group as raw material, in a specific electrolyte, through electrochemical oxidation or reduction process, the carbon-fluorine bond is constructed to generate 1-fluoro-3- (trifluoromethyl) benzene. The method is green and environmentally friendly, but the technology is still in the development stage and the industrial application needs to be improved.

1-Fluoro-3- (trifluoromethyl) benzene is also an organic compound. When storing and transporting it, many matters must be paid attention to.
Let's talk about storage first. This material is flammable, so it should be placed in a cool and ventilated warehouse. The temperature of the warehouse should not be too high to prevent it from being dangerous due to heat. And it must be kept away from fires and heat sources. Open flames and hot topics are taboo. Because of its sensitivity to air and moisture, the container must be sealed to prevent the intrusion of air and moisture and prevent it from deteriorating. At the same time, it should be placed separately from oxidants and food chemicals, and must not be mixed to prevent chemical reactions from occurring and causing disasters.
Let's talk about transportation. At the time of transportation, the vehicle must be equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. Summer transportation should be selected in the morning and evening to avoid exposure to the hot sun, because high temperature will increase its danger. During transportation, make sure that the container does not leak, collapse, fall or damage. Transportation vehicles should follow the prescribed route and do not stop in residential areas and densely populated areas, so as to avoid accidents and endanger many lives. When loading and unloading, light loading and unloading are strictly prohibited. Dropping, heavy pressure and friction are strictly prohibited to prevent damage to the container and cause material leakage.
All of these are important for the storage and transportation of 1-fluoro-3- (trifluoromethyl) benzene. Practitioners should keep in mind and proceed with caution to ensure safety.
