1-Methyl-4- (trifluoromethoxy) benzene, its physical properties are described as follows.
Looking at its appearance, it is often a colorless and transparent liquid, which can be seen in sunlight. It has a specific aromatic smell. This smell is not strong and pungent, but it is also clearly recognizable.
When it comes to boiling point, it is between 138-140 ° C. At this temperature, the substance gradually changes from liquid to gaseous state. This is because the molecule is energized and the movement intensifies enough to break free from the liquid phase. The melting point is about -43 ° C. When the temperature drops below this point, the substance solidifies from liquid to solid, and the molecular arrangement tends to be ordered from disorder.
Its density is about 1.22 g/cm ³, which is heavier than water. If it is placed in one place with water, it will sink underwater. In terms of solubility, it is slightly soluble in water, and its molecular structure contains hydrophobic methyl groups and trifluoromethoxy groups, and the force between water molecules is weak. However, it is soluble in many organic solvents, such as ethanol, ether, acetone, etc. Due to the principle of "similar phase dissolution", it can interact with organic solvent molecules and can be mixed with each other.
In addition, the vapor pressure of 1-methyl-4- (trifluoromethoxy) benzene has a certain value at room temperature, indicating that its molecules tend to escape from the liquid phase to the gas phase. This property also affects its diffusion and evaporation rate in air. Its refractive index also has a specific value, and when light passes through the substance, the direction of propagation will change accordingly according to its specific refractive index. These are all important physical properties of 1-methyl-4- (trifluoromethoxy) benzene.

1-Methyl-4- (trifluoromethoxy) benzene, this is an organic compound. Its chemical properties are of great interest and are closely related to many organic reactions and practical applications.
Looking at its structure, above the benzene ring, the methyl group is in the opposite position to the trifluoromethoxy group. Trifluoromethoxy, due to the extremely high electronegativity of fluorine atoms, gives this compound unique electronic properties. This highly electronegative fluorine atom makes the trifluoromethoxy group exhibit a strong electron-absorbing effect, which greatly affects the electron cloud density distribution of the benzene ring and reduces the electron cloud density of the benzene ring.
In the electrophilic substitution reaction, due to the strong electron-absorbing effect of trifluoromethoxy, the activity of this compound is lower than that of benzene. When the electrophilic reagent attacks, it is more inclined to the meso-site. The electron cloud density of the adjacent and para-sites decreases more significantly due to the electron-absorbing effect, while the meso-site retains part of the electron cloud density, which is easier to accept the attack of electrophilic reagents.
Furthermore, the methyl group in this compound can participate in the reaction. Affected by the benzene ring and the trifluoromethoxy group, the α-hydrogen atom activity of the methyl group changes. In case of appropriate reagents, reactions such as oxidation can occur, and the methyl group can be converted into functional groups such as carboxyl groups.
The physical properties of this compound are also affected by the structure. Due to the existence of the trifluoromethoxy group, its molecular polarity increases, resulting in differences in physical parameters such as boiling point and melting point from ben
In organic solvents, its solubility varies depending on the polarity of the solvent. In polar solvents, the solubility may be better than that of non-polar solvents due to intermolecular forces.
The chemical properties of 1-methyl-4- (trifluoromethoxy) benzene are determined by its unique structure. The interaction of electron-absorbing trifluoromethoxy group with benzene ring and methyl group shows potential application value in organic synthesis and materials science.

1-Methyl-4- (trifluoromethoxy) benzene. To make this substance, there are several common methods.
First, p-methylphenol is used as the starting material. It is first combined with a base, such as sodium hydroxide, to form sodium phenol. The activity of sodium phenol increases, making it easier to react with trifluoromethylating reagents, such as trifluoromethylsulfonyl fluoride (CF 🥰 SO 🥰 F), under suitable conditions, such as in organic solvents, such as N, N - dimethylformamide (DMF), temperature control reaction. In this reaction, the oxygen anion of sodium phenol nucleophilically attacks the sulfur atom of the trifluoromethylation reagent, and then 1-methyl-4- (trifluoromethoxy) benzene is obtained.
Second, p-methyl halobenzene is used as the starting material. If it is p-methylchlorobenzene, it is first interacted with metal magnesium to make Grignard's reagent. Grignard's reagent has strong nucleophilic properties and can be used with trifluoromethyl ether compounds, such as trifluoromethoxy trimethylsilane (CF < OSi (CH <) <), in anhydrous ether or tetrahydrofuran solvents, through nucleophilic substitution reaction, the target product can also be obtained. It is necessary to pay attention to the reaction environment to be anhydrous
Third, a coupling reaction catalyzed by palladium. In the presence of palladium catalysts, such as tetra (triphenylphosphine) palladium (Pd (PPh)), and bases, the reaction conditions are mild and the selectivity is good, and 1-methyl-4- (trifluoromethoxy) benzene can be efficiently synthesized. During the reaction, the palladium catalyst is first coordinated with aryl boric acid and halogenated hydrocarbons, and through the steps of oxidative addition, metallization, reduction and elimination, the target product is formed.

1-Methyl-4- (trifluoromethoxy) benzene is an organic compound. During storage and transportation, many matters need to be paid careful attention.
This compound is volatile. When storing, the first thing is to choose a cool and ventilated warehouse. Because the temperature is too high, its volatilization will increase, one will cause material loss, and the other will cause the accumulation of volatile gases, or the risk of explosion. The temperature of the warehouse should be controlled within a specific range, such as not exceeding 30 ° C. And it must be kept away from fire and heat sources. Open flames and hot topics can cause its volatilization to accelerate and even cause combustion.
Furthermore, the substance should be stored separately from oxidants, acids, alkalis, etc., and must not be mixed. Due to its active chemical properties, contact with the above substances is prone to chemical reactions, or serious accidents such as fire and explosion.
The storage place should also be equipped with suitable materials to contain leaks. In case of leakage, it can be properly handled in time to avoid its spread and cause greater harm to the environment and personal safety.
When transporting, the transportation vehicle must be equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. During driving, the driver must drive carefully to prevent the vehicle from bumping and colliding, causing package damage and material leakage. During transportation, ensure that the container does not leak, collapse, fall or damage. And transport according to the specified route, do not stop in densely populated areas and residential areas. When loading and unloading, operators should also pay attention to light loading and light unloading, and strictly prohibit bumping and impact to ensure safe transportation.
