What are the physical properties of p-Methylbenzotrifluoride?
P - Methylbenzotrifluoride is an organic compound with unique physical properties. It is a colorless liquid, clear and transparent in appearance, and has a special smell.
When it comes to the melting point, it is about -52 ° C. It is a solid state at this low temperature and has a stable structure. The boiling point is between 175 and 177 ° C. When heated to this temperature, it changes from liquid to gaseous state. Its density is about 1.18 g/cm ³, which is heavier than water and will settle in water.
In terms of solubility, it is difficult to dissolve in water because its molecular structure contains hydrophobic trifluoromethyl and methyl, and the force between it and water molecules is weak. However, it can be soluble in many organic solvents, such as ethanol, ether, acetone, etc., and can form a similar miscibility effect with these organic solvent molecules.
In addition, the compound has a certain volatility. At room temperature and pressure, the molecules are easy to escape from the liquid surface into the air. When using, pay attention to ventilation to avoid its vapor accumulation. And its chemical properties are relatively stable at room temperature, but under certain conditions, such as high temperature, light or the presence of catalysts, substitution, addition and other reactions can occur.
What is the chemistry of p-Methylbenzotrifluoride?
P-Methylbenzotrifluoride, Chinese name, methyltrifluorotoluene, is a kind of benzene compound. It has special properties and is used in the field of synthetic benzene.
This substance is a color solution and has an aromatic taste. The boiling temperature is not high, and it is easy to burn under normal conditions. The density is small in water, the water is insoluble, and it floats on the water.
In terms of chemical activity, the methyl and trifluoromethyl groups on the benzene have a huge impact on the density of the benzene sub-cloud, resulting in the modification of benzene. Trifluoromethyl has a strong absorber effect, which reduces the density of the benzene sub-cloud, so that the benzene substitutes for the anti-benzene to be produced. The methyl group is the supplier of the benzene sub-group, which can neutralize part of the absorber to a certain extent, but still makes the benzene anti-benzene activity lower than that of benzene.
In addition, the new substituent mainly enters the methyl position and the trifluoromethyl position due to the localization effect of the trifluoromethyl group. For example, nitrification and inversion, mainly generating methyl and trifluoromethyl positions substituted by nitro groups.
In addition, its energy is often high, such as gold, generating new compounds, which can be used in the synthesis of compounds, compounds and functional materials. Its special chemical properties can be used as an important medium in the synthesis of fluorine-containing compounds, providing special properties of products, such as biological activity, corrosion resistance, etc.
What is p-Methylbenzotrifluoride production method?
The method of preparing p-methyl trifluorotoluene often begins with p-methyl benzyl chloride, so that it reacts with anhydrous hydrogen fluoride under suitable reaction conditions for nucleophilic substitution. First, prepare p-methyl benzyl chloride and anhydrous hydrogen fluoride to control the reaction temperature, pressure and time. The reaction temperature is mostly in a moderate range, so as to promote the reaction and avoid side reactions. Pressure is also exquisite, and it must be adjusted to an appropriate value to facilitate the contact and reaction of the reactants. Time control is also critical. If the time is short, the reaction will not be complete, and the time will consume resources and may produce by-products.
In the reaction, the fluorine atom of anhydrous hydrogen fluoride attacks the benzyl carbon of methyl chlorobenzyl, and the chlorine atom leaves to form a pair of methyl trifluorotoluene. In this process, a catalyst is often required to increase the reaction rate and yield. The catalyst may be a specific metal salt or an organic compound, which helps the reactant activity increase and the reaction activation energy decrease.
After the reaction is completed, the product is mixed with unreacted raw materials, catalysts, etc. It must be separated and purified before the pure product can be obtained. By distillation, p-methyltrifluorotoluene can be fractionated according to the boiling point difference of each component. Extraction, adsorption, etc. can also be used to remove impurities and purify to obtain high-purity p-methyltrifluorotoluene to meet the needs of industry and scientific research.
p-Methylbenzotrifluoride what are the precautions during use
P-methyltrifluorotoluene is also a commonly used raw material in the chemical industry. During its use, all precautions should not be ignored.
Bear the brunt, safety is the most important. This material is toxic and irritating to a certain extent, and can cause discomfort when it touches the skin, eyes, or inhales its vapor. Therefore, when operating, protective equipment is essential, such as gas masks, protective gloves, protective glasses, etc., to keep it safe.
In addition, the method of storage is also critical. It needs to be placed in a cool and well-ventilated place, away from fire and heat sources, to prevent fire. And it should be stored separately from oxidants, alkalis, etc., and must not be mixed to avoid chemical reactions and accidents.
In addition, the ventilation of the use environment must be ensured to be good. In a confined space, its vapor is easy to accumulate, reaching a certain concentration, and will cause combustion and explosion in case of open flame or high heat energy. Therefore, ventilation equipment must operate normally to disperse harmful gases in time.
During the operation process, the standard steps should not be missed. Accurate measurement, follow the established process, and must not be changed without authorization. In the event of a leak, do not panic, quickly evacuate personnel to a safe area, cut off the fire source, and collect and clean up the leak in the correct way to prevent pollution of the environment.
In short, the use of p-methyltrifluorotoluene should be based on safety and handled carefully to avoid disasters and ensure smooth production.
