2-%28Bromomethyl%29-1%2C3%2C4-Trifluorobenzene, the Chinese name is 2 - (bromomethyl) - 1,3,4 - trifluorobenzene. This physical property is very special, let me explain.
Its outer color is usually yellow to light color liquid, and it has flow properties, such as clear spring water. Smell it, or have a special smell, but this taste is not pungent, and it also has the smell of ordinary things. Smell it, you can feel the special taste of its chemical substances.
Its melting temperature, melting temperature is low, and it is often low in the liquid, and the boiling temperature depends on its chemical characteristics, usually at a certain degree. This boiling is affected by the molecular force. Because the molecules contain bromine, fluorine and other atoms, the molecular force has its own characteristics, so the boiling force also has a specific value.
In terms of solubility, 2- (bromomethyl) -1,3,4-trifluorobenzene has good solubility in soluble materials, such as ether and toluene. However, in water, its solubility is very poor. Because of the hydrophobicity of the molecules and the harmony of water molecules, it is mostly oil floating on the water surface in water.
In addition, its density is also special, and the phase density is higher than that of water. When it drops into water, it can sink in the bottom of the water, such as stone. This density characteristic also refers to the amount of bromine and fluorine atoms in the molecule and the density of the phase.
Its chemical activity is low. Due to the existence of bromomethyl in the molecule, it is easy to generate nuclear substitution inverse. This inverse property makes it valuable in the synthetic field, and can be used as an important synthetic material for the identification of various compounds. And the introduction of fluorine atoms gives it special chemical and physical properties, so that the materials synthesized from this raw material may have special biological activity, resistance and other characteristics, and have a promising future in many fields such as engineering and materials.

2-%28Bromomethyl%29-1%2C3%2C4-Trifluorobenzene is 2- (bromomethyl) -1,3,4-trifluorobenzene, and its synthesis method is as follows:
First, 1,3,4-trifluorobenzene is used as the starting material. First, through the Fu-gram alkylation reaction, under the catalysis of Lewis acid such as anhydrous aluminum trichloride, react with chloromethyl methyl ether, and stir at a suitable temperature such as 0-5 ° C for a certain period of time to generate 2- (chloromethyl) -1,3,4-trifluorobenzene. This step of the reaction needs to be carried out in an anhydrous and anaerobic environment to ensure the smooth reaction. Subsequently, 2 - (chloromethyl) - 1,3,4 - trifluorobenzene and sodium bromide are heated and refluxed in acetone solution, and the target product 2 - (bromomethyl) - 1,3,4 - trifluorobenzene can be obtained through halogen exchange reaction. During this process, attention should be paid to controlling the reaction temperature and time to ensure a higher yield.
Second, 1,3,4 - trifluorobenzoic acid is used as the starting material. First, it is esterified with methanol catalyzed by concentrated sulfuric acid, and heated and refluxed for several hours to obtain 1,3,4 - methyl trifluorobenzoate. Next, lithium aluminum hydride is used to reduce it, and tetrahydrofuran solution of lithium aluminum hydride is slowly added at low temperature such as 0 ° C. After the reaction, it is hydrolyzed to obtain 1,3,4-trifluorobenzyl alcohol. Then react 1,3,4-trifluorobenzyl alcohol with phosphorus tribromide at low temperature to obtain 2- (bromomethyl) -1,3,4-trifluorobenzene. There are many steps in this route, but the reaction conditions of each step are relatively mild. Pay attention to the removal of impurities and separation operations after each step of the reaction to improve the purity of the product.
When synthesizing 2- (bromomethyl) -1,3,4-trifluorobenzene, it is necessary to carefully select the appropriate synthesis route according to the actual needs and conditions, and strictly control the reaction conditions to achieve the ideal synthesis effect.

2 - (bromomethyl) - 1,3,4 - trifluorobenzene is an organic compound, which has certain special properties. When storing and transporting, many aspects must be paid attention to.
First words storage. Because of its chemical activity, it needs to be placed in a cool, dry and well-ventilated place. This is to prevent it from reacting with water vapor, oxygen and other components in the air. If the environment is humid, water vapor or reactions such as hydrolysis of compounds will damage its purity and quality; poor ventilation, volatile gases or accumulation of compounds will cause safety hazards.
Furthermore, it should be kept away from fire and heat sources. 2 - (bromomethyl) - 1,3,4 - trifluorobenzene or flammable, in case of open flame, hot topic or cause combustion or even explosion, so the storage place is strictly prohibited fireworks, electrical equipment must also have explosion-proof function.
At the same time, it should be stored separately from oxidants and strong bases, and must not be mixed. Due to its chemical structure characteristics, contact with oxidants or severe oxidation reactions; encounters with strong bases, or reactions such as alkali hydrolysis, can cause dangerous conditions, such as fire, explosion, or the formation of harmful products.
Storage containers are also crucial, and suitable materials should be selected. Corrosion-resistant glass bottles or specific plastic bottles should be used to ensure that the containers are well sealed to prevent leakage. Because the compound may be toxic and corrosive, once it leaks, it not only pollutes the environment, but also threatens human health.
As for transportation, relevant regulations and standards must be strictly adhered to. Transportation vehicles must have corresponding safety signs and protective facilities, such as fire extinguishers, leakage emergency treatment equipment, etc. During transportation, it should be protected from exposure to the sun and rain to avoid the impact of high temperature and humid environment on the compound. When loading and unloading, operators should be careful to prevent leakage caused by damage to the container. If a leak occurs during transportation, emergency measures should be taken immediately to evacuate the crowd, seal the site, and properly handle it according to the characteristics of the compound.

2-%28Bromomethyl%29-1%2C3%2C4-Trifluorobenzene is 2- (bromomethyl) -1,3,4-trifluorobenzene, the impact of this substance on the environment should not be underestimated.
It has certain toxicity. If released in the environment, or diffused by water, soil, and air. In the aquatic environment, it may cause poisoning to aquatic organisms and interfere with their normal physiological functions, such as hindering fish respiration, affecting reproduction, and long-term population decline. In the soil, or absorbed by plant roots, it affects plant growth and development, and even passes through the food chain, endangering organisms that feed on plants.
In addition, its chemical properties are active, in the atmosphere or participate in photochemical reactions, affect air quality, generate harmful secondary pollutants, such as ozone, etc., damage human health and affect atmospheric visibility. And because it is difficult to degrade, it can exist in the environment for a long time, accumulate continuously, and cause more lasting and extensive harm.
When manufacturing, using and handling products containing 2- (bromomethyl) -1,3,4-trifluorobenzene, proper protective measures should be taken to avoid its leakage to the environment. Once leaked, effective cleaning measures should be taken quickly to reduce the harm to the environment.
