There are several methods for synthesizing 1 - (chloromethyl) - 2,4 - bis (trifluoromethyl) benzene as follows.
First, 2,4 - bis (trifluoromethyl) benzoic acid is used as the starting material. First, 2,4 - bis (trifluoromethyl) benzoic acid is co-heated with dichlorosulfoxide. In this step, the carboxyl group is converted into an acyl chloride group to obtain 2,4 - bis (trifluoromethyl) benzoyl chloride. Subsequently, the acid chloride is reacted with a reducing agent, such as lithium aluminum hydride, in a suitable solvent, such as anhydrous ether, and the acid chloride group is then reduced to chloromethyl to obtain 1- (chloromethyl) -2,4-bis (trifluoromethyl) benzene. This path step is relatively clear, but lithium aluminum hydride has strong reducing properties, and the operation needs to be cautious, and the reaction conditions are more stringent.
Second, 2,4-bis (trifluoromethyl) toluene is used as the raw material. It allows 2,4-bis (trifluoromethyl) toluene to react with N-chlorosuccinimide (NCS) in a suitable solvent, such as carbon tetrachloride, in the presence of an initiator, such as benzoyl peroxide. This reaction is a radical substitution reaction. NCS provides chlorine radicals to attack the methyl group of toluene and substitutes to produce 1- (chloromethyl) -2,4-bis (trifluoromethyl) benzene. The raw materials for this method are relatively easy to obtain, and the reaction conditions are relatively mild. However, side reactions may occur during the reaction process, and the reaction conditions need to be carefully adjusted to improve the selectivity of the product.
Third, 2,4-bis (trifluoromethyl) bromobenzene is used as the starting material. First, 2,4-bis (trifluoromethyl) bromobenzene is reacted with magnesium chips in anhydrous ether to make Grignard's reagent 2,4-bis (trifluoromethyl) phenylmagnesium bromide. Then the Grignard's reagent is reacted with formaldehyde to generate the corresponding alcohol. Finally, the alcohol hydroxyl group is converted into chloromethyl by chlorination reagent, such as thionyl chloride, and the target product 1- (chloromethyl) -2,4-bis (trifluoromethyl) benzene can also be obtained. This synthesis route has a little more steps, but each step is more classic and easy to control. As long as the operation process is strictly followed, a higher yield can be obtained.

1 - (chloromethyl) - 2,4 - bis (trifluoromethyl) benzene is a chemical substance, and care must be taken when storing and transporting it.
When storing, the first environment. It should be placed in a cool, dry and well-ventilated place, away from fires and heat sources. This is because it has certain chemical activity, high temperature or open flame is easily dangerous. And it needs to be placed separately from oxidizing agents, strong bases and other substances to prevent chemical reactions. Because of its active nature, contact with other substances or react violently, endangering safety.
Furthermore, storage containers are also crucial. A well-sealed container must be used to prevent it from evaporating and escaping. Due to its volatile gas or toxicity and irritation, it endangers the human body and the environment. And the material of the container should be compatible with the chemical, and it should not react with it to ensure stable storage.
As for transportation, there are also many details. Transportation vehicles must meet safety standards and be equipped with corresponding fire and emergency equipment. During transportation, it is necessary to ensure that the container is stable and will not collide or tip over. Due to collision or damage to the container, the chemical leaks, causing serious consequences.
The escort personnel also need professional training and are familiar with the nature of this substance and emergency treatment methods. In the event of an accident such as a leak, they can respond quickly and correctly to reduce hazards. And the transportation route planning should also be careful to avoid densely populated areas and environmentally sensitive areas to reduce risks. In this way, the safe storage and transportation of 1- (chloromethyl) -2,4-bis (trifluoromethyl) benzene can be guaranteed.

1 - (chloromethyl) - 2,4 - bis (trifluoromethyl) benzene, the impact of this substance on the environment should not be underestimated. Looking at its chemical structure, the groups containing chloromethyl and ditrifluoromethyl have unique properties or have various effects on environmental factors.
Bearing the brunt, it is volatile to the atmospheric environment, escapes into the atmosphere, or participates in photochemical reactions. Under specific conditions, chlorine atoms and fluorine atoms can trigger a series of chain reactions, interfere with the balance of free radicals in the atmosphere, and then affect the oxidation capacity of the atmosphere. And it may pose a potential threat to the ozone layer. Although it is weaker than traditional chlorofluorocarbons, it cannot be ignored for long-term accumulation.
As for the aquatic environment, if this substance enters the water body, it is easily adsorbed on the surface of suspended particles due to its hydrophobicity and chemical stability, or insoluble in water. It migrates with the water flow, or settles into the bottom sediments, and persists in the aquatic ecosystem for a long time. Its toxicity or toxic effect on aquatic organisms, interferes with the physiological metabolism, reproduction and other processes of aquatic organisms, and affects biodiversity.
In the soil environment, it adsorbs on the surface of soil particles, affecting the physical and chemical properties of the soil. And due to the slow degradation of microorganisms, or the continuous accumulation in the soil, it changes the structure and function of the soil microbial community, and affects the material cycle and energy conversion of the soil ecosystem.
Because of its stable chemical properties, it is difficult to degrade in the environment, or is transmitted and bioenriched through the food chain. After ingestion of low-trophic level organisms, the concentration in high-trophic level organisms may increase significantly, threatening organisms and even human health.
In summary, 1- (chloromethyl) -2,4-bis (trifluoromethyl) benzene has potential effects in various environmental media, which is related to ecological balance and biological security. It is urgent to study in depth to understand its mechanism of action, find appropriate strategies to deal with it, and protect the ecological environment.
