What are the synthesis methods of 2,4,6-trifluorobenzyl alcohol?

The synthesis method of 2% 2C4% 2C6-tribromobenzoic acid has been known for a long time. There are many methods, and the main ones are listed below.

First, based on benzoic acid, obtained by bromination. Take an appropriate amount of benzoic acid first, place it in a reactor, and add an appropriate amount of solvent, such as dichloromethane, to dissolve the benzoic acid. Add a catalyst, such as iron powder or ferric chloride, to promote the reaction. Then add bromine dropwise. When adding dropwise, the temperature should be controlled to a moderate extent to prevent side reactions from being too high. After the bromine is dropped, continue to stir to make the reaction sufficient. After the reaction is completed, separate and purify it by an appropriate method, and obtain 2% 2C4% 2C6-tribromobenzoic acid. < Br >
Second, toluene is used as the starting material. First, toluene is brominated to obtain bromotoluene. When brominated, various isomers of o, m, and p-bromotoluene can be prepared according to different conditions. Then bromotoluene is oxidized to the corresponding bromobenzoic acid. The oxidation method can use strong oxidants such as potassium permanganate and react under appropriate acid-base conditions. After bromobenzoic acid is obtained, bromination is carried out to control the reaction conditions, so that bromine atoms are mainly replaced in the 2, 4, and 6 positions. Finally, after purification, 2% 2C4% 2C6-tribromobenzoic acid can be obtained.

Third, phenol is used as the starting material. Phenol is first reacted with bromine water. Because the phenolic hydroxyl group is a strong activating group, it is easy to make the neighboring and para-hydrogen on the phenyl ring active, and quickly reacts with bromine water to obtain 2% 2C4% 2C6-tribromophenol. Then tribromophenol is carboxylated, and can be converted into 2% 2C4% 2C6-tribromobenzoic acid by reacting with carbon dioxide under appropriate catalyst and pressure and temperature conditions.

Synthesis methods have their own advantages and disadvantages, and should be carefully selected according to actual needs, such as the availability of raw materials, the level of cost, and the purity of the product.

What are the precautions for storing and transporting 2,4,6-trifluorobenzyl alcohol?

2%2C4%2C6-%E4%B8%89%E6%B0%9F%E8%8B%84%E9%86%87, its nature is active, and many matters must be paid attention to when storing and transporting.

First word storage. This substance should be stored in a cool and ventilated warehouse. Because of its volatility, high temperature can easily cause its volatilization to intensify, and even cause safety risks. The temperature of the warehouse should be strictly controlled and should not be too high to prevent its chemical properties from changing. And it needs to be kept away from fire and heat sources. This is the risk of ignition. If it encounters an open flame, it may cause a violent reaction. Furthermore, it should be stored separately from oxidizing agents and acids. Because of its active chemical properties, contact with them or biochemical reactions can lead to danger.

As for transportation, there are also many key points. Before transportation, ensure that the packaging is complete and sealed to prevent leakage. During transportation, the speed of the vehicle should not be too fast, avoid sudden braking, to prevent damage to the packaging. Transportation vehicles should be equipped with corresponding varieties and quantities of fire equipment and leakage emergency treatment equipment. In the event of an accident, they can be responded to in time. And during transportation, they should not stop in densely populated areas or busy areas to prevent leakage from causing harm to the crowd.

In addition, whether it is storage or transportation, those engaged in related operations should be professionally trained and familiar with its characteristics and emergency treatment methods. Daily inspections should also be strengthened to check the storage environment and transportation equipment to ensure safety. In this way, when storing and transporting 2%2C4%2C6-%E4%B8%89%E6%B0%9F%E8%8B%84%E9%86%87, risks can be avoided to the greatest extent and the safety of personnel and the environment can be guaranteed.
