After the reaction is completed, 2% 2C3% 2C6-trifluoromethylbenzoic acid can be obtained through cooling, filtration, acidification and other steps. The raw materials for this method are relatively easy to obtain, but the reaction conditions are relatively strict, and the degree of oxidation needs to be precisely controlled, otherwise it is easy to over-oxidize and affect the yield and purity of the product.
Second, take trifluoromethyltoluene as the starting Under the action of light or catalyst, trifluorotoluene reacts with bromine to form bromotrifluorotoluene. Subsequently, bromotrifluorotoluene reacts with magnesium to form Grignard reagent, Grignard reagent reacts with carbon dioxide, and finally is acidified to obtain the target product. This method has a little more steps, but the reaction selectivity of each step is relatively good, which is conducive to improving the purity of the product.
Third, trifluoroacetic anhydride and m-bromotoluene are used as raw materials. The two react in the presence of an appropriate catalyst to form an intermediate product, which is then hydrolyzed and other subsequent reactions to obtain 2% 2C3% 2C6-trifluoromethylbenzoic acid. This synthesis path cleverly uses acylation reaction to effectively construct the target molecular structure, but it requires high reaction conditions and catalysts, and the cost is relatively high.

What are the storage conditions for 2,3,6-trifluorophenylboronic acid?
For 2% 2C3% 2C6-tribromobenzoic acid, the conditions for storage are very important. This medicine should be placed in a cool, dry and well-ventilated place.
If it is cool, the temperature may be too high, or it may cause its chemical change and damage its quality. If it is exposed to the hot sun or high temperature on a hot summer day, it is feared that its molecular structure will move and lose its original effect. Therefore, it is appropriate to choose a cool place, often at room temperature of 20 degrees Celsius, but if it is too high, it is not appropriate.
A dry environment is also important. Tribromobenzoic acid is prone to deliquescence when wet. Moisture enters, or causes it to dissolve and change qualitatively, and the medicinal power gradually fades. And in the humid place, it is easy to produce molds and other substances, which stain its body. When it is protected from water and moisture, a desiccant can be placed in the storage place to absorb its moisture and keep it dry.
Well ventilated, so that the air circulates. If the place is blocked, the gas of medicine must not dissipate, or cause odor to accumulate, and the air is not new, and the temperature and humidity are difficult to adjust. The circulating air can slow down the speed of its deterioration, and also ensure that its environment is clean and free of foul gas.
Furthermore, when it is stored, it should be separated from other objects. Do not store with oxidants, strong alkalis, etc., to prevent chemical reactions and dangerous conditions. And it should be filled in a sealed device to keep air and moisture away, and it has all its properties. In this way, the quality of 2% 2C3% 2C6-tribromobenzoic acid is guaranteed for later use.
