What is 3-Carbomethoxybenzotrifluoride production method?
For 3-methoxycarbonyl trifluorotoluene, the preparation method is as follows:
First, m-trifluoromethylbenzoic acid is used as the beginning, and it is esterified with methanol under the condition of acid catalysis. In this process, the carboxyl group of m-trifluoromethylbenzoic acid and the hydroxyl group of methanol are dehydrated and condensed according to the mechanism of esterification reaction. Commonly used acid catalysts include sulfuric acid and the like. The reaction temperature should be controlled within an appropriate range, usually heated slightly, so that the reaction can proceed smoothly. After the reaction is completed, 3-methoxycarbonyl trifluorotoluene can be obtained by distillation, extraction, drying and other post-treatment methods. The chemical equation of the reaction is as follows: m-trifluoromethylbenzoic acid + methanol $\ underset {heating} {\ overset {acid catalysis} {\ rightleftharpoons}} $3 -methoxycarbonyl trifluorotoluene + water.
Second, m-trifluoromethylbenzoyl chloride and sodium methoxide can be used as raw materials. The acyl chloride group of m-trifluoromethylbenzoyl chloride has high activity, and when it encounters sodium methoxide, a substitution reaction occurs rapidly. The methoxy group of sodium methoxide replaces the chlorine atom of the acyl chloride group to form the target product 3-methoxycarbonyl trifluorotoluene. This reaction is easy to carry out and the conditions are not harsh. After the reaction, it also needs to be separated and purified to obtain a pure product.
Or, with m-trifluoromethylbenzaldehyde as the starting material, the aldehyde group is first oxidized to convert to the carboxyl group to obtain m-trifluoromethylbenzoic acid, and then reacted with methanol according to the above esterification method to obtain 3-methoxycarbonyl trifluorotoluene. During the oxidation process, a suitable oxidizing agent, such as potassium permanganate, can be selected under appropriate solvents and reaction conditions. After obtaining m-trifluoromethylbenzoic acid, esterification can be carried out according to the method described above. All preparation methods have their own advantages and disadvantages, and need to be carefully selected according to actual needs, availability of raw materials and costs.
3-Carbomethoxybenzotrifluoride to pay attention to when storing and transporting

The packaging materials used must be able to resist vibration, collision and friction to prevent damage to the container and material leakage. Transportation vehicles should also be clean, dry, and equipped with corresponding fire and emergency treatment equipment. During driving, drivers must be cautious and avoid violent operations such as sudden braking and sharp turns to avoid packaging damage.
In addition, transportation and storage personnel should be familiar with the characteristics of this compound and emergency treatment methods. In the event of an accident such as a leak, they can respond quickly and appropriately to minimize harm. Therefore, the safety of 3-methoxycarbonyl trifluorotoluene during storage and transportation is guaranteed.
