What is the preparation method of 2-Cyano-5-nitrobenzotrifluoride?

2-Cyano-5-nitrotrifluorotoluene is an important compound in the field of organic synthesis. Its preparation method often follows the following paths.

First, benzene derivatives containing corresponding substituents are used as starting materials. For example, starting from 2-methyl-5-nitrotrifluorotoluene, through a mild oxidation step, the commonly used oxidizing agents such as potassium permanganate or potassium dichromate, under suitable reaction conditions, such as in a specific solvent (such as basic solvents such as pyridine), and a suitable temperature range (usually controlled at 50-80 ° C), oxidize the methyl group to a carboxyl group to obtain 2-carboxyl-5-nitrotrifluorotoluene. Then, this carboxyl compound can be reacted with ammonia under heating and in the presence of a catalyst, such as a highly active metal oxide as a catalyst, at 150-200 ° C to convert the carboxyl group into an amide group. 2-Cyano-5-nitrotrifluorotoluene is obtained by dehydrating at high temperature (200-300 ℃) through the action of dehydrating agents such as phosphorus pentoxide.

Second, halogenated aromatics are used as starting materials. First, 2-halogen-5-nitrotrifluorotoluene is reacted with cyanizing reagents such as potassium cyanide or sodium cyanide in the presence of phase transfer catalysts (such as quaternary ammonium salts) in polar organic solvents (such as N, N-dimethylformamide), and the temperature is controlled at 80-120 ℃. The halogen atom is replaced by a cyano group to prepare the target product. The key to this path lies in the activity of the halogen atom and the reactivity of the cyanide reagent. The choice of phase transfer catalyst is also extremely important, which can promote the smooth reaction between the two phases.

Third, nitroaromatic hydrocarbons are used as the starting materials. First, 2-nitro-5-trifluoromethylbenzoic acid is converted into the corresponding ester through esterification reaction, and suitable alcohol and acid catalysts (such as sulfuric acid, etc.) are selected to react under heating and reflux conditions. Then, the ester reacts with ammonia in an alcohol solution to form an amide, and then dehydrates with a dehydrating agent to form a cyanide group to complete the preparation of 2-cyano-5-nitrotrifluorotoluene. In this process, the conditions of each step of the reaction need to be precisely controlled. The temperature and time of the esterification reaction, the dosage of reagents and the reaction temperature of the amidation and dehydration reactions have a significant impact on the yield and purity of the product.

2-Cyano-5-nitrobenzotrifluoride What are the precautions in storage and transportation?

2-Cyano-5-nitrotrifluorotoluene is an organic chemical substance. When storing and transporting, pay attention to many matters.

First words storage. This material is dangerous and should be stored in a cool, dry and well-ventilated place. Avoid direct sunlight, which may cause chemical reactions due to light or damage its quality, or even cause danger. The temperature of the warehouse should be controlled within a specific range to prevent it from being unstable due to excessive temperature. And it should be stored in isolation from oxidizing agents, reducing agents, acids, alkalis, etc., because they may react violently with them, causing the risk of fire and explosion. The storage place must be prepared with suitable materials to contain leaks to prevent rapid response in case of accidents.

Times and transportation. Before transportation, it is necessary to ensure that the packaging is complete and sealed. Packaging materials must have anti-corrosion, pressure resistance and other characteristics, which can resist vibration and collision during transportation. During transportation, the driving should be stable, avoid sudden braking and sharp turns, and avoid packaging damage. Transportation vehicles must have obvious dangerous goods labels, and be equipped with corresponding fire equipment and emergency treatment equipment. Transportation personnel should be professionally trained and familiar with the dangerous characteristics of the substance and emergency disposal methods. If there is a leak during transportation, corresponding measures should be taken immediately to evacuate the crowd, seal the scene, and be properly handled by professional personnel.

In short, the storage and transportation of 2-cyano-5-nitrotrifluorotoluene is related to safety, and all details should not be ignored. It must be operated in strict accordance with regulations to ensure safety.
