What are the synthesis methods of 4-Amino-3, 5-Dibromobenzotrifluoride
The synthesis method of 4-amino-3,5-dibromotrifluorotoluene has been recorded in many past books and is described in detail below.
First, trifluorotoluene is used as the starting material, and bromine atoms are introduced through a bromination reaction. Usually liquid bromine is used as a brominating agent, and under the action of appropriate catalysts such as iron powder or iron tribromide, at a specific temperature and reaction environment, bromine atoms selectively replace hydrogen atoms at specific positions on the benzene ring to generate 3,5-dibromotrifluorotoluene. This process requires fine regulation of the reaction temperature and the ratio of raw materials to prevent side reactions such as excessive bromination.
Then, 3,5-dibromotrifluorotoluene is nitrified. 4-Nitro-3,5-dibromotrifluorotoluene is obtained by introducing nitro groups into the benzene ring using mixed acid (a mixture of nitric acid and sulfuric acid) as a nitrifying reagent. The key to this step is to control the concentration of mixed acid, reaction temperature and time to ensure that nitro groups are accurately introduced into the target location and avoid excessive impurities.
Finally, 4-nitro-3,5-dibromotrifluorotoluene is reduced to 4-amino-3,5-dibromotrifluorotoluene. Common reduction methods are catalytic hydrogenation, using palladium carbon as a catalyst to reduce in a hydrogen atmosphere; chemical reduction methods can also be used, such as iron powder, zinc powder and other metals and acids, to reduce nitro groups to amino groups.
Another synthetic approach is to use an amino-containing benzene derivative as the starting material, first protect the amino group, and then through a series of reactions such as bromination and trifluoromethylation, the target product can also be obtained. The purpose of protecting the amino group is to prevent it from being affected in subsequent reactions. After the introduction of other groups, the protective group is removed.
Synthesis of 4-amino-3,5-dibromotrifluorotoluene requires rigorous operation and attention to the control of reaction conditions in order to improve the yield and purity.
4-Amino-3, what are the precautions in storage and transportation of 5-Dibromobenzotrifluoride
For 4-amino-3,5-dibromotrifluorotoluene, many matters must be paid attention to during storage and transportation.
This compound has special properties and is stored in a dry environment. If the environment is humid, water vapor is easy to interact with the compound, or cause it to react such as hydrolysis, which will damage its purity and quality. Therefore, it should be placed in a dry and ventilated place, and it should be stored in a sealed container to prevent moisture from invading.
Temperature is also critical. Excessive temperature may cause it to decompose and evaporate, and too low temperature may affect its physical state, causing inconvenience during use. Generally speaking, it should be stored in a cool place, and the temperature should be maintained at 2-8 ° C. This temperature range can ensure its chemical properties are relatively stable.
Light should not be underestimated. The compound may be sensitive to light, under light, or cause luminescent chemical reactions to cause it to deteriorate. Therefore, the storage place should be protected from direct light, and it is appropriate to hold it in a dark container or place it in a dark place.
As for transportation, it is necessary to follow relevant laws and standards because it may be dangerous. The transportation container must be strong and well sealed to prevent leakage. During loading and unloading, the operator should handle it with care, and do not vibrate or hit violently to avoid damage to the container. During transportation, it is also necessary to control the temperature and avoid light to ensure that the transportation environment is similar to the storage requirements, so that the quality of 4-amino-3,5-dibromotrifluorotoluene can be guaranteed during storage and transportation, and it can arrive at the destination safely.
