What are the preparation methods of 3-cyano-5-amino-trifluorotoluene?

To prepare 3-amino-5-hydroxy-trifluorotoluene, the following ancient method can be used.

First, fluoroaromatic hydrocarbons are used as starting materials. First, fluoroaromatic hydrocarbons are combined with appropriate nitrogenation reagents, such as the mixed acid of nitric acid and sulfuric acid, and the nitrogenation reaction is carried out at a suitable temperature and conditions to obtain nitro-containing fluoroaromatic hydrocarbons. The key to this step is to control the temperature and the ratio of reagents to prevent overreaction.

Next, the obtained nitro compound is treated with a suitable reducing agent. In the ancient method, either a combination of iron powder and hydrochloric acid, or a sulfide base is used. In a suitable solvent and reaction environment, the nitro group is gradually reduced to an amino group to obtain an amino-containing fluoroaromatic hydrocarbon. When operating, pay attention to the reaction process and product purity.

Then, the hydroxyl group is introduced. It can be achieved by phenylation reaction. Depending on the characteristics of the substrate, a suitable base and reaction conditions are selected. For example, under high temperature and high pressure with a strong base, the halogen atom is replaced by a hydroxyl group. In this process, the choice of solvent, the strength and dosage of the base all have a great influence on the reaction.

Or other methods can be found. First, an aromatic hydrocarbon derivative containing trifluoromethyl is prepared, and then an amino group and a hydroxyl group are introduced in sequence. For example, a suitable substituent is added to the aromatic ring through a specific reaction, which can be converted into amino and hydroxyl groups later. For example, starting with halogenated aromatics, a group containing trifluoromethyl is introduced through the reaction of metal-organic reagents. Then, according to the reduction and substitution methods mentioned earlier, the amino and hydroxyl groups are added in an orderly manner.

During the operation, the conditions of each step of the reaction control and the purification and separation of the intermediate are all important. In this way, 3-amino-5-hydroxy-trifluorotoluene may be obtained.

What should be paid attention to when storing and transporting 3-cyano-5-amino-trifluorotoluene?

3-Amino-5-hydroxy-trifluoromethylpyridine is a precious chemical substance, and many key points must be carefully paid attention to during storage and transportation.

Bear the brunt, and the environment must be dry and cool when storing. This substance is highly susceptible to moisture, and once it is damp, it is very likely to cause its chemical properties to change, affecting quality and efficiency. The warehouse should be selected in a well-ventilated place away from water sources to prevent moisture accumulation.

In addition, temperature is also very important. Excessive temperature may cause it to decompose and deteriorate, so it needs to be stored in a suitable temperature range, usually 2-8 ° C. If conditions are limited, it should not exceed 30 ° C.

The choice of storage containers should not be underestimated. Corrosion-resistant materials should be used, such as glass or specific plastic containers. Because 3-amino-5-hydroxy-trifluoromethyl pyridine may be corrosive to a certain extent, containers made of ordinary materials may be corroded, and then contaminate substances.

As for transportation, the packaging must be stable and tight. Shockproof and collision-resistant materials should be properly wrapped to prevent the container from being damaged and leaking due to bumps and collisions during transportation.

At the same time, the transportation vehicle must also meet specific conditions. The vehicle should be kept dry, ventilated, and not mixed with other substances that are prone to reactions. For example, it should not be transported with strong oxidizing agents, strong acids and alkalis, etc., to prevent dangerous chemical reactions.

The escort personnel must also have professional knowledge and be familiar with the characteristics of 3-amino-5-hydroxy-trifluoromethyl pyridine and emergency treatment methods. In the event of an emergency such as a leak, they can respond quickly and correctly to reduce the harm.
