What are the production methods of 2,4-dichloro -α,α,α- trifluorotoluene

The preparation method of 2% 2C4-dioxy - α，α，α - trifluorotoluene has been known for a long time. In the past, the alchemists wanted a wonder drug, and they studied the changes in physical properties between the Dan furnace and the tripod. Although they did not directly refer to this substance, their accumulated experience was also the foundation for later preparation methods.

One method can start from halogenated aromatics. First, aromatics are used as the basis, and halogenated atoms are attached to aromatic rings. This halogenation method, or halogen elements, are combined with aromatics under the help of light or catalysts. Then, when introducing an oxygen-containing group, a strong oxidizing agent such as permanganate can be used to convert the carbon and hydrogen of the side chain of the aromatic ring into an oxygen-containing structure, and gradually build a dioxy structure. As for the introduction of trifluoromethyl, fluorine-containing reagents are often used. In the past, there were reagents such as potassium fluoride, and suitable halogenates. Under specific solvents and conditions, nucleophilic substitution was performed, and fluorine atoms were substituted one by one to obtain trifluoromethyl.

There is another way to start with oxygen-containing heterocyclic compounds. Choose a suitable heterocyclic ring, and its structure may already have the embryonic form of partial dioxy. Through reactions such as ring opening and rearrangement, the molecular structure is adjusted. In the following steps, the method of introducing trifluoromethyl as described above is carefully handled to make each atom in its safe position to form 2% 2C4-dioxy - α，α，α - trifluorotoluene.

In the process of preparation, it is necessary to pay attention to the physical properties and study the reaction conditions in detail. Temperature, pressure, and solvent properties are all related to the success or failure of the reaction. If the temperature is too high, it may cause a lot of side reactions; if the pressure is not appropriate, the reaction will be biased in other ways. The choice of solvent should be in harmony with the reactants and products, which not only helps the reaction to proceed, but also facilitates separation and purification. Therefore, in order to obtain this compound, it is necessary to study carefully in all links to achieve the desired result.

If you accidentally touch the skin, rinse quickly with a lot of water, and still feel unwell, you need to seek medical attention; if it enters the eye, rinse immediately with a lot of water and seek medical treatment.

Furthermore, storage should also be cautious. It should be stored in a cool and well-ventilated place, away from fire and heat sources. Because of its flammability, the temperature of the warehouse should not be too high, and it should be stored separately from oxidants, edible chemicals, etc., and should not be mixed. At the same time, the warehouse should be equipped with suitable materials to contain leaks.

During use, ventilation conditions are essential. It must be operated in a well-ventilated environment, preferably in a fume hood to reduce its concentration in the air and reduce inhalation hazards. And care should be taken during operation to avoid its leakage. In the event of a leak, personnel from the leaked contaminated area should be quickly evacuated to a safe area and isolated to strictly restrict access. Emergency responders must wear self-contained positive pressure breathing apparatus and anti-toxic clothing. Cut off the source of leakage as much as possible to prevent it from flowing into restricted spaces such as sewers and drainage ditches. In the event of a small amount of leakage, it can be mixed with sand, dry lime or soda ash and collected in a dry, clean and covered container. In the event of a large amount of leakage, build a dike or dig a pit for containment, cover it with foam to reduce steam disasters, and then transfer it to a tanker or a special collector for recycling or transportation to a waste treatment site for disposal.

In addition, its disposal is also exquisite. Relevant laws and regulations and environmental protection requirements should be followed, and it should not be discarded at will. Generally speaking, it should be handled by a qualified professional treatment agency according to specific processes and processes to avoid pollution to the environment.
