What are the main uses of 4-bromofluorobenzene?

4- Of the, its use is not the same. "Tiangong" says: "Each of the, has its own master." It probably has three main uses.

First, it is used to facilitate the stomach, and it comes out of the. Mortal people do not eat, or the cold is out of place, causing the of the stomach to be born. Stop, the abdomen, abdominal pain, stool and other diseases. This use of, can, so that the can be solved, and the can be solved. Such as a big, its nature is fierce, there is, can be introduced to the new,, The evil of fire can cause pain in the eyes and mouth on the top; it can cause dry stool and red urine on the bottom. The evil of fire can be made to come out from the bottom, so "It is better to stop the boiling than to draw from the bottom". Such as mirabilite, the taste is cold, it can not only be burned down, but also clear the fire. It is especially suitable for those who are in the stomach.

Third, it can be washed away by water. If the evil of water overflows, stop gathering in the water, water, abdominal and other diseases. There is the power of chasing water in the middle, which can make the evil of water come out, so that the two can come out to eliminate the disease. Such as gansui and Euphorbia, its nature is fierce, good at attacking and chasing water, and can treat severe diseases such as pleural fluid and ascites. However, this medicine is often toxic, and it should be used with caution, while the disease is stopped, it should not be used, so as not to be correct.

It is used in Tongfu, fire poison, and water evil, but its nature is more severe and fierce. It must be clear about the cause of the disease. It is appropriate to use it reasonably, so as to obtain its benefits and avoid its harm.

What are the physical properties of 4-bromofluorobenzene?

4- Migratory shark, with various physical characteristics. Its body is streamlined, which can reduce the resistance of the water and make its speed faster when swimming in the water. The skin covers the small shield scales, which are both firm and slippery, not only can protect its body, but also help it reduce flow resistance and improve efficiency when swimming.

Its muscles are strong, especially the lateral muscles, which are the source of swimming force. They can be used for strong contraction and relaxation, so that it can swim quickly, turn, and be flexible in the water. The fins are also crucial. The dorsal fin stabilizes its posture and does not turn over; the pectoral fin and abdominal fin control its lifting and turning; the caudal fin is the main force for propulsion. When swinging, it pushes the water and then allows the shark to move forward.

Furthermore, the 4-migratory shark has keen senses. Although its eyes are slightly limited in deep-sea vision, they are quite sensitive to changes in light and shadow, which helps it identify objects and hunt in different waters of light and shade. The inner ear is balanced, and it can also keep the body stable in complex water flows. The most amazing thing is its lateral line and Lorentz ampulla. The lateral line can sense subtle changes in water flow and know the movement of surrounding organisms; Lorentz ampulla can detect the biological electric field, that is, hidden under the sediment, and it is difficult to escape its detection, so as to accurately hunt and survive and reproduce.

Its gill structure is exquisite, and the surface area of gill filaments is wide, which can efficiently absorb oxygen in the water to meet the body's oxygen needs when swimming at high speed. And the body temperature of the 4-migratory shark is slightly higher than the water temperature, which is different from the temperature of normal fish, making its muscles more responsive and metabolic. It can live in different cold and warm waters, and perform long-distance migrations, shuttling through the seas, and living endlessly.

What are the chemical properties of 4-bromofluorobenzene?

The crystals of sulfuric acid containing water, the general formula is\ (MgSO_ {4}\ cdot nH_ {2} O\), and the common one is sulfuric acid heptahydrate\ (MgSO_ {4}\ cdot 7H_ {2} O\).

Its shape is mostly transparent crystals or orthorhombic crystals, which are brittle in the ground. In terms of solubility, it is easy to dissolve in water and form a clear solution. This solution is neutral because its degree of hydrolysis of sulfate in water is very small.

The reverse reaction of the reaction, the soluble reaction, such as chlorination\ (BaCl_ {2}\), the rapid reaction of the sulfate, the formation of sulfuric acid\ (BaSO_ {4}\) white sediment, the equation of transformation\ (MgSO_ {4} + BaCl_ {2} = BaSO_ {4}\ downarrow + MgCl_ {2}\).

In case of oxidation, such as oxidizing\ (NaOH\),

What are the synthesis methods of 4-bromofluorobenzene?

4 - There are many ways to make Mianchi lotus root in ancient times, and I will describe them in detail.

One is the method of candied lotus root. Take the fresh and tender Mianchi lotus root, wash it, peel it, and cut it into thin slices. Soak it in water for a few hours to remove its astringent taste. Then remove it and drain the water. Put water in the pot, add an appropriate amount of honey, and boil it slowly over low heat. When the honey water is slightly thicker, put in the lotus root slices, and stir gently, so that each lotus root is covered with honey liquid. Continue to boil for a while, until the lotus root slices are bright, remove it, and place it in a ventilated place to dry. This candied lotus root is sweet but not greasy. The lotus root aroma blends with honey fragrance, and the flavor is unique.

The second is the method of cold salad. Choose the crispy and tender lotus root, cut it into filaments, and rinse it with water to remove the starch. Boil a pot of boiling water, blanch the lotus root filaments in the water for a while, quickly fish them out, and put them in cold water, so that the lotus root filaments can be kept crispy. Take a basin, put in the lotus root filaments, add minced garlic, minced ginger, refined salt, vinegar, sesame oil, and a little white sugar, and mix well. This cold lotus root silk is hot and sour and appetizing. It is eaten in summer, which is refreshing and pleasant.

The third is the method of stewing. Choose the old and cooked lotus root in Mianchi and cut it into pieces. Add water to the pot, add an appropriate amount of lotus root, red dates, and rock sugar. After boiling over high heat, turn to low heat and simmer slowly. Simmer until the lotus root is soft and waxy, the soup is thick, and the lotus root fragrance is overflowing. This

The fourth method is to fry the lotus root box. Cut the lotus root into a blade, and put the seasoned meat filling in the middle. Take flour, starch, add water to make a batter, and add a little baking powder to make the fried product crispier. The lotus root box is wrapped in batter, fry it in a pan of hot oil until golden and remove it. This fried lotus root box is crispy on the outside and tender on the inside, and the meat aroma complements the lotus root aroma. It is a delicacy on the table.

What are the precautions for the storage and transportation of 4-bromofluorobenzene?

4-In the middle of the storage environment, it is necessary to pay attention to the general situation, so as to ensure the safety and security of its products.

The storage area is essential. It is best to keep it in a dry, transparent and safe place, and avoid fire sources and high-temperature environments. Green is flammable, and it is easy to ignite or even explode in case of open fire, high-temperature. If it is exposed to moisture, it is easy to be invaded by water, resulting in deterioration of the product. In addition, the storage container also needs to be careful, and it has good tightness to prevent mixing and consumption.

The first package is properly packed. Use the container or packaging material to pack tightly to ensure that it does not leak in the process. It is also necessary to comply with the relative safety standards, and to prepare the necessary fire-fighting equipment for leakage and emergency management. It is necessary to ensure the safety of the environment and other environmental factors, such as heavy rain and high temperature, etc.

In addition, in case of poor weather or poor weather, it is necessary to follow the relative method. Establish and improve the management system, such as the amount of inventory, route, access and other information, in order to facilitate retrospective management. In this way, it is necessary to ensure the safety of the environment in the process of storage, and the quality of the product is constant.
