1% 2C2% 2C3% 2C4-tetrabromonaphthalene, that is, 1,2,3,4-tetrabromonaphthalene, this physical property is complex, and I will describe it separately.
Looking at its physical properties, 1,2,3,4-tetrabromonaphthalene is a solid at room temperature, and its melting and boiling point depends on factors such as intermolecular forces. Generally speaking, the melting and boiling point of solid substances is relatively high, which is due to the close bonding between molecules. To change its state requires more energy.
In terms of solubility, 1,2,3,4-tetrabromonaphthalene is difficult to dissolve in water. Water is a polar molecule, while 1,2,3,4-tetrabromonaphthalene molecules have weaker polarities. According to the principle of "similar miscibility", the polarities are different, so it is difficult to dissolve. However, it is soluble in some organic solvents, such as benzene, chloroform, etc., because these organic solvents have similarities with the intermolecular forces of 1,2,3,4-tetrabromonaphthalene, and can be miscible with each other.
When it comes to chemical properties, bromine atoms in 1,2,3,4-tetrabromonaphthalene are more active. Bromine atoms have electron-absorbing properties, which reduce the electron cloud density of the naphthalene ring, thereby affecting their reactivity. Under certain conditions, substitution reactions can occur, such as nucleophilic substitution reactions, and halogen atoms can be replaced by other nucleophilic reagents. At the same time, they can also participate in some redox reactions, and bromine atoms are variable in valence, resulting in oxidation or reduction changes in the whole molecule.
In addition, 1,2,3,4-tetrabromonaphthalene contains multiple bromine atoms, which will produce bromine-containing toxic gases during combustion, which is harmful to the environment and the human body. And because of its stable chemical structure, it is difficult to degrade in the environment, easy to accumulate, and has a great potential threat to the ecological environment.
In summary, 1,2,3,4-tetrabromonaphthalene has its own characteristics of melting point and solubility in physical properties. Chemically, bromine atoms are active, which can cause it to have a variety of reactions. And because it contains bromine, it is harmful to the environment. Be careful when using and disposing.

1% 2C2% 2C3% 2C4-tetrahydronaphthalene, its chemical properties are still stable. This compound has a two-ring structure, one is a benzene ring and the other is a hydrogenated naphthalene ring. The benzene ring, because of its conjugation system, has high stability and is not easy to be broken by ordinary chemical reagents. Although the hydrogenated naphthalene ring is more active, it is not very reactive.
Under normal temperature and pressure, tetrahydronaphthalene can withstand most common chemical environments. In the air, if there is no high temperature, open flame or strong oxidant, it rarely reacts spontaneously. With its stability to water and general neutral, weakly acidic and weakly basic solutions, it is not easy to react with hydrolysis and addition.
When encountering strong oxidants, such as acidic solutions of potassium dichromate, or high temperature, high pressure and the presence of a catalyst, tetrahydronaphthalene will also change. Strong oxidants can cause ring rupture and oxidation reactions; high temperature, high pressure and catalysts can promote hydrogenation, dehydrogenation, isomerization and other reactions. However, such conditions are not normal environments. Overall, under normal chemical operation and storage conditions, the chemical properties of 1% 2C2% 2C3% 2C4-tetrahydronaphthalene are quite stable.

First take the essence of gold, silver, copper, and iron, and refine it with a secret method to make it pure and impure. Then find the thousand-year-old cold stone, break it into powder, and mix it with the essence. Also take the water of the spiritual spring, reconcile it, and make it blend as one.
Put this mixture in a special cauldron furnace, and calcine it with samadhi true fire. The heat must be precisely controlled. At the beginning, the fire should be gentle, so that all things slowly blend; then the fire will become more and more fierce, urging its transformation; finally the fire will turn gentle and determine its shape.
When calcining, special guards are required, and there must be no slack. Watch its color change, smell the difference in its breath, and wait for its color to be warm and moist, and its breath to be calm.
After it is released from the oven, carve it with a magic axe while it is hot, and shape it into the desired shape according to its material characteristics. When carving, the technique should be delicate and the lines should be smooth, so that it can fully reveal its charm.
Afterwards, nourish it with spiritual liquid, so that it absorbs the spiritual energy of heaven and earth and contains its own spiritual charm. After these several processes, you can get 1%2C2%2C3%2C4-%E5%9B%9B%E6%B0%9F%E8%8B%AF%E7%9A%84%E5%88%B6%E5%A4%87%E7%B1%BB%E7%89%A9%E4%BD%93.
However, this process, the materials are rare, the processes are complicated, and it is difficult to succeed without great perseverance, great wisdom, and great opportunity. And every step is about success or failure. If there is a slight mistake, all previous achievements will be lost. Therefore, if you want to make this thing, you need to be cautious and make thorough preparations.

When it is hidden, it must choose a high and dry place to cover it to avoid the trouble of water and wetness. This place must be solid and ventilated, so that the medicinal gas will not dissipate and can last for a long time. If it is in a humid place, the medicinal materials are easy to rot and rot, and it is unusable.
When handling, be careful. Handle with care and do not make collisions. 1%2C2%2C3%2C4-%E5%9B%9B%E6%B0%9F%E8%8B%AF%E6%9C%AC%E8%B4%A8%E8%BD%BB%E8%80%8C%E8%89%B2%E6%98%8E, it is easy to break if you are not careful. After breaking, not only the appearance is damaged, but the medicinal power may also be reduced.
The utensils transported should be clean and dry. If the utensils are unclean, or other things are mixed in them, the medicinal materials are easily contaminated. And during transportation, it is protected from the sun and rain. The ingredients in the medicine may evaporate and dissipate, and the rain will cause it to deteriorate with moisture.
Furthermore, when storing, it should be classified and placed. Do not put it with peculiar smells to prevent odors. 1%2C2%2C3%2C4-%E5%9B%9B%E6%B0%9F%E8%8B%AF%E6%9C%89%E5%85%B6%E7%89%B9%E6%9C%89%E4%B9%8B%E5%91%B3, if it is mixed with other smells, it will lose its original taste and affect the efficacy of the medicine.
Caretakers should do their best. Always inspect the storage place to see if there is any abnormality. If the humidity is high or low, if the humidity is too high, take measures to dehumidify it as soon as possible; observe the rise and fall of temperature, and try to cool down if it overheats, so that the storage environment is suitable for the long-term storage of medicinal materials. In this way, 1%2C2%2C3%2C4-%E5%9B%9B%E6%B0%9F%E8%8B%AF%E5%9C%A8%E5%82%A8%E5%AD%98%E5%92%8C%E8%BF%90%E8%BE%93%E8%BF%87%E7%A8%8B%E4%B8%AD%E4%B8%8D%E5%A4%B1%E5%8E%9F%E6%80%A7 can be kept for other uses.
