Benzene 1 Bromo 3 Fluoro 5 Iodo

This compound is called "Dan Sand". Dan Sand is a spiritual object created by heaven and earth, and is described in the "Tiangong Kaiwu". Its color is as red as a pill, its quality is heavy and unique, and it has been valued by the Fang family of warlocks since ancient times, and it is also used by doctors.
According to the "Tiangong Kaiwu", Dan Sand originated in the deep mountains of Chen and Jinzhu prefectures. Its mountains are piled on top of each other, the clouds are shrouded in mist, and the spiritual energy gathers, so you can conceive this treasure. The method of mining Dan Sand is quite difficult. Miners need to enter deep mines, walk forward by candle, and search for traces of Dan Sand in dark and humid places.
The nature of Dan Sand is quiet, but it changes when it encounters fire. After calcining and refining, it can be turned into mercury, which is the magic of Dan Sand. Mercury is as agile as water, but it is as dignified as gold. It has wonderful uses in many fields such as alchemy and medicine.
Ancient alchemists regarded Dan Sha as the foundation of a wonderful medicine for longevity. With Dan Sha as the main material, supplemented by other things, it has been refined under complicated conditions, and it is expected to be an elixir that prolongs life. Although looking at it today, his pursuit of longevity is mostly false, but at that time, the magic of Dan Sha is deeply rooted in the hearts of the people.
Doctors also attach great importance to Dan Sha. It has the effect of calming and calming the nerves, and can treat palpitations and insomnia. Because Dan Sha is subject to the qi of heaven and earth to yin, it can calm the mind and make the mind peaceful.
Dan Sha has a special position in the Chinese civilization. It is not only a precious mineral, but also carries the ancients' exploration of the mysteries of heaven and earth and the pursuit of eternal life, shining with unique brilliance in the long river of history.

This compound has a variety of physical properties. In terms of its color state, it may be solid at room temperature, and its appearance may be crystalline. The texture may be more delicate, like finely crushed ice crystals, radiant and shiny; or it may be liquid, flowing like smart water, which may be clear and transparent, without impurities.
On the smell, it may emit a fresh and elegant fragrance, such as the stamen that blooms in spring, which is fragrant and pleasant; it may also have a pungent and unpleasant smell, which is like a rancid smell, which makes people cover their noses.
The solubility is very important. In water, it may be very easy to dissolve, just like salt fused into water, which is instantly shadowless and forms a uniform and stable solution; it may also be difficult to dissolve in water, such as oil floating on the water surface, which is distinct from water. In organic solvents, the solubility is different, and it may be miscible with some organic solvents, and the phase is seamless.
Melting point and boiling point have their own characteristics. The melting point is high, and it needs high temperature to turn it from solid to liquid, just like a tough metal, which needs to be smelted by fire; or low, it will melt into a liquid after a little heat near room temperature. The same is true for boiling points. For high boiling points, strong heat is required to make it boil and vaporize; for low boiling points, it will melt into a gaseous state after a little heating.
Density is also an important property. Compared with water, or greater than water, it will sink to the bottom of the water when thrown into the water, like a stone entering the water; or less than water, it will float on the water surface.
These physical properties are interrelated and together outline the unique physical appearance of this compound, which is a key consideration when identifying, isolating, and applying this compound.

This compound is mild in nature, pure in color but firm in quality, stable in nature but difficult to melt. Its nature melts in case of fire, but it is not flammable. It melts at high temperature, melts but does not burn, only flows into a liquid state, cools and hardens, and the quality remains unchanged. When it encounters water, it is safe, does not hydrate with water, does not react, sinks underwater, like a stone falling into an abyss pool, does not disturb water waves. It is in acid, and it responds slowly, when the acid is weak, it should be late, when the acid is strong, it should be fast, and it should produce gas in time, such as micro-bubbles in a spring, gradually dispersing in the air. As for alkali, there is also a reaction, depending on the strength, concentration and dilute of the alkali, or slow or slow, the product should be different, mostly new salts, or containing metal ions combined with alkali roots.
This substance also has electrical conductivity, but it is weaker than a good conductor, between the conductor and the insulator. If it is passed through with current, it can be seen that the micro-electricity should be used as a material for weak electrical conduction. And it has a certain magnetic conductivity. In a magnetic field, it can sense magnetic force and respond slightly. Although it is not as significant as ferromagnetic objects, it cannot be ignored. Its thermal conductivity is also moderate, neither fast heat transfer material, nor very good heat insulation, so when the temperature changes, it needs a certain amount of time to heat up and cool down, and can be used for temperature control and slow change. Although its chemical properties are not very active, under appropriate conditions, it can react with many substances to form other substances, which are determined by its internal molecular structure and atomic arrangement. Therefore, in various chemical situations, it shows various characteristics, which is used in the chemical industry, materials and other industries, and has great achievements.

To make this compound, there are many methods, each with its own advantages and disadvantages, and the method is selected as needed.
One is the combination of ancient methods. Collect all related things and mix them with the method in a certain order. Take a few things first, put them in a clean vessel, then slow down the heat, wait for it to melt a little, then add the B product, stir it slowly, so that the two are even. During the process, pay attention to the change of the heat, do not overheat to cause decomposition of the substance, nor overcooling and incomplete synthesis. The key to this method is to precisely control the temperature and stir to make the reaction uniform, but it takes a long time and requires a high degree of heat control.
The second is the method of extraction. Find the natural material containing this compound and extract it with a suitable solvent. When selecting a solvent, it is necessary to consider its solubility to the compound and the difficulty of separating it from other components of the material. The material is crushed, immersed in a solvent, and stirred from time to time to promote the dissolution of the compound. Then, by filtration, distillation and other methods, the solvent and impurities are removed to obtain a pure product. The advantage of this method lies in the use of natural substances, which are more green and environmentally friendly. However, the content of the compound in natural materials may be low, and the extraction efficiency is sometimes poor.
The third is a modern synthesis method. With advanced equipment and technology, an exquisite reaction path is designed. A specific catalyst is often used to accelerate the reaction process and reduce the severity of the reaction conditions. For example, with a new type of catalyst, the reaction that originally required high temperature and high pressure can be carried out under mild conditions. This method is accurate and efficient, and can be prepared on a large scale. However, it requires extremely high equipment and technicians, and the research and development and preparation of catalysts are not easy.
The method of making this substance has its own strengths and weaknesses. The ancient method emphasizes experience, the extraction is natural, and the modern method relies on technology. To obtain the best method, it is necessary to consider the specific situation, such as the requirements for yield and purity, the limitations of cost, and the available resources and technologies.
