The eggplant is cold in nature and widely used.
At the end of the diet, the eggplant has a delicious taste and can be used as a meal. Or stir-fry it, accompanied by onion and garlic ingredients, and cook it in hot oil, which is fragrant to the nose. Or stew it, and stew it with the meat. The plump aroma of the meat seeps into the eggplant, and the softness and tenderness of the eggplant are lined on the side of the meat. The two complement each other and have a mellow taste. And the eggplant has a wide range of cooking methods, such as frying, steaming, and burning, each showing its own beauty, which can satisfy everyone's different tastes.
In terms of medicinal use, the eggplant has the effect of clearing heat. In the hot season, the human body is easily disturbed by heat, and eating eggplant can slightly relieve the dryness It can also cool the blood. For some diseases caused by blood heat, such as mild bleeding caused by blood heat delusion, etc., it may have the power of auxiliary treatment. However, those with cold nature and deficiency of the spleen and stomach should eat it with caution to avoid hurting the spleen and stomach yang qi, causing abdominal pain and diarrhea.
In addition, eggplant also has considerable advantages in gardens. Its plant shape is unique, with emerald green leaves and pale purple flowers. The fruits are long or round, and the colors are mostly purple and green. Planted in the garden, it can not only harvest edible fruits, but also add color to the garden scenery, which is pleasing to the eye.
In short, the use of nightshade, dietary, medicinal, and ornamental are all involved. It is a multi-purpose thing, and it should be used reasonably according to its nature and its own condition.

Mercury and lead are the best metals. Among them, mercury is soft and heavy, and its color is blue and gray. Under normal conditions, it is malleable. If you add high pressure, it is easy to melt and liquid. Its density is large, and it sinks in water. And it has good performance, but it is difficult to do so.
Mercury, which is vulgar water, is the only gold that is often liquid. The color is white and the light is shining. Its fluidity is good, and it is slippery. Mercury evaporation is toxic and cannot be ignored. Its density is also high, insoluble in water, and the surface force is low, dripping on the plane, often gathering beads.

The color is white and slightly shiny, hard and brittle, and easy to crack and break if knocked with force. Its melting temperature is high, and its chemical properties are determined. Under normal conditions, it is not easy to make general things and biochemical reactions.
These three have their own characteristics, whether soft or liquid or brittle, and their properties are different. They all have their own uses in general techniques and methods. However, because of their characteristics, they are used carefully to avoid causing similar problems.

The combination of lead and mercury is a common combination in the ancient method of alchemy. Lead, heavy and dark in nature, belongs to water in the five elements; mercury, flowing in nature, liquid at room temperature, silver-white in color, and gold in the five elements. The two are combined, and they are desired to change in order to obtain extraordinary things.
As for methyl ether, this is something studied in modern chemistry. The chemical formula of methyl ether is\ (C_ {2} H_ {6} O\), and its chemical properties are quite characteristic. Methyl ether is flammable, and it is easy to burn and explode when exposed to open flames and hot topics. Its steam and air can form an explosive mixture, and it may cause a violent reaction when exposed to an ignition source.
From the perspective of physical properties, methyl ether is a colorless gas at room temperature and pressure, with a unique odor of ethers. Its boiling point is low, about -24.9 ° C, which makes it volatile. In terms of solubility, methyl ether is slightly soluble in water and miscible in most organic solvents.
In chemical reactions, methyl ether can undergo a variety of reactions. For example, under certain conditions, hydrolysis can be carried out to generate corresponding alcohols. It can also oxidize with some oxidants, showing the active side of its chemical properties.
The chemical properties of methyl ether are complex and changeable, and it has a wide range of uses in the chemical industry. It can be used as fuel, solvent, etc. However, when using it, it is necessary to pay attention to its flammable and explosive characteristics to ensure safety.

There are many ways to solve the problem of acetylaniline.
One of the methods is to use the raw material of aniline and acetyl chloride. When the two meet, the reaction occurs. The amino group of aniline (\ (- NH_ {2}\)) is nuclear, while the carbonyl carbon of acetyl chloride (the carbon of the chlorine phase in\ (R - CO - Cl\)) is nuclear. The solitary child on the amino nitrogen atom of aniline attacks the carbonyl carbon of acetyl chloride, and the chlorine atom is removed from the group, so acetylaniline is obtained. Its reaction speed is complete, but acetyl chloride has high activity and strong performance. It needs to be operated in a low temperature and low temperature water environment. It is easy to cause side reactions, and acetyl chloride is corrosive. The operation needs to be double careful.
Another method is to reverse the reaction of aniline and acetic anhydride. Acetic anhydride (\ (CH_ {3} CO) _ {2} O\)) is also commonly used in acetylation. The amino group of aniline attacks the carbonyl carbon of acetic anhydride, and the acetyl group moves to the nitrogen atom of aniline to form acetic acid. This reaction piece is in harmony, the side reactions are few, and the operation is easy to control. Therefore, this method is often used in the room. In addition, glacial acetic acid can be used to catalyze the reaction, such as a small amount of sulfuric acid, to promote the reaction, improve the reaction rate, and make the reaction more complete.
Furthermore, glacial acetic acid can be used to reverse aniline. Glacial acetic acid is cheap and easy to obtain, but its reaction activity is low. Both need to be added and catalyzed. Generally, sulfuric acid is used as the catalyst. Adding sulfuric acid can increase the energy of the reaction molecule, making it easier to overcome the reaction activation energy; sulfuric acid can make the carbonyl carbon of glacial acetic acid more effective, which is beneficial to the amino attack of aniline. However, the inverse equilibrium is limited, and due to its reversibility, it is often necessary to take measures to shift the equilibrium to the right, such as not removing the generated water, etc., in order to improve the yield of acetylaniline.

Those who are both alum and sand are of the genus of gold and stone, and their uses are different in nature. As for the application of methyl ether, it involves a wide range of domains.
In the field of medicine, methyl ether can be used as an anesthetic agent. In ancient times, physicians wanted to perform spells to reduce the pain of patients, and often looked for suitable methods. At this time, methyl ether may be used as hemp powder, etc., to make patients temporarily dizzy, without the disturbance of pain, and physicians can concentrate on performing spells to save people's lives.
In the world of engineering, methyl ether also has its ability. It can be used as a solvent to help blend and refine things. If you want to extract the essence and separate the sundries, the methyl ether may be effective, so that the essence can be purified and precipitated, which is beneficial to the manufacture of utensils and materials.
In the process of combustion, methyl ether can be used as fuel. Looking at today, there are many people seeking clean energy. When methyl ether burns, it generates less smoke and dust, and the emission of harmful substances is also thin. It can be used as fuel in furnaces and cars to replace traditional firewood, coal, and fuel. It can not only provide heat, make cars run, but also reduce pollution between heaven and earth, and protect the peace of nature.
And methyl ether is also indispensable in chemical synthesis. It can be used as a basic raw material, and through various methods of synthesis, it can become other useful things, for the people's livelihood and for the state, and gain a lot.
is the use of methyl ether, which is used in medicine, industry, combustion, chemical industry and other fields. Its work in the world cannot be underestimated.
