What are the main uses of diethylbenzene?
Diacetylphine, that is, heroin, is a drug, and its harm is so great that it has no legitimate use at all.
Heroin is highly toxic, and once people are infected, they are very easy to become addicted, causing irreversible damage to the body. When you first taste it, you may have a short-term euphoria, and then you fall into the abyss of pain. It is very harmful to the nervous system, causing mental weakness, blurred consciousness, memory loss, decreased thinking ability, and even mental disorders such as hallucinations and delusions.
In the cardiovascular system, it can cause arrhythmia, sudden drop in blood pressure, and in severe cases, heart failure, endangering life. The respiratory system is also deeply affected, inhibiting the respiratory center, causing breathing to become shallow and slow, and even respiratory arrest. Long-term use, the immune system is seriously damaged, the body's disease resistance has dropped sharply, and various diseases have taken advantage of it, such as pneumonia, hepatitis, AIDS, etc.
And because of drug use, it costs a lot of money, which often makes the addict go bankrupt. In order to obtain drug money, they are willing to take risks and commit crimes such as theft and robbery, which disrupt social order and undermine social stability. Families are also fragmented, relatives are separated, and family relationships are broken.
Therefore, heroin has absolutely no beneficial use. The whole society should be highly vigilant against it, resolutely resist it, and protect a healthy and harmonious social environment together.
What are the physical properties of diethylbenzene?
Diacetonitrile, also known as ethane cyanide, is an organic compound with a molecular formula of $C_4H_6N_2 $. The following are the physical properties of diacetonitrile:
- ** Physical state and color **: Under normal conditions, diacetonitrile is a colorless and transparent liquid. It is pure and clear in appearance, with no visible impurities or heterochromia. This physical appearance makes it easy to identify and handle in many application scenarios.
- ** Odor **: It has a weak special smell, but the smell is not pungent or uncomfortable, and it needs to be detected by close sniffing. This odor characteristic also affects its use and storage in different environments. < Br > - ** Boiling point **: The boiling point is about 242 ° C. A relatively high boiling point indicates that the intermolecular force is strong. To transform it from liquid to gaseous, more energy needs to be input. This property allows it to maintain a liquid state at higher temperatures. It can be used as a stable reaction medium or solvent in some chemical reactions or industrial processes that require high temperature treatment.
- ** Melting point **: The melting point is about -21 ° C. The relatively low melting point means that diacetonitrile is liquid at room temperature, making it easier to pour, mix and participate in various reactions, which brings convenience to practical operation. < Br > - ** Density **: The density is about 0.944g/cm ³, which is slightly less than the density of water. If diacetonitrile is mixed with water, diacetonitrile will float on the water surface, and this density difference can be exploited in the separation and purification process.
- ** Solubility **: Diacetonitrile can be miscible with various organic solvents such as ethanol and ether, showing good solubility. It can be uniformly mixed with many organic compounds to form a homogeneous system, which is conducive to the progress of chemical reactions and the transfer and diffusion of substances. However, its solubility in water is limited, and this difference in solubility also helps to separate and purify diacetonitrile by liquid-liquid extraction and other methods.
What are the chemical properties of diethylbenzene?
Diethyl ether, the name of the ancient or unknown, has its chemical properties and is listed below.
Diethyl ether is a colorless and transparent liquid with a special odor at room temperature and pressure, which is highly volatile. This property is like the easy dissipation of light smoke. Its vapor is heavier than air and can accumulate at low places. Its boiling point is quite low, about 34.6 ° C, and it quickly turns into a gaseous state when heated, just like thin ice melts quickly when warm.
The solubility of diethyl ether is also unique, and it can be miscible with many organic solvents, such as ethanol, acetone, chloroform, etc. in any ratio, but its solubility in water is very small, just like oil and water, which are difficult to blend.
Its chemical properties are relatively stable, but under certain conditions, it can also exhibit an active state. Diethyl ether is relatively stable to acids and bases. If it encounters strong acids, such as concentrated sulfuric acid, it can react when heated to form products such as ethyl hydrogen sulfate.
Diethyl ether is flammable. It is easy to burn and explode in the air when exposed to open flames and hot topics. Its steam and air can form an explosive mixture with an explosion limit of 1.9% - 36.5% (volume fraction). This property is like the encounter between fire and medicine, and it cannot be careless.
In addition, the peroxide problem of diethyl ether also needs attention. During long-term storage, if exposed to air and under conditions such as light, diethyl ether can be slowly oxidized to form peroxides, which are unstable and prone to explosions when heated or impacted, like hidden dangers in the dark.
What are the production methods of diethylbenzene?
There is a way to study the two-dimensional Hu. The ancient goodness of this one, each has its own, and many are kept secret. However, the ancient books can also obtain their outline.
First, it is very important to expect. Take the best Hu, and the one with the right grain and color is the best. As the "Compilation of Hundred Herbs" says: "The goodness of the two-dimensional Hu begins with the fine selection of the beard." It is necessary to go to the place to check the quality of the Hu, so as to ensure its quality.
Second, the method of processing, there is also a wonderful truth. First soak the Hu in water, and it is appropriate to make it. For a long time, it has a light taste, and it is short and penetrating. Soak the beard, put it in a kettle, and fry it slowly. Control of the heat, especially the thing. The fire is fierce and the beard is burnt, and the taste is not right; the fire is slightly cooked, and the fragrance is not good. "Secret Essentials" says: "Fried Eryou Hu, such as, It is necessary to use the secret equipment of Qiandao to prevent it from getting damp and damp. The "Brief Introduction to Tibetan Objects" says: "Eryou Hu, seek to make Qiandao dry, and keep your mouth secret, so that it can last for a long time and not be damaged." In this way, the fragrance, taste, and effect of Eryou Hu can all be preserved.
It is the secret of Eryou Hu, and the materials are hidden until they are hidden, and they are linked to each other. All of them are the wisdom and efforts of the ancient world. You need to study them carefully to get the truth.
What are the precautions for diethylbenzene during storage and transportation?
In the time of storage and transportation, pay attention to all things. The second one is a container, its quality is pottery or porcelain, and it has a specific shape. When storing and transporting, it is necessary to be careful.
When storing, the first environment. It is advisable to choose a dry, cool and ventilated place. If it is in a humid place, the body is prone to mildew, which damages its appearance, and even affects the stored things. If the environment is dry and hot, the stored things may deteriorate due to excessive temperature. Therefore, finding a suitable storage place is the top priority.
Furthermore, the stored things should be comparable to the characteristics of the stain. If the stain has fine pores, it is not suitable to store liquids to prevent leakage. If the storage is perishable, it needs to be protected as appropriate, or wrapped in silk or lined with dried leaves to keep it longer.
When transporting, packaging is extremely critical. First use soft grass, cotton wool, etc. to pad around the box to cushion and prevent collision. Then place it in a sturdy box, and fill the gaps in the box with soft objects, so that the box is stable and will not shake and collide. Handlers should also be careful, lift and handle it lightly, and do not act recklessly. If the road conditions are not good on the way, you need to pay more attention to prevent damage to the body.
All of these are essential for Eryou's storage and transportation. Those who act should be cautious to ensure that the two unites and their stored items are intact.
