What are the chemical properties of 1,2,3,4-tetrachlorobenzene?
Silicon tetrachloride is an important chemical substance. Its properties have many characteristics, let me tell you one by one.
Under room temperature and pressure, silicon tetrachloride is a colorless and transparent liquid, like a clear crystal liquid, which is very beautiful to see. However, it must not be ignored, because it has a strong pungent smell, which is unbearable to smell. This smell is like an invisible warning to everyone about the danger it contains.
Its chemical activity is quite high, and it reacts quickly when it encounters water. Just like dry wood when it meets fire, it burns violently in an instant. In contact with water, Lisheng hydrogen chloride gas and silicic acid, hydrogen chloride escapes in the air, which can cause turbidity in the surrounding air and is corrosive, causing damage to many substances.
Furthermore, silicon tetrachloride in high temperature environment, the stability of the sudden drop. It is prone to chemical reactions such as decomposition, and its molecular structure falls apart under the raging heat of high temperature, and other chemical substances are derived. This property needs to be carefully considered in many fields such as chemical production.
Silicon tetrachloride is highly corrosive and can erode metals, stones and other materials. Like a sharp weapon, what is touched is often eroded by it. Metal encounters, the surface luster gradually loses, and the texture is also damaged; stone encounters, and potholes are inevitable.
In industrial production, silicon tetrachloride is widely used. However, due to its complex and dangerous chemical properties, when operating, it is necessary to be cautious and strictly follow the procedures to prevent accidents and ensure the safety and order of production.
How does 1,2,3,4-tetrachlorobenzene behave in the environment?
The behavior of silicon tetrachloride in the environment is related to physical and chemical changes.
Physically, silicon tetrachloride is a colorless transparent fuming liquid at room temperature and pressure, with a pungent odor. Its boiling point is about 57.6 ° C. It is volatile when heated and will change from liquid to gaseous and escape into the atmosphere. Because it has a certain vapor pressure, it is easy to diffuse in an open environment. If it is in water, it will sink to the bottom because its density is greater than that of water.
At the chemical level, silicon tetrachloride is chemically active. It reacts violently in contact with water to form silicic acid and hydrogen chloride gas. The reaction formula is: $SiCl_ {4} + 3H_ {2} O = H_ {2} SiO_ {3} + 4HCl $. The generated hydrogen chloride gas dissolves in water to form hydrochloric acid, which enhances the acidity of the water body and affects the pH of the water. If a large amount of silicon tetrachloride enters the water body, it will cause a serious impact on the aquatic ecology and endanger the survival of aquatic organisms. In the atmosphere, the hydrogen chloride generated by the reaction of silicon tetrachloride with water vapor will form an acid mist, which not only corrodes metals and other materials, but also forms acid rain with rain, which will damage soil, vegetation and buildings. And silicon tetrachloride can react with alkali to form silicates and chlorides.
To sum up, silicon tetrachloride in the environment is easy to diffuse due to its physical properties and active chemical properties, causing many environmental problems. Its production, storage, transportation and use process need to be properly protected and treated to reduce the harm to the environment.
What are the effects of 1,2,3,4-tetrachlorobenzene on human health?
Carbon tetrachloride is also a highly toxic chemical. Its impact on human health is not shallow.
As far as the nervous system is concerned, if people touch it, they often feel headache and dizziness at the beginning, which is a sign of nerve disturbance. If the exposure gradually deepens, or causes confusion, or even unconsciousness, it can damage the normal function of the nerves and make the nervous system out of order.
In the liver, carbon tetrachloride is particularly harmful. It can cause liver cell necrosis, and liver function is also damaged. Looking at the clinic, it can be seen that the indicators such as serum transaminase are rising, which is a clear evidence of liver invasion. Long-term exposure to this poison, liver disease or prolonged recovery, eventually becoming chronic liver disease, endangering life.
The kidneys are also difficult to avoid its damage. Carbon tetrachloride can damage the renal tubules and cause renal insufficiency. In light cases, proteinuria and hematuria may be seen, and in severe cases, it can cause kidney failure, and toxins in the body are difficult to excrete, endangering life.
And carbon tetrachloride may be carcinogenic. Although the evidence is not yet complete, studies have shown that it may be related to the occurrence of certain cancers.
And because of its volatility, it is dispersed in the air, and it is easy to absorb it in the body between human breaths. Even if the amount is small, long-term accumulation can be a disaster.
Therefore, carbon tetrachloride is very harmful to human health. On daily occasions, try your best to avoid it to prevent it from being harmful.
What are the common uses of 1,2,3,4-tetrachlorobenzene?
The common use of silicon tetrachloride is widely used in the chemical industry. First, it is an important raw material for the preparation of high-purity silicon. High-purity silicon is crucial in the semiconductor industry and is the basic material for chips, integrated circuits, etc. When preparing high-purity silicon, silicon tetrachloride is often used as the starting material, and it can be converted into high-purity silicon through complex chemical processes, such as hydrogen reduction.
Second, silicon tetrachloride can be used to make silicone compounds such as ethyl silicate. Ethyl silicate is widely used in coatings, adhesives, refractory materials and other industries. In coatings, it can enhance the adhesion, hardness and chemical corrosion resistance of coatings; in refractory materials, it can improve the strength and thermal shock resistance of refractory materials.
Third, in the field of optical fiber manufacturing, silicon tetrachloride also plays an important role. Optical fiber is the core material of modern communication, and silicon tetrachloride can be used as a raw material for the production of optical fiber preforms. After a specific vapor deposition process, silicon tetrachloride reacts with other raw materials to form a uniform glassy preform, and then the fiber is made by a wire drawing process.
Fourth, silicon tetrachloride can be used to prepare silicon dioxide aerogels. Silicon dioxide aerogels have extremely low density and excellent thermal insulation properties, and have great application potential in aerospace, building insulation and other fields. Silicon dioxide aerogels can be prepared by sol-gel method using silicon tetrachloride as a silicon source.
All of these are common uses of silicon tetrachloride and play an indispensable role in many industries.
What are the detection methods for 1,2,3,4-tetrachlorobenzene?
The detection method of carbon tetrachloride has been known in ancient times, and it is detailed for you today.
First, chemical methods can be used. In the sample, add an appropriate amount of silver nitrate solution. If carbon tetrachloride is present, white silver chloride will precipitate. Because carbon tetrachloride can dissociate chloride ions under appropriate conditions and combine with silver ions, the principle of its reaction is quite clear. Ancient warlocks, although they do not have the precise instruments of today, can still understand the characteristics of substances according to the phenomenon of chemical reactions.
Second, instrumental analysis is also a good strategy. Gas chromatography is a commonly used method. Inject the sample to be tested into a gas chromatograph, using its ability to separate different substances, carbon tetrachloride will peak at a specific time according to its own characteristics. The characteristics of this peak can help determine the presence and content of carbon tetrachloride. The beauty of this instrument is that it can accurately analyze. Although the ancients did not have this exquisite tool, it can be traced back with today's technology. This is the best method for detection.
Third, infrared spectroscopy cannot be ignored. Carbon tetrachloride has a unique molecular structure, and in the infrared spectrum, it will show a specific absorption peak. By comparing the standard infrared spectrogram, the existence of carbon tetrachloride can be confirmed. Just like the ancients identified things with unique markers, the absorption peak of infrared spectroscopy is the "mark" of carbon tetrachloride.
To sum up, the above methods can be used for the detection of carbon tetrachloride, each with its own length, and should be selected carefully according to the actual situation.
