First, it can be used as an organic solvent. It can dissolve many organic compounds. In the preparation of paints, paints and adhesives, it is often used as a solvent to help disperse and dissolve various ingredients, so that the paint is evenly applied, the paint film is flat, and the product performance is enhanced.
Second, it is very powerful in the synthesis of pesticides. It is an important intermediate in the synthesis of some pesticides and participates in the reaction to build the molecular structure of pesticides, which is essential for killing pests and protecting the growth of crops.
Third, it also contributes to the field of medicine. It provides raw materials or intermediates for the synthesis of certain drugs, helps the construction of active pharmaceutical ingredients, and contributes to human health protection.
Fourth, in the electronics industry, it is used to clean electronic components. Because of its good solubility, it can effectively remove oil and impurities on the surface of components, and ensure the performance and stability of electronic components.
Although o-dichlorobenzene is not listed in "Tiangong Kaiwu", it plays an indispensable role in today's industries, agriculture, medicine, electronics and other fields, greatly promoting social development and progress.
Its boiling point is quite high, about 180.4 ° C. At this temperature, the liquid will turn into a gaseous state. The melting point is -17.5 ° C. When the temperature drops to this temperature, it changes from liquid to solid state. The relative density (water = 1) reaches 1.306, which is heavier than water, so when poured into water, it must sink to the bottom.
The vapor density (air = 1) of o-dichlorobenzene is 5.0, which is heavier than air, and its vapor is easy to accumulate in low places. This substance is slightly soluble in water and can only dissolve about 0.08 grams in 100 grams of water. However, it can be miscible in organic solvents such as ethanol, ether, and chloroform, and it dissolves seamlessly.
In addition, the flash point of o-dichlorobenzene is 65 ° C. It is very easy to burn in case of open flame and hot topic, and its vapor is mixed with air to form an explosive mixture. There is a risk of explosion in case of fire source. Therefore, when using and storing, special attention should be paid to fire and explosion prevention.
The first raw material, the purity of the raw material, is related to the quality of the product. When selecting materials, when seeking high quality and purity, there must be less impurities. If the raw material is not pure, the quality of the production of orthogonal dichlorobenzene will be inferior, or the reaction will be biased.
Times and reaction conditions. Temperature, pressure, and catalyst are all important. Temperature control must be accurate. If the temperature is too high, or side reactions will occur, the yield will drop and the impurity will increase; if the temperature is too low, the reaction will be slow and take a long time. Pressure should not be ignored, and proper pressure can promote the reaction. The choice and use of catalysts can change the rate of reaction and improve the yield. Improper catalysts may make the reaction not meet expectations.
Furthermore, the quality of the equipment is also critical. Reactors, pipelines, etc., must be corrosion-resistant and pressure-resistant. Due to the production of orthogonal dichlorobenzene, or materials involving strong corrosion, the equipment is not resistant, and it is easy to cause leakage, endanger safety, and damage the product. If the pipeline is not smooth, the material transmission will be blocked, which will affect the order of production.
Safety protection must not be taken lightly. During production, orthogonal dichlorobenzene and related materials may be toxic and flammable. Operators should be in front of protective equipment, such as gas masks and fire clothing. The workshop should be equipped with ventilation and fire protection devices to prevent accidents. Waste gas, waste water, waste residue, must be properly disposed of, in accordance with environmental regulations, pollution-free environment.
The rules of operation must also be strictly observed. Operators must be familiar with the process of the process and operate according to the rules. Do it at will, prone to accidents. Training is indispensable, so that operators know the safety and operation methods. In this way, the production of orthogonal dichlorobenzene can be orderly, safe and efficient.
First talk about the atmosphere. If this substance volatilizes in the atmosphere, it can interact with free radicals through photochemical reactions. Or generate secondary pollutants such as ozone, which can cause air quality deterioration at low altitudes, endanger human respiration, and cause respiratory diseases. And it remains in the atmosphere, can be transmitted over a long range, and has a wide range of effects.
As for water. If orthodichlorobenzene into the water body, it is difficult to be rapidly degraded by microorganisms because it has a certain chemical stability. Aquatic organisms are easy to accumulate this substance, causing damage to their own physiological functions. And it is transmitted in the middle of the food chain to the top organisms, and its concentration may increase significantly, endangering the ecological balance.
Soil is also affected by it. This substance seeps into the soil, which will change the physical and chemical properties of the soil, affect the structure and function of the soil microbial community. Or inhibit the growth of beneficial microorganisms, resulting in a decrease in soil fertility, which in turn affects the absorption of nutrients by plant roots and hinders plant growth and development.
In short, orthodichlorobenzene has adverse effects on many elements of the environment and should be handled with caution to ensure the safety of the environment.
In the past, the price of o-dichlorobenzene varied significantly in different seasons and regions. When market demand is strong and supply is slightly tight, its price often rises; if supply exceeds demand, the price will decline. Looking at past market conditions, its price may fluctuate between thousands of yuan and more than 10,000 yuan per ton.
If you want to get an accurate price, you must look at the reality of the current market. Consult the chemical product trading market, chemical raw material suppliers, or consult a professional chemical information platform to obtain the latest and exact price range. Don't just judge today's market based on past prices. The market is constantly changing, and it is necessary to track it in real time to grasp the true meaning of its price.
In industry, n-dichlorobenzene can be used as a solvent. Because of its good solubility and solubility of many organic substances, it is often used in the manufacture of paints, coatings, glues, etc. Taking paints as an example, n-dichlorobenzene can make pigments evenly dispersed, making paints more evenly coated and improving their quality. It can also be used in the rubber industry as an auxiliary for rubber processing, assisting rubber plasticization, mixing, and improving rubber processing performance.
In agriculture, n-dichlorobenzene can be used as a pesticide raw material. It can be used to make pesticides, fungicides and other pesticides. The insecticide made from n-dichlorobenzene can remove crop pests, protect the growth of crops, and ensure a bumper grain harvest. Its bactericidal effect can also prevent agricultural crop diseases and maintain the balance of agricultural ecology.
In the field of medicine, n-dichlorobenzene also has its uses. It can be used as a drug intermediate and participates in many drug synthesis. Taking a certain type of antibacterial drug as an example, n-dichlorobenzene is an important synthetic raw material. After a series of chemical reactions, it becomes a drug with antibacterial activity, which can cure diseases and save people and relieve the suffering of patients.
Furthermore, n-dichlorobenzene is also indispensable in the dye industry. It can be used as a raw material for dye synthesis to help dye colorful fabrics, which meets the needs of the public for the beauty of textiles. And in the electronics industry, it can clean electronic components, remove oil and impurities, and N-dichlorobenzene has a variety of uses and is of great value in various industries.
First of all, its appearance, o-dichlorobenzene is a colorless to light yellow transparent liquid at room temperature. Its shape is clear, and it looks shiny, just like the clarity of a clear spring. Its smell is unique and has an aromatic smell, but there is a pungent smell in this fragrance, and you can smell its special smell.
When it comes to the boiling point, the boiling point of o-dichlorobenzene is about 180.4 ° C. At this temperature, the liquid gradually turns into a gas and rises. Its melting point is about -17.5 ° C. When the ambient temperature drops to this temperature, the originally flowing liquid solidifies into a solid state.
In terms of density, o-dichlorobenzene has a higher density than water, about 1.306 (20 ° C), so if it is mixed with water, it will sink to the bottom of the water. Its solubility is also special, slightly soluble in water, just like the difficulty of oil and water. However, in organic solvents such as ethanol, ether, and chloroform, it can be miscible, like a fish getting water, and it can blend seamlessly.
Furthermore, the volatility of o-dichlorobenzene cannot be underestimated. At room temperature and pressure, it can evaporate slowly and dissipate in the air. And because of its flammability, it can be burned in case of open flame or hot topic. When burning, the flame is bright and accompanied by black smoke. Its steam and air can form an explosive mixture. In case of open flame and high heat energy, it can cause combustion and explosion. Therefore, when using and storing, it is necessary to be extremely cautious to prevent it from causing disasters.
The above are all the physical properties of o-dichlorobenzene. Only then can we know its characteristics and use it properly to avoid its harm.
The main reason for dichlorobenzene is an aromatic compound. Among its molecules, benzene is characterized and its properties lay the foundation. Benzene has a special common system, and the distribution of the sub-cloud is uniform, which makes the molecular energy of the whole molecule decrease. However, the substitution of chlorine atoms has an impact on the distribution of the sub-cloud of benzene, but it has not been determined at all.
Under normal conditions, dichlorobenzene is a clear solution and has a special taste. Its chemical activity is related to some compounds with high functional activity. For example, in the general environment, it is not easy to rapidly react to the usual components in water and air. If it is placed in the general environment, the short-term solution, the external solution and the chemical formation are clearly transformed, which is sufficient to determine the underlying properties of this product.
However, the performance is not guaranteed. In case of special components such as high-temperature, oxidation, or original materials, dichlorobenzene will also be reversed. Under high temperature, the molecular energy increases and the activity of the chemical increases, which may lead to reactions such as the rearrangement of substituents and benzene. Oxidation, such as the mixture of sulfuric acid and nitric acid, can cause nitrification and reverse reaction, breaking its original stability. For
, under normal conditions, the chemical properties of dichlorobenzene are determined; but under specific conditions, its qualitative properties are broken and the chemical activity is exhibited.
The reaction conditions are also critical. When the temperature is precisely controlled, if it is too high, the side reactions will be raw, and if it is too low, the reaction will be slow. Usually under suitable catalysis, the temperature is heated to a specific range to make the reaction fast and stable. The pressure also needs to be adapted, adjusted according to the reaction requirements, to ensure the stability of the system.
The choice of catalysis is about success or failure. Choosing a catalyst with high efficiency and good specificity can reduce the activation energy and promote the reaction. And pay attention to its dosage, too much or too little should not be The equipment needs to be tightly sealed to prevent chlorobenzene and chlorine from leaking, both of which are harmful and endanger safety and the environment. And stir well to make the material fully contact and react evenly.
Product separation and purification should not be ignored. Use appropriate methods, such as distillation, extraction, etc., to remove impurities to obtain high-purity o-dichlorobenzene. Every step is carefully operated to ensure smooth production and obtain high-quality products.
If the husband orthodichlorobenzene, it is dichlorobenzene. The shadow of this object in the environment cannot be ignored.
First, in the world, if dichlorobenzene is released, it can be photochemical and anti-chemical. When it is released into the air, it encounters light, oxygen, etc., or generates a lot of harmful substances, such as ozone and other secondary pollutants. Such substances do not harm the environment of the world, and the respiratory system of living things is poor. If people inhale it, the nose and throat will not be damaged, and respiratory diseases will be caused seriously.
Second, in the environment of water, dichlorobenzene will dissolve in water, but its density is high in water, so it can sink to the bottom of the water. In water, it can affect the survival of aquatic organisms. For example, if it is exposed to water containing this substance during the period, its physiological function may be affected by drying, reproduction and growth will be hindered. And this substance may be affected by biological activity, which is the most dangerous to human health.
Third, in the soil environment, dichlorobenzene can be adsorbed by the soil. Its retention in the soil affects the activity of soil microorganisms. Soil microorganisms are also responsible for soil fertility. Microbial activity is affected, the separation of soil, and the decomposition of nutrients are all affected, which affects the growth of plants. If plant growth is poor, the balance of the whole biological system is also broken.
Therefore, dichlorobenzene can be used in the environment, not in large quantities, water, and soil. Be careful to prevent its release, so as to ensure the safety of the environment.
