What are the physical properties of M-dichloro Benzene?
M-dichlorobenzene, also known as m-dichlorobenzene, has the following physical properties:
At room temperature, this substance is in the state of a colorless transparent liquid with an aromatic odor. Viewed, it can be seen that it is clear, like glass. Its melting point is quite fixed, about -24.7 ° C, just like the rule of the solar term, at which time the state of matter changes. The boiling point is about 173.4 ° C. When the temperature reaches this point, the liquid boils and turns into a gaseous state, such as the change of clouds.
The density of this substance is about 1.2884g/cm ³ compared with water, which is heavier than water. If the two are mixed, it will sink to the bottom of the water, like a stone falling into the abyss. And slightly soluble in water, just like oil floats in water, it is difficult to blend, and only a few molecules can be dispersed in it. However, it is soluble in organic solvents such as ethanol, ether, and chloroform, just like a wanderer returning home, and it is insoluble with similar solvents.
Furthermore, it has a certain volatility. In the air, the molecules gradually dissipate, and the smell gradually becomes audible. And due to volatility, a certain concentration of steam can be formed in a sealed space. Its vapor is heavier than air and can spread to a considerable distance at a lower place. In case of open flames and high heat, it can cause combustion and explosion. If dry wood encounters fire, it is very dangerous. The physical properties of M-dichlorobenzene are all its inherent characteristics. In many fields such as industry and scientific research, they have unique uses due to these properties, and some of them are potentially dangerous. Therefore, they should be treated with caution and should not be ignored.

What are the chemical properties of M-dichloro Benzene?
M-dichlorobenzene is an organic compound. In its molecular structure, there are dichlorine atoms in the meso-site above the benzene ring. This substance has unique physical properties. It is a colorless liquid at room temperature, has a pungent odor, and is insoluble in water, but soluble in most organic solvents, such as ethanol, ether and the like.
On its chemical properties, the conjugated system of M-dichlorobenzene ring has aromatic properties. Its benzene ring can undergo electrophilic substitution reaction, and the chlorine atom is the ortho and para-site locator. Although it has electron-absorbing induction effect, due to the conjugation effect, the electron cloud density of the benzene ring is relatively high in the ortho and para-site, so the electrophilic reagent is easy to attack the ortho and para-site. However, due to the fact that the dichlorine atoms are all in the meso-site, it is difficult to form the meso-substitution reaction products.
For example, if it is co-heated with a mixed acid of nitric acid and sulfuric acid, a nitrification reaction can occur to form m-dichloronitrobenzene. This reaction process is that the mixed acid produces nitro-cation (NO ²), which attacks the benzene ring as an electrophilic reagent and is converted through a series of intermediates to obtain the final product.
In addition, the chlorine atom of M-dichlorobenzene can undergo a substitution reaction. Under suitable conditions, such as the presence of a strong base and heating, the chlorine atom can be replaced by nucleophiles such as hydroxyl groups and amino groups to generate corresponding substitution products. This substitution reaction is carried out according to the nucleophilic substitution mechanism, and solvent, temperature and other conditions have an impact on the reaction rate and product selectivity.
In addition, M-dichlorobenzene can also participate in some other reactions, such as the reaction with metal-organic reagents. It has a wide range of uses in the field of organic synthesis and can be used as an important intermediate for the synthesis of complex organic compounds.

What are the precautions for M-dichloro Benzene during production?
During the production process of M-dichlorobenzene, all kinds of things should be paid attention to. Safety is the first priority, and this is the foundation of all things. M-dichlorobenzene is toxic and irritating, and workers should be fully protected during operation. Protective clothing, protective gloves and goggles must be worn to prevent it from touching the skin and eyes. It is also suitable for working in well-ventilated places. If it is in a closed place, an effective ventilation device should be installed to quickly discharge exhaust gas to avoid the risk of poisoning caused by its accumulation.
This is related to storage. M-dichlorobenzene should be stored in a cool, dry and well-ventilated place, away from fire and heat sources. Because of its flammability, it needs to be stored separately from oxidants and edible chemicals, and should not be mixed to prevent biochemical reactions from endangering. And the storage area should be properly equipped to contain leaks and fire fighting equipment to deal with in case.
Furthermore, the production equipment needs to be strictly controlled. The equipment should be intact and there is no risk of leakage. Regular inspection and maintenance to ensure its stable operation. In the links of material transportation and reaction, precise temperature control, pressure control and speed control, in accordance with established process procedures, and cannot be changed without authorization. Due to changes in temperature, pressure and speed, or abnormal reactions, safety accidents may result.
Repeat, waste disposal should not be ignored. Waste containing M-dichlorobenzene produced in production should not be disposed of at will. It must be collected, stored and disposed of properly in accordance with environmental regulations. Or it can be disposed of harmlessly in a professional treatment plant, or recycled and reused to minimize its harm to the environment.
In addition, strict training must be given to production personnel. Make them familiar with the nature, hazards and emergency treatment methods of M-dichlorobenzene. And often perform emergency drills. In case of leaks, fires and other emergencies, workers can respond calmly and take effective measures to reduce losses and hazards to a minimum.

What is the environmental impact of M-dichloro Benzene?
M-dichlorobenzene (m-dichlorobenzene), which has a particularly important impact on the environment. M-dichlorobenzene is volatile, and in the atmosphere, it may participate in photochemical reactions. Under sunlight exposure, it can react with active substances such as hydroxyl radicals in the atmosphere, resulting in a series of secondary pollutants, which have adverse effects on air quality, reduce visibility, and even cause hazards such as photochemical smog.
In the aquatic environment, m-dichlorobenzene is insoluble in water, but it is easily adsorbed on suspended particles, or settles to the sediment at the bottom of the water. If it enters the aquatic ecosystem or is ingested by aquatic organisms, it will produce bioaccumulation and amplification effects through the food chain, posing a threat to the survival and reproduction of aquatic organisms and reducing biodiversity.
In soil, m-dichlorobenzene either escapes into the atmosphere due to volatilization or leaches into groundwater. It persists in the soil, or affects the community structure and function of soil microorganisms, hinders the decomposition of organic matter and nutrient cycle in the soil, and then affects the growth and development of plants, resulting in damage to crop yield and quality.
m-dichlorobenzene has a negative impact on the air, water, soil and ecosystem of the environment. Therefore, during its production, use and disposal, it is necessary to treat it with caution and take appropriate measures to reduce its harm to the environment.
