1,3-Dichlorobenzene; What are the physical properties of m-dichlorobenzene?
1,3-Dichlorobenzene, also known as m-dichlorobenzene, is an organic compound. It is a colorless and transparent liquid with an irritating odor at room temperature and pressure. It is insoluble in water and miscible in most organic solvents such as ethanol, ether, and chloroform. The following is a detailed description of its physical properties:
1. Appearance and odor
It is a colorless and transparent liquid with an irritating odor. This odor is due to its molecular structure containing chlorine atoms, which irritates the olfactory nerve.
2. Melting point and boiling point
- ** Melting point **: The melting point of m-dichlorobenzene is about -24.7 ° C. At this temperature, it changes from liquid to solid. Due to the increase in intermolecular forces at low temperatures, the molecular activity is limited, resulting in an ordered lattice structure.
- ** Boiling point **: The boiling point is about 173.4 ° C. At this temperature, the liquid absorbs enough energy, and the thermal motion of the molecules intensifies enough to overcome the intermolecular forces and transform from liquid to gaseous state.
3. Density
The density is about 1.2884g/cm ³ (20 ° C), which is greater than the density of water by 1g/cm ³, so it will sink in water. This is because the molecule contains chlorine atoms with relatively large atomic mass, resulting in an increase in unit volume mass.
4. Solubility
- ** Water **: m-dichlorobenzene is insoluble in water. Because it is a non-polar molecule and water molecules are polar molecules, according to the principle of "similarity and miscibility", the polarity is different, and the two are difficult to dissolve each other.
- ** Organic solvent **: It can be miscible with most organic solvents such as ethanol, ether, and chloroform. Because most of these organic solvents are non-polar or weakly polar, they are similar to the intermolecular force of m-dichlorobenzene and can be dispersed and mixed with each other.
5. Volatility
m-dichlorobenzene has a certain volatility. At room temperature and pressure, some liquid molecules can obtain enough energy to escape from the liquid surface and become gaseous molecules. Its volatility is affected by factors such as temperature, surface area, and air flow. The higher the temperature, the larger the surface area, and the faster the air flow, the faster

1,3-dichlorobenzene; is m-dichlorobenzene chemically stable?
The chemical properties of 1,3-dibromobenzene (m-dibromobenzene) are relatively stable. In its molecular structure, the benzene ring has a conjugated large π bond, which gives it a certain stability.
In terms of bond energy, the carbon-carbon bond in the benzene ring is not alternating single and double bonds, but a unique bond between single and double bonds. The bond energy is large, and high energy is required to destroy this structure. Although the bromine atom in m-dibromobenzene has a certain electron absorption, which reduces the electron cloud density of the benzene ring, the overall conjugated system of the benzene ring has not been seriously damaged and remains relatively stable.
Under normal conditions, m-dibromobenzene is not prone to violent reactions. For example, at room temperature and pressure, it is difficult to chemically react with common reagents such as water, dilute acids, dilute bases, etc. However, under specific conditions, such as high temperature and the presence of catalysts, it can also participate in some reactions, such as electrophilic substitution reactions. Because the bromine atom is an ortho-para locator, although the activity of the benzene ring is slightly reduced, it can still guide new substituents into the ortho-site or para-site of the benzene ring. But in general, compared with some active organic compounds, the chemical properties of 1,3-dibromobenzene are stable.

1,3-Dichlorobenzene; what are the precautions in the production process of m-dichlorobenzene?
1% 2C3-dibromobenzene and m-dibromobenzene are produced as follows:
First, the selection of raw materials and the importance of pretreatment. To obtain a pure product, the raw materials used must have high purity. Taking benzene as an example, impurities must be removed, because it may cause side reactions, which will damage the purity and yield of the product. The pretreatment steps or involve distillation, extraction and other methods to ensure that the raw materials meet the production standards.
Second, the precise control of the reaction conditions is crucial. Temperature, pressure and catalyst are all key factors affecting the reaction. To synthesize 1% 2C3-dibromobenzene and m-dibromobenzene, iron bromide or iron powder are mostly used as catalysts, and bromine and benzene react under specific conditions. If the temperature is too high, side reactions occur frequently, such as the formation of polybrominates; if the temperature is too low, the reaction rate will be slow, time-consuming and inefficient. Therefore, it is necessary to find a suitable temperature and pressure range according to the reaction characteristics to ensure a smooth and efficient reaction.
Third, safety protection cannot be ignored. Bromine is highly corrosive and toxic, and it is easy to volatilize bromine-forming vapor, which endangers the human body and the environment. During production, a complete ventilation system must be built to remove bromine vapor. Operators also use protective clothing, goggles, gas masks, etc., to prevent bromine liquid from splashing and inhaling bromine gas. At the same time, properly dispose of waste bromine liquid and bromine-containing waste gas, and comply with environmental regulations.
Fourth, the separation and purification of products are also key. After the reaction is completed, the product is often mixed with unreacted raw materials, catalysts and by-products. Appropriate separation techniques, such as distillation, recrystallization, extraction, etc., must be used to obtain high-purity products. Distillation is separated according to the difference in boiling point of each component; recrystallization is purified by different solubility of substances; extraction is dependent on the difference in solubility of solutes in immiscible solvents to achieve separation.
Fifth, the maintenance and inspection of equipment should not be slack. During the production process, equipment is exposed to corrosive substances for a long time and is prone to corrosion damage. Regularly inspect equipment, check pipelines, valves, reactors and other components, and replace damaged parts in time to ensure normal operation of equipment and avoid safety accidents such as leakage.

1,3-Dichlorobenzene; what are the environmental effects of m-dichlorobenzene?
1,3-Dichlorobenzene, also known as m-dichlorobenzene, is an organic compound. Its impact on the environment is described as follows:
Atmospheric environment
m-dichlorobenzene is volatile, escapes to the atmosphere, through photochemical reactions, or generates secondary pollutants such as ozone, resulting in air quality degradation. And its migration and transformation in the atmosphere can be transported over long distances and expand the scope of pollution.
Aquatic environment
If m-dichlorobenzene enters the water body, it is insoluble in water, but it can be adsorbed by suspended particles and settle to the sediment at the bottom of the water. In water, it may be toxic to aquatic organisms, damage their physiological functions, and inhibit reproduction and growth. Such as causing diseases in the gill tissue of fish, affecting respiration; on plankton, or destroying its cell structure, causing population number change.
Soil environment
m-dichlorobenzene enters the soil and will be adsorbed by soil organic matter, affecting soil physicochemical properties. It may inhibit the activity of microorganisms in the soil and interfere with the normal material cycle and energy conversion process in the soil. For example, it affects the transformation of nutrients such as nitrogen and phosphorus in the soil, which decreases soil fertility and then affects plant growth and development.
Comprehensive Effects on the Ecosystem
The pollution of m-dichlorobenzene will break the balance of the ecosystem. In the food chain, low concentrations of m-dichlorobenzene can gradually accumulate in organisms through bioenrichment, and the concentration is gradually enlarged. For example, small fish ingest plankton containing m-dichlorobenzene, large fish prey on small fish, and eventually humans or other organisms at the top of the food chain, due to long-term consumption of contaminated organisms, their health is threatened, causing liver, kidney damage, and nervous system diseases.
