What are the effects of 1,2-dichlorobenzene on the environment?
1% 2C2-dichlorobenzene is an organic compound that has an impact on many aspects of the environment, as detailed below:
** Atmospheric environment **: If 1% 2C2-dichlorobenzene evaporates into the atmosphere, it will participate in photochemical reactions. Under light, it can react with active substances such as hydroxyl radicals in the atmosphere to generate a series of secondary pollutants, such as ozone. If the concentration of ozone is too high, it will cause photochemical smog, which not only endangers human health, causes respiratory discomfort, eye tingling and other symptoms, but also causes damage to plants, affecting their photosynthesis and growth. Moreover, 1% 2C2-dichlorobenzene has a certain residence time in the atmosphere, which can be transported over long distances by means of atmospheric circulation, thus expanding the scope of pollution.
** Water Environment **: Once 1% 2C2-dichlorobenzene enters the water body, it will be deposited at the bottom of the water because it is insoluble in water and has a higher density than water. This will not only cause direct toxicity to aquatic organisms, but also interfere with the ecological balance of the water body. For aquatic plants, it will affect their absorption of nutrients and the process of photosynthesis; for aquatic animals, it may damage their nervous system, reproductive system, etc., resulting in decreased reproductive capacity and abnormal development. In addition, if sewage containing 1% 2C2-dichlorobenzene is discharged into the natural water body without effective treatment, it will also pollute drinking water sources and threaten human drinking water safety.
** Soil environment **: When 1% 2C2-dichlorobenzene enters the soil, it will adsorb on the surface of soil particles, affecting the structure and function of microbial communities in the soil. The growth and metabolism of some microorganisms will be inhibited, which will then interfere with the normal material cycle and energy conversion process in the soil. For example, it affects the decomposition of organic matter and nutrient release in the soil, resulting in reduced soil fertility. Moreover, it degrades slowly in the soil and will remain for a long time, causing pollution to subsequent crops, and ultimately endangering human health through the enrichment of the food chain.
In summary, 1% 2C2-dichlorobenzene can have a negative impact on environmental factors such as atmosphere, water, soil, etc. During its production, use, and disposal, appropriate measures must be taken to reduce the harm to the environment.

What are the physical properties of 1,2-dichlorobenzene?
1% 2C2-dioxane, also known as 1% 2C2-dioxane, is a colorless and transparent liquid that is widely used in the chemical industry. Its physical properties are as follows:
- ** Appearance and Properties **: Colorless liquid with ether-like odor. This appearance characteristic makes it easy to identify and operate in many reaction systems. Although the ether-like smell is unique, it should also be paid attention to when using it, because it may have a certain impact on the human body.
- ** Boiling point **: about 101.3 ° C. This boiling point determines the choice of conditions in operations such as heating separation. The relatively moderate boiling point makes it easier to achieve separation and purification in conventional experiments and industrial production equipment.
- ** Melting point **: 11.8 ℃. The low melting point means that it is mostly liquid at room temperature, which is easy to transport and use. In terms of storage conditions, it is generally normal temperature environment, and no special low temperature storage equipment is required.
- ** Solubility **: It is miscible with water and can be miscible in most organic solvents. Good solubility makes it an excellent solvent. In organic synthesis, it can not only dissolve organic compounds, but also fuse with aqueous systems, promoting the progress of some heterogeneous reactions, which greatly expands its application range.
- ** Density **: Relative density (water = 1) 1.04. The density is similar to that of water, and when it comes to liquid-liquid separation and other operations, it needs to be effectively separated according to other physical properties or chemical methods.
- ** Stability **: Stable. This property ensures that it is not prone to spontaneous decomposition or deterioration under general storage and use conditions, providing a strong guarantee for its long-term storage and wide application. However, under specific conditions such as high temperature and the presence of strong oxidizing agents, it still needs to be handled with caution to prevent dangerous reactions.

What are the chemical properties of 1,2-dichlorobenzene?
1,2-Dichlorobenzene is an organic compound. Its properties have a number of characteristics, so let me come to you.
1,2-Dichlorobenzene is a colorless and volatile liquid with a pungent and aromatic smell. It boils at about 180.5 ° C and condenses at -17.5 ° C. This substance is slightly soluble in water, but it can be miscible with organic solvents such as ethanol, ether, and chloroform.
In terms of its chemical activity, the benzene ring of 1,2-dichlorobenzene exhibits unique reactivity due to the presence of chlorine atoms and the change of electron cloud density. In the electrophilic substitution reaction, the chlorine atom is an ortho and para-locator, which will guide the electrophilic reagent to attack the ortho and para-site of the benzene ring. For example, in the nitration reaction, a mixture of 2,3-dichloronitrobenzene and 4,5-dichloronitrobenzene can be formed.
Its stability is quite high, and it can be stored for a long time at room temperature and pressure without easy spontaneous decomposition. In case of hot topics, open flames or strong oxidants, it is also dangerous, or cause combustion or even explosion.
1,2-dichlorobenzene has certain toxicity. If the human body comes into contact with it, or enters the body through respiratory inhalation, skin absorption, etc., it can damage the nervous system, liver and other organs.
In industry and life, 1,2-dichlorobenzene is often used as a solvent to dissolve resins, rubbers and other substances; it is also used in organic synthesis, and is an important raw material for the preparation of pesticides, medicines and dyes. However, due to its toxicity and potential harm, it should be used with caution and strictly follow safety procedures to prevent accidents.

What are the production methods of 1,2-dichlorobenzene?
1% 2C2-dibromoethane, the ancient name "ethylene dibromide", its preparation method is as follows:
First, ethylene and bromine are used as raw materials to cause an addition reaction between the two. "Kaogong Ji" said: "When the two things are combined, there must be changes." Ethylene meets bromine, the double bond breaks, and the bromine atom is added to the carbon at both ends, which is the wonder of addition. The reaction formula is:\ (C_ {2} H_ {4} + Br_ {2}\ rightarrow C_ {2} H_ {4} Br_ {2}\). During the reaction, the ethylene is slowly introduced into the bromine-containing carbon tetrachloride solution, and the reddish-brown of the solution fades away, which is the sign of the reaction.
Second, ethanol can be started from ethanol, first co-heating with concentrated sulfuric acid. According to Tiangong Kaiwu, "the energy variable of fire", ethanol is dehydrated into ethylene when concentrated sulfuric acid and\ (170 ^ {\ circ} C\), and the reaction is:\ (CH_ {3} CH_ {2} OH\ xrightarrow [170 ^ {\ circ} C] {concentrated sulfuric acid} CH_ {2} = CH_ {2}\ uparrow + H_ {2} O\). After obtaining ethylene, add it with bromine to prepare 1% 2C2-dibromoethane.
Third, starting with 1-bromoethane, it is co-heated with sodium hydroxide alcohol solution, and an elimination reaction occurs to debrominate hydrogen to produce ethylene. "Tiangong Kaiwu" has the cloud "the change of matter, or the removal of its excess". This elimination reaction is an example of debromination of hydrogen. The reaction formula is:\ (CH_ {3} CH_ {2} Br + NaOH\ xrightarrow [\ triangle] {alcohol} CH_ {2} = CH_ {2}\ uparrow + NaBr + H_ {2} O\). Ethylene is then added with bromine to obtain 1% 2C2-dibromoethane.
All the above production methods are based on the principle of chemical changes, and 1% 2C2-dibromoethane is prepared from different raw materials through addition, elimination and other reactions.
