Long-term accumulation may reduce the number of fish populations and destroy the aquatic ecological balance. And its pollution will make the water body emit peculiar smell, affect the sensory properties of water, and reduce the value of the water body as a drinking water source.
2. Effects on soil
If the soil is polluted with 1% 2C2% 2C3-trichlorobenzene, it will change the physical and chemical properties of the soil. Due to its stable chemical properties, it is not easy to degrade and will accumulate residues in the soil. This will affect the growth and activity of soil microorganisms, which are essential for soil nutrient cycling and decomposition of organic matter. Inhibition of microbial activity will lead to a decrease in soil fertility and affect the absorption of nutrients by plants. Plant growth or hindrance, stunted growth, reduced yield and other conditions. Moreover, this pollutant may also migrate with rain initializing, further expanding the scope of soil pollution.

1. ** © ç †çŠ¶æ€ **
- 1% 2C2% 2C3 - trichlorobenzene is a colorless liquid at room temperature with a pungent odor. Its appearance and properties are similar to oily, because of its molecular structure, which makes the intermolecular forces present this macroscopic physical state. It is insoluble in water, but miscible in most organic solvents such as ethanol, ether, and chloroform. This difference in solubility is due to the polarity of its molecules. The polarity of 1% 2C2% 2C3-trichlorobenzene is weak, while water is a solvent with strong polarity. According to the principle of "similar miscibility", it is difficult to dissolve in water. On the contrary, the polarity of organic solvents such as ethanol and ether is relatively weak, and it is similar to the polarity of 1% 2C2% 2C3-trichlorobenzene molecules, so it can miscible with each other.

- Its melting point is -10.6 ° C, and its boiling point is 218.7 ° C. A lower melting point indicates that it can change from solid to liquid at a slightly lower temperature than normal temperature; a higher boiling point indicates that a higher temperature is required to change it from liquid to gaseous. This is closely related to the forces between molecules. There are interactions such as van der Waals forces between molecules. To overcome these forces to change the state of matter, a specific energy is required, which is reflected in the temperature of the melting point and boiling point.
3 . **导电性质**
-1% 2C2% 2C3 -trichlorobenzene is a non-electrolyte and cannot conduct electricity in aqueous solution or in the molten state. This is because there are no free-moving ions in its molecular structure, and its chemical bonds are mainly covalent bonds. Ionization does not occur under normal conditions, so it does not have the ability to conduct electricity.
4 . **密度特性**
- The relative density (water = 1) is 1.45 (20 ° C), which is higher than the density of water. This means that the same volume of 1% 2C2% 2C3-trichlorobenzene has a larger mass than water. Its density characteristics are related to the relative mass of molecules and the degree of molecular arrangement. 1% 2C2% 2C3-trichlorobenzene molecules contain chlorine atoms, which are relatively large in weight. The arrangement of molecular structures increases the mass per unit volume, resulting in a higher density than water.

For example, when co-heated with an aqueous solution of sodium hydroxide, chlorine atoms can be replaced by hydroxyl groups to form 1,2,3-glycerol. Second, under appropriate conditions, it can also undergo elimination reactions to eliminate hydrogen chloride and form unsaturated bonds. In addition, due to the presence of multiple chlorine atoms in its chemical structure, the substance is relatively stable and not easy to be oxidized or decomposed. However, at high temperatures, light or in the presence of specific catalysts, corresponding chemical reactions also occur.

What are the production methods of 1,2,3-trichlorobenzene?

The first method is based on the halogenation method. First take the appropriate halogenating agent, such as brominating agent and chlorinating agent, so that it should be related to the corresponding alkene substrates. The alkene encounters the halogenating agent, the double bond is opened, and the halogen atom is attached to it, so the embryonic form of the 1%2C2%2C3-%E4%B8%89%E6%B0%AF%E8%8B%AF is obtained. In this process, the choice of the halogenating agent, the temperature and pressure of the reaction, and the properties of the solvent are all important factors. If the halogenating agent is strong, the reaction may be fast, and then the reaction may be increased; the temperature and height can promote the reaction, but it may cause the decomposition of the substance; if the solvent is improper, the reaction rate and the selectivity of the product will be disturbed.
The second method is based on the technique of nucleophil First prepare an aromatic hydrocarbon substrate with a suitable leaving group, and then let the nucleophilic halogen ion attack it. Nucleophilic halogen ions tend to the positive electric center of the substrate, leaving the group to go, and the halogen atom enters to form a 1%2C2%2C3-%E4%B8%89%E6%B0%AF%E8%8B%AF. Among these, the activity of the leaving group, the nucleophilicity of the nucleophilic halogen ion, and the pole of the reaction medium are all key. The activity of the leaving group is high, and the reaction is easy; those with strong nucleophilicity, the substitution speed; if the medium is extremely suitable, the reaction will go forward.
The third method is to find it by the method of metal catalysis. Select the appropriate metal catalyst, such as the complex of metals such as palladium and nickel, so that the aromatic hydrocarbon and the halogen source can react under the catalysis. Metal catalysts can activate the carbon-hydrogen bonds of aromatic hydrocarbons and promote their response to halogen sources. In this process, the activity of metal catalysts, the structure of ligands, and the type of halogen source are all heavy. High-activity catalysts and suitable ligands can improve the efficiency and selectivity of the reaction; different halogen sources have different product distributions.
