What are the physical properties of Trichlorobenzene 1,2,4-?
1,2,4-Trichlorobenzene is one of the organic compounds. Its physical properties are as follows:
From the perspective of normal temperature, it is a colorless liquid with a special smell and a pungent smell. Its boiling point is quite high, about 213 ° C. Due to the intermolecular force, it takes more energy to change it from liquid to gaseous. The melting point is also not low, about -17 ° C, indicating that it solidifies at relatively low temperatures.
When it comes to solubility, it is difficult to dissolve in water because it is a non-polar molecule, while water is a polar molecule. According to the principle of "similar miscibility", the two are difficult to dissolve. However, it has good solubility in organic solvents such as ethanol, ether, benzene, etc. Because organic solvents are mostly non-polar or weakly polar, they are similar to the polarity of 1,2,4-trichlorobenzene molecules.
1,2,4-trichlorobenzene has a higher density than water, about 1.45g/cm ³, so if mixed with water, it will sink to the bottom of the water. Its volatility is relatively low, and it evaporates slowly at room temperature and pressure. This property also affects its distribution and migration in the environment. In addition, it has a certain refractive index, and when light passes through, the direction will change in a specific way, which is one of its optical properties.

Trichlorobenzene 1,2,4 - What is the impact on the environment?
1,2,4-Trichlorobenzene has various effects on the environment. It is toxic and can cause pollution. If dispersed in the atmosphere, it can persist for a long time and migrate with the wind, causing a wide area of influence. It falls into the soil or seeps into groundwater, causing soil to lose fertility, water to become polluted, hindering plant growth, and causing plant dysplasia and yield loss. And it is fat-soluble, easy to accumulate in organisms, accumulate along the food chain, and damage biological health. In animals, it may cause diseases in the reproductive, immune, and nervous systems, harming their reproduction and survival. In humans, if it is infected through breathing, diet, or skin contact, or causes liver and kidney damage, increasing the risk of cancer.

Due to the lack of reaction materials, different levels of chlorination can be generated. It needs to be precisely controlled in order to improve the yield of 1,2,4-trichlorobenzene. The yield of reaction materials and the rate of chlorine penetration are all factors. High yield may cause the formation of polychlorinated compounds; if the rate is not high, it will also affect the performance of the reaction.
Second, it can be synthesized from other chlorobenzene derivatives. For example, some dichlorobenzene, under specific conditions, can generate 1,2,4-trichlorobenzene in one step. In this way, the properties of the initial dichlorobenzene need to be determined, and the reverse parts of the compound need to be synthesized. The difference is due to the difference of the molecules, and the reaction activity and reaction position are different. In order to make the reaction move in the direction of generating 1,2,4-trichlorobenzene, it is necessary to refine the catalysis and the reaction medium.
Furthermore, there are also aromatic derivatives starting with a series of reactions, introducing chlorine atoms and molecules of 1,2,4-trichlorobenzene. This method may involve multi-step synthesis of anti-compounds, including substitution of anti-molecules, rearrangement of anti-molecules, etc. Each step needs to be controlled to ensure maximum production of high-grade 1,2,4-trichlorobenzene.
For the production of 1,2,4-trichlorobenzene, it is necessary to consider factors such as the availability of raw materials, cost considerations, and product quantity requirements.

Operators must wear appropriate protective equipment, such as gas masks, chemical protective clothing, etc., to ensure their own safety.
Third, when transporting, transportation vehicles and containers that are compliant should be selected. Transportation vehicles need to be equipped with corresponding emergency treatment equipment and protective equipment for emergencies. During transportation, ensure that the vehicle runs smoothly, avoid bumps and vibrations, and prevent package damage. At the same time, the transportation route should try to avoid densely populated areas and water sources to reduce the harm caused by leakage in the event of leakage.
Fourth, the storage place should be set up with obvious warning signs to inform others that it is toxic and harmful substances, and irrelevant personnel are strictly prohibited from approaching. And the storage environment and containers need to be inspected regularly to check whether there are leaks, deterioration, etc. If there is any abnormality, effective measures should be taken immediately to deal with it.
First, this material is toxic and harmful to humans and animals. When storing, it is necessary to choose a cool, dry and ventilated warehouse, and it should be stored in isolation from oxidants, acids, alkalis, etc., and must not be mixed in storage to avoid dangerous chemical reactions. The temperature of the warehouse should also be strictly controlled and should not be too high to prevent it from changing its properties due to temperature changes and increasing the risk factor.
Second, when handling, the operator must handle it with care to avoid damage to the container. Because of its volatility and toxicity, if the container is damaged and leaks, it will not only pollute the environment, but also endanger the health of the surrounding people.
