    What are the physical properties of 1,2-dibromo-3-iodine-5-methylbenzene?
    Today's questioner said: "What are the physical properties of 1% 2C2-dihydroxy-3-medicine-5-methylbenzene?" I will answer in the style of "Tiangong Kaiwu".
    Methylbenzene is a genus of organic compounds. Its shape, at room temperature, is mostly a colorless and transparent liquid, like clear dew, with a clear texture. Under visible light, there is no disturbance of variegated colors.
    Its taste has a special aroma, but this fragrance is not pleasant and rich. If you smell it, you can feel that its breath is unique. If you smell it for a long time, it may cause discomfort, because its breath is slightly toxic.
    In terms of its density, it is lighter than water. If water and methyl benzene are placed in the same place, methyl benzene will float on water, just like oil floating on water, and the boundary is clear.
    Its boiling point is between hundreds of degrees. When heated to a specific temperature, it turns into a gaseous state and rises. The melting point is lower, and under normal cold temperatures, it can still maintain a liquid state.
    Furthermore, methyl benzene can be miscible with many organic solvents, such as alcohols, ethers, etc. When mixed, it is seamless and not separated. However, it is difficult to blend with water. The two meet, live in one place, and separate themselves.
    This is the general physical properties of methyl benzene. Although it is difficult to provide details, I hope it can solve your confusion.
    What are the chemical properties of 1,2-dibromo-3-iodine-5-methylbenzene?
    Methylmercury is a compound that combines mercury and methyl. Its chemical properties are unique and have the following characteristics.
    Methylmercury is highly volatile. At room temperature, it is easily volatilized from liquid to gaseous state. This characteristic makes it easy to escape into the atmosphere, widely dispersed in the environment, and the scope of pollution is gradually expanding.
    It is lipid-soluble. Compared with water-soluble substances, methylmercury is more soluble in lipids. The cell membranes of organisms contain more lipid components, so methylmercury can easily penetrate the cell membranes and then accumulate in organisms. This property makes it difficult for methylmercury to be excreted from organisms. With the transmission of the food chain, the concentration gradually increases, eventually leading to a large amount of methylmercury accumulation in high trophic level organisms, posing a serious threat to biological and even human health.
    Methylmercury has relatively stable chemical properties. Under common environmental conditions, it is not easy to decompose or undergo chemical reactions. This stability makes methylmercury retain for a long time once it enters the environment, causing continuous harm to the ecosystem. It can go through a long time without degradation in environmental media such as water and soil, accumulating continuously, further exacerbating the degree of pollution.
    Furthermore, methylmercury is neurotoxic. Its damage to the biological nervous system is particularly significant. Once in the human body, it can accumulate in the brain tissue through the blood-brain barrier, interfering with the normal function and signaling of nerve cells. Long-term exposure or ingestion of methylmercury-containing substances can cause neurological symptoms such as numbness, tremor, vision and hearing impairment, and even life-threatening in severe cases.

    What are the synthesis methods of 1,2-dibromo-3-iodine-5-methylbenzene?
    To make acetylaniline, there are various methods. First, it can be obtained by co-heating aniline and glacial acetic acid. Take an appropriate amount of aniline and glacial acetic acid in a round bottom flask, add a little zinc powder to prevent the oxidation of aniline, then install a reflux device, and slowly heat and reflux for several hours. After the reaction is completed, pour the reaction solution into cold water, and acetylaniline crystals will precipitate. After suction filtration, washing, and drying, a pure product can be obtained. This is a commonly used method and the operation is relatively simple.
    Second, acetic anhydride reacts with aniline instead of glacial acetic acid. In a conical bottle, first dissolve aniline in an appropriate amount of organic solvent such as ether, and then slowly add acetic anhydride dropwise. When adding dropwise, stir and control the temperature to avoid excessive reaction. After dropping, continue to stir for a period of time to promote the complete reaction. After that, add water to precipitate the product, and after separation and purification steps, acetylaniline can also be obtained. This method has a fast reaction rate and a high yield.
    Third, acetyl chloride is prepared by reacting with aniline. Due to the high activity of acetyl chloride, the reaction is violent, and it needs to be carried out at low temperature and in the presence of an acid binding agent. Aniline is mixed with an acid binding agent such as pyridine in a low temperature environment, and acetyl chloride is slowly added dropwise, and the reaction occurs rapidly. After the reaction is completed, acetylaniline products can also be obtained through subsequent treatments such as extraction, distillation, and recrystallization. However, this method needs to be operated with extreme caution due to the active nature of acetyl chloride.
    What are the precautions for storing and transporting 1,2-dibromo-3-iodine-5-methylbenzene?
    When storing and transporting acetylene with one carbon and two hydrogens, chloroform with trichloride, and pentane with five carbons, many matters must be paid attention to.
    Acetylene is very active, flammable and explosive. When storing, it should be placed in a cool and well-ventilated place, away from fire and heat sources. Because it can form an explosive mixture when mixed with air, it can cause combustion and explosion in case of open flame and high heat, so the electrical equipment of the warehouse must be explosion-proof, and fireworks are strictly prohibited. When transporting, it is also necessary to ensure that the container does not leak, collapse, fall, or damage, and the speed should not be too fast. Do not forcibly overtake to prevent vibration and impact from causing danger.
    Chloroform, has a special odor. Although it is not flammable, its vapor and air can form an explosive mixture. When storing, it should be sealed and stored in a cool place away from light, because light can promote its decomposition to produce toxic phosgene. During transportation, it is necessary to prevent damage to packaging and containers, and avoid mixed transportation with oxidants, active metal powders, etc., because it will react violently with it.
    Pentane, extremely flammable, its vapor is heavier than air, and can spread at a lower place to a considerable distance. In case of fire, it will catch fire and backfire. Storage should be in a low temperature, ventilated warehouse, and the warehouse temperature should not exceed 30 ° C. When transporting, it is also necessary to keep away from fire and heat sources. In summer, it should be transported in the morning and evening to prevent sunlight exposure. The exhaust pipe of the vehicle must have a fire-blocking device.
    These items are all related to safety during storage and transportation. If you are not careful, you will cause disasters. Therefore, the precautions in all aspects should not be ignored.
