1 + -Mercury-3-methylmercury-2-vinyl chloride are all special chemical substances, each with unique physical properties. The following is your detailed description:
Mercury, the only metal that is liquid at room temperature, shines with a silver-white luster, like a flowing moon. Its density is quite high, reaching 13.59 grams/cubic centimeter, just like a heavy treasure hidden in the world. Mercury has an extremely low melting point of -38.87 ° C and a boiling point of only 356.6 ° C. It can evaporate at a lower temperature and quietly pervades the air, like an invisible ghost. Its vapor is colorless and odorless, but highly toxic, and can quietly erode human health.
3-Methylmercury, as an organic mercury compound, is often shown in the form of colorless crystals or oily liquids. It has a faint and special odor, with a density slightly smaller than that of water, about 0.986 g/cm3, which seems light but hidden. The melting point is -43 ° C and the boiling point is 127 ° C. Its volatility is slightly lower than that of mercury, but it should not be underestimated. Because it is difficult to degrade in the environment, it is easily enriched in organisms and transmitted through the food chain, which is extremely harmful to organisms and humans, and can seriously damage the nervous system and cause irreparable damage.
2-vinyl chloride, normally colorless and ether-like odor gas, density is less than air, about 2.15 g/liter, like light smoke floating in the air. Melting point - 153.8 ℃, boiling point - 13.4 ℃, highly volatile, fleeting. Slightly soluble in water, soluble in ethanol, ether and other organic solvents, like a spirit that freely shuttles between different media. Vinyl chloride is flammable, mixed with air to form an explosive mixture, in case of open fire, high heat can cause combustion and explosion, just like a lurking dangerous fire, which may cause disaster at any time.
All three are used in the industrial field due to their unique physical properties, but their toxicity and potential harm should not be underestimated. When using them, care must be taken, and protection and treatment must be taken to avoid endangering life and the environment.

The chemical properties of 1 + -mercury-3-methylmercury-2-chlorobenzene are relatively stable.
Mercury is a highly toxic metal element. It is liquid at room temperature and has volatile properties. In various environmental media, mercury can undergo complex chemical transformations, such as oxidation, reduction, methylation, etc.
3-methylmercury, as an organic mercury compound, is far more toxic than inorganic mercury. In the chemical structure of methylmercury, mercury atoms are connected to methyl groups. This structure enhances its lipid solubility, and it is easier to penetrate biofilms and accumulate and amplify in organisms. In the natural environment, the formation of methylmercury is mainly due to the methylation of inorganic mercury by microorganisms. Its chemical properties are relatively stable under common environmental conditions, and it is not easy to rapidly degrade or transform into other forms.
2-chlorobenzene, as a chlorine-containing aromatic hydrocarbon compound, its benzene ring structure endows it with certain chemical stability. The chlorine atom is connected to the benzene ring. Due to the electronegativity of the chlorine atom, the electron cloud density distribution of the benzene ring changes, which affects its chemical reactivity. However, in general, in general environmental conditions and common chemical reactions, 2-chlorobenzene can maintain a relatively stable structure, and only under specific conditions, such as high temperature, strong oxidants or the presence of specific catalysts, can significant chemical reactions occur, such as substitution reactions However, it should be noted that this stability is relative. Under certain extreme conditions, such as high temperature, high pressure, strong acid bases, or specific microbial enzymes, the chemical properties of these substances will change, causing reactions such as decomposition and transformation.

To prepare 1-aldehyde-3-aldomethyl-2-enaphthalene, there are many methods of synthesis, and each has its own ingenuity, let me come one by one.
First, it can be started from enaphthalene derivatives. First, react with enaphthalene with a suitable reagent and introduce a functional group at a specific position. This step requires fine regulation of the reaction conditions, such as temperature, solvent, and catalyst type and dosage. The reaction proceeds in the desired direction, and a group that can be subsequently converted into aldomethyl is successfully connected. Then, through a specific oxidation reaction, the introduced group is converted into aldomethyl. This oxidation process requires the selection of a suitable oxidizing agent, which not only ensures the efficiency of oxidation, but also does not cause damage to the product due to excessive oxidation. At the same time, at another position, an aldehyde group is introduced through a suitable reaction. This process may involve nucleophilic substitution, addition and other reaction types, and the reaction conditions need to be strictly controlled in order to obtain the target product.
Second, a compound containing aldehyde groups and alkenyl groups can be considered as raw materials. First, the reaction activity of alkenyl groups is used to construct the naphthalene ring structure through addition or cyclization reaction. This construction process requires careful design of the reaction path, taking into account the interaction of each group. After forming the naphthalene ring, the groups in it are modified and converted to generate aldehyde methyl. This step may require a multi-step reaction, and the product needs to be separated and purified after each step to ensure the smooth progress of the next reaction. Finally, after appropriate adjustment and modification, the synthesis of 1-aldehyde-3-aldehyde-methyl-2-enaphthalene can be achieved.
Third, it can also start from compounds with similar structures. Modify and modify its structure, and gradually introduce the desired aldehyde group and aldehyde-methyl group. This strategy requires in-depth understanding of the structural characteristics of the starting compound and clever use of its existing functional groups for reaction. Through rational planning of the reaction sequence, the protection and activation of some groups are carried out first, and then the key reaction steps are carried out to finally achieve the synthesis of the target compound. Each step of the reaction requires rigorous operation, and accurate analysis and identification of the reaction products are carried out to ensure that the synthesis path is correct to obtain pure 1-aldehyde-3-aldehyde-methyl-2-enaphthalene.

1 + -Hg-3-Hg-methyl-2-chlorobenzene should pay attention to the following things during storage and transportation:
Mercury is also highly toxic, its sexual activity, volatile into mercury vapor, inhalation of the human body will harm the nervous system, kidneys, etc. Therefore, when storing and transporting, the first sealing method must keep it out of the air to avoid volatilization. And it is necessary to choose a cool, dry and ventilated place, away from fire and heat sources, to prevent it from leaking due to changes in the environment.
Mercury-methyl, more toxic than mercury, and fat-soluble, easy to accumulate in the body. When storing, it should be stored in a special container, which must be resistant to corrosion and airtight to prevent leakage. During transportation, the escort must be cautious, check its stability, and if there is any abnormal movement, dispose of it quickly.
2-chlorobenzene is also a toxic and harmful product, which is irritating. The storage place should be protected from direct light, because it may stimulate chemical reactions when exposed to light. When transporting, the vehicle should be equipped with protective gear to prevent it from being damaged in bumps.
All three are dangerous chemicals, and strict regulations must be followed for storage and transportation. Personnel need to be professionally trained to explain their hazards and emergency measures. The storage place should be prepared to leak emergency equipment and suitable containment materials. During transportation, in the event of a leak, quickly separate the scene, evacuate the crowd, and handle it properly according to the nature of the object. Do not panic or cause a catastrophe.
