Although the three have different uses, they have significant contributions to the industrial process and life improvement. They are the cornerstone of the chemical industry and promote the development of various industries.

Mercury, lead, and methylmercury are all highly toxic substances, and their physical properties are different. The details are as follows:
Mercury, commonly known as mercury, is the only metal that is liquid at room temperature and pressure. Its color is silver-white, with metallic luster, and excellent fluidity. The density of mercury is quite high, about 13.59 grams/cubic centimeter, which is much denser than common metals such as iron and copper. This property allows mercury to take on a unique form when in liquid state. Its melting point is extremely low, -38.87 ° C, and its boiling point is only 356.6 ° C. It is highly volatile to form mercury vapor. This is one of the major reasons why mercury vapor can invade the human body through the respiratory tract, damaging the nervous system, kidneys and other organs.
Lead is a soft heavy metal. The newly cut mask has a metallic luster, but it is easily oxidized in the air, and a dark gray lead oxide film is formed on the surface. The density of lead is about 11.34 grams per cubic centimeter, the melting point is 327.5 ° C, and the boiling point is 1740 ° C. Lead has good ductility and corrosion resistance, and is often used to make batteries, cable skins, etc. However, after entering the human body, lead will accumulate in bones, liver, kidneys and other organs, causing anemia, nervous system damage and other diseases.
Methylmercury is an organic compound of mercury, which is mostly produced by the action of microorganisms in the environment on mercury. It is a colorless liquid at room temperature and is fat-soluble, which makes it easy to penetrate biofilms and accumulate in organisms. Methylmercury is less volatile than mercury, and has a higher density than water. It is difficult to dissolve in water, but easily soluble in organic solvents. Methylmercury is extremely harmful to the human body, especially on the development of the nervous system. If pregnant women ingest food contaminated with methylmercury, it can cause fetal nervous system development deformities. The famous Minamata disease is caused by long-term consumption of seafood contaminated with methylmercury.

1-% E6% BA% B4, 2-% E6% B0% 9F, 4-%E7%94%B2%E5%9F%BA%E8%8B%AF, these three are all important chemical substances, and their chemical properties are unique.
1-% E6% BA% B4 is a colorless and transparent liquid with a special odor at room temperature and pressure. Its volatility is quite strong, its ignition point is low, and it is very easy to burn. It can react violently with oxygen in the air, and the flame is light blue. Its chemical properties are active and can react with many metals and metal oxides. For example, when it encounters active metal sodium, it can react violently and release hydrogen. Because of its good solubility, it is often used as an organic solvent, which can dissolve many organic compounds, such as oils and resins.
2-% E6% B0% 9F, which is a colorless and odorless gas under normal conditions. The chemical properties are relatively stable, and it is difficult to react with other substances under normal conditions. However, under specific conditions, such as high temperature, high pressure and the presence of catalysts, it can react with hydrogen to form alkanes. Because of its stability, it is often used as a protective gas in industry to prevent certain substances from being oxidized during processing.
4-%E7%94%B2%E5%9F%BA%E8%8B%AF, the appearance is mostly white crystalline powder. Its molecular structure contains specific functional groups, giving it unique chemical properties. It has certain acidity and can neutralize with bases to generate corresponding salts. At the same time, it has a wide range of uses in the field of organic synthesis. It often participates in the synthesis of various complex organic compounds as an important intermediate, and uses its specific functional groups to react with other organic reagents, such as substitution and addition, to construct more complex organic molecular structures.
The difference in the chemical properties of these three stems from the difference in their molecular structure and atomic composition, and these characteristics determine their different uses in industrial production, scientific research, and daily life.

To prepare 1-mercury-2-lead-4-methylarsenic utensils, the methods are as follows:
The first is the method of calcination. The concentrate is selected and crushed into a powder. Put in a crucible and calcine it with charcoal fire. Mercury is volatile, and the top is covered with a condenser, so that the mercury vapor is cold and condensed, and drips into the receiving dish. Lead and methylarsenic minerals, after calcination, either form a metallic state or are easily soluble compounds, which are convenient for subsequent separation.
The second is the method of leaching. The ore is broken into pieces and thrown into a specific solvent. For example, acid solution can dissolve lead and methyl arsenic related compounds, while mercury or mercury-forming salts dissolve. After full stirring and soaking, the active ingredients are fully incorporated into the solution. After filtering, the residue is removed to obtain a clear solution containing mercury, lead, and methyl arsenic.
Another method is precipitation. Add an appropriate precipitant to the obtained clear solution. If you want to get mercury, you can add sulfide. Mercury forms mercury sulfide precipitation, which is black and heavy and easy to separate. To get lead, add sulfate, and lead forms a white precipitate of lead sulfate. Methyl arsenic can also be precipitated by specific reagents. After precipitation, it is washed and dried to obtain pure mercury, lead, and methyl arsenic compounds.
There is also an electrolysis method. The salt solution containing mercury, lead, and methyl arsenic is placed in an electrolyzer. Using graphite or metal as an electrode, an electric current is passed. Mercury ions and lead ions get electrons at the cathode, and mercury and lead metals are precipitated respectively. The ions of methyl arsenic may also undergo redox reactions at the electrode, and the corresponding products can be generated according to specific conditions. After purification, pure methyl arsenic-related substances can be obtained.
This method can make 1-mercury-2-lead-4-methyl arsenic utensils, but each method has its own advantages and disadvantages, and it must be used according to the actual situation.

Mercury, oil, and methylmercury are all kinds of precautions during storage and transportation, which are related to human life and the environment, and must not be ignored.
Mercury is a highly toxic substance that can evaporate at room temperature, forming mercury vapor, which enters the lungs and hurts the brain and nerves. When storing mercury, use a sturdy device and seal it tightly to prevent leakage. The device should be placed in a cool and cool place to avoid heat and light, because heat and light can promote the volatilization of mercury. During transportation, the package must be tight, with warning signs, and a safe transportation method to protect the safety of the escort.
Oil is flammable and pollutes the environment. When storing, choose a place away from fire and heat sources to prevent fires. Oil tanks need to be sturdy and non-destructive to prevent leakage. If oil leaks into the ground, seeps into the soil, pollutes the soil and water sources, there will be endless problems. When transporting oil, choose a professional oil tanker truck and regularly check the car's seal and safety devices. During driving, avoid densely populated and high-risk areas, drive cautiously to prevent accidents and oil leakage.
Methylmercury is more toxic than mercury, and is mostly caused by industrial pollution. Storage of methylmercury, under strict conditions, use special containers to keep it low temperature, dry and protected from light. Containers need to be resistant to corrosion, because methylmercury is highly corrosive. Transportation of methylmercury, escorted by special personnel, monitored throughout the process. The means of transportation are thoroughly disinfected to prevent residual methylmercury from contaminating other materials.
All three are dangerous. When storing and transporting, from personnel training to equipment maintenance, from packaging specifications to emergency plans, all need to be thorough. A little sparse risk will harm the ecology and endanger the well-being of the people. Therefore, those who do this should be in awe, abide by strict regulations, and ensure all things go smoothly and the environment is peaceful.
