The product is 2-mercury-1,3-diene-5-allyl, which is an organic mercury compound. Mercury, known as "mercury", is the only metal element that is liquid at room temperature and pressure. And allyl is an organic group with unsaturated bonds.
This type of organic mercury compound has unique properties. Its chemical activity is high, due to the interaction between mercury atoms and allyl. The unsaturated bond on the allyl gives it the ability to participate in a variety of addition reactions, and can react with many electrophilic reagents to generate novel organic compounds.
However, mercury has certain toxicity. Organic mercury compounds are often more toxic than inorganic mercury. Because they are more likely to penetrate biofilms and accumulate in organisms, they can cause serious damage to the nervous system, immune system and many other physiological systems of organisms.
In chemical reactions, the stability of mercury-carbon bonds in this compound is different, and it can break under specific conditions, which can lead to a series of chemical reactions, or participate in the process of organic synthesis to build new carbon-carbon bonds and carbon-hetero bonds. However, due to its toxicity, in practical applications, extreme caution is required to strictly control its usage and emissions to prevent irreparable harm to the environment and organisms.

Mercury is also a highly toxic thing. Its primary and tertiary states are rare, while divalent mercury is always present in the world. The uses of mercury were quite extensive in the past.
The ancients have long been involved in the burning and refining of Dan Sand. In Dan Sand, mercury sulfide is also mercury, which can be separated by burning and refining, which is the importance of ancient alchemists. If you want the recipe for longevity, you can refine the alchemy, and mercury is the key thing. For example, in Ge Hong's "Baopuzi", there are many alchemy words, and mercury is indispensable in it.
Furthermore, mercury is used in medicine, and there are traces to follow. Ancient physicians knew that mercury has the ability to disinfect and sterilize. External use can treat scabies and evil sores. However, the toxicity of mercury is severe, and it needs to be taken with caution. If there is a slight mistake, it will cause a big disaster. Therefore, although mercury is used as medicine, it is mostly used externally.
And in the process of production, mercury also develops its strengths. The ancient gilting technique borrows the characteristics of mercury. The gold and mercury are fused into gold amalgam, which is applied to the surface of the utensils, heated to evaporate the mercury, and the gold remains on it, and the utensils are golden. This technique is used to decorate utensils, making them beautiful and abnormal.
However, the toxicity of mercury cannot be prevented. Its poison is easy to invade the human body, damage the internal organs of people, and confuse people's minds. Therefore, when using mercury, be aware of its benefits and weigh it carefully. Although it has many uses, it should not be forgotten because of its use. It is necessary to treat it with caution.

To make 2 catties of mercury, 2 catties of dicarbonum, and 2 catties of river sand, the method is as follows:
Prepare a good device first, preferably a copper kettle, which is clean and scale-free, before it can be used together. Take Dan sand, choose its color red and pure, and study it as a fine powder. The finer the better, and put it aside for later use.
Take an appropriate amount of mercury on the scale. The mercury should be pure and free of impurities, and pour it into the kettle. Slowly pour the ground Dan sand into the kettle containing mercury, and gently stir with a wooden pestle to make sure the two are evenly mixed.
Then scale and take the dialum, which must also be of high quality. Smash it, grind it into powder, slowly add it to the kettle, and then stir it to make it fully blend with the mixture of mercury and Dan sand.
After that, take the river sand, wash it, remove mud impurities, drain the water, and add it to the kettle according to the amount. Stir again to make all things seamless.
Seal the kettle, and apply yellow mud to the gaps to ensure that there is no leakage at all. Place the kettle on the stove and simmer slowly. The heat is extremely critical, and it should not be too fierce or too slow. At the beginning, the fire should be small, and heat slowly to make the contents of the kettle gradually warm. After a while, the fire can be slightly increased, but it still needs to be mild.
This continuous heating, after several hours, requires special personnel to guard the period, and cannot be slack a little. At a certain moment, changes can be seen in the kettle. When the reaction is complete, turn off the flame, and wait for the kettle to cool naturally.
After cooling, carefully open the lid of the kettle, and the contents, which are the required mercury, dialum, and river sand products, can be obtained according to the corresponding amount, carefully collected for other uses.

Nowadays, carbon monoxide, carbon dioxide, acetylene, etc., are important for storage, and need to be paid attention to.

Those who are not flammable, their ignition is very low, and the explosion limit is not limited. In the place of storage, it must be connected to the best place, and the source of ignition, fire, and all possible sources of sparks. The storage containers used must be those with good tightness and resistance to prevent leakage. On the way, also be careful to avoid strong shock, causing the container to be damaged.
Carbon monoxide, toxic to the point of toxicity, color and smell, can be detected. In the place of storage, it is necessary to have perfect communication and equipment to detect leakage. The container should be sealed to prevent carbon monoxide from escaping. In case of leakage, special attention should also be paid. Once it leaks, the crowd should be evacuated immediately, and it must not be slightly damaged.
Carbon dioxide is flammable and toxic, but at high temperatures, it can cause asphyxiation. If it is not stored, it should be kept in good condition. The storage container needs to be able to withstand a certain force, because carbon dioxide is often stored in liquid, and the force is large. In the container, it is necessary to prevent the container from being hit and affected, so as not to increase the force.
Acetylene is flammable and explosive, and its chemical properties are not active. If it is stored, it cannot be oxidized and co-stored, and it is necessary to avoid fire and gas sources. The container used needs to be filled with special porous materials, and acetone is injected to dissolve the acetylene in it. Therefore, be careful to move the container to avoid falling or colliding, so as to prevent the acetylene from being released and becoming dangerous.

Mercury is a highly toxic substance. Its monovalent mercury and trivalent mercury are both toxic, and divalent mercury cannot be ignored. Mercury and its compounds are extremely harmful to the environment.
In the natural environment, mercury can be transported and transformed through various routes. It can evaporate from the soil to the atmosphere and return to the ground with precipitation. In water bodies, mercury will combine with the substances in the water, or settle in the bottom of the water, or be ingested by aquatic organisms. After aquatic organisms accumulate mercury, it is transferred through the food chain and eventually to humans.
Mercury is extremely harmful to human health. It can invade the human body through the respiratory tract, digestive tract and skin. After mercury enters the human body, it is easy to accumulate in the brain, kidneys and other organs. Long-term exposure to mercury can damage the nervous system, causing tremors, insomnia, memory loss and other symptoms in the human body, and even mental disorders. It also damages the kidneys, or causes abnormal renal function. If pregnant women are exposed to mercury, mercury can pass through the placenta, affecting the development of the fetus, causing fetal malformation or mental retardation.
The harm of mercury to the environment and human health cannot be taken lightly. Therefore, the use and emission of mercury should be strictly controlled, and monitoring should be strengthened to reduce its threat to the environment and human health, and protect the natural ecology and people's well-being.
