chloroacetylpyridine

It is also bitter, which is the mother liquor left over from seawater production. Its main use is wide, and it is important for industrial, industrial and food fields.
First of all, in the food industry, it is often used as a solidification method for tofu. To make tofu in the method of making tofu, it is necessary to add oil to the bean, so that the protein in the bean can be agglomerated and form tofu. This is because the seeds and seeds in the bean can interact with the protein of the bean, promoting the aggregation of protein molecules and the formation of tofu. This product is made of tofu, which has a good taste, a good taste, and a special taste.
Secondly, in the chemical industry, it is the key to extract many important raw materials. Chloride, sulfuric acid, bromide, etc. can be extracted from the oil. Chloride is widely used in the manufacture of refractory materials, gold and chemical fertilizers; sulfuric acid can be used in the production of oil, printing and dyeing aids, etc.; bromide plays an indispensable role in the field of oil, oil, photographic materials, etc.
Furthermore, in the field of oil, oil also has its uses. For example, some of the ingredients in the oil can be used in the production of oil. For example, the chemical compounds in it can be used as a treatment, solution, etc., and have certain effects on the treatment of certain diseases.
In addition, in the field, oil can be used in oil. Because it has a certain density, when the seeds are placed in the solution, the density can be different according to the degree and density of the seeds, so that the seeds sink, do not float, and produce good seeds, and improve the amount of crops.
Of course, it seems ordinary, but it has many uses, and it is important for many lines of crops.

Mercury acetamide is a highly toxic thing, and its synthesis method is forbidden and must not be done. However, in ancient books, there are occasional relevant records. Although it has been strictly prohibited today, and it is extremely harmful, I can still briefly describe one or two methods of the past for you. Just because you know it, you must not try it.
In ancient times, mercury and acetamide were co-placed in a closed danding, accompanied by various methods of heat. First, slow down the fire, so that the mercury gradually melts, like flowing silver. Acetamide also gradually melts in heat, and the two blend. Then the fire is fierce, and the heat in the tripod evaporates. However, this process is extremely dangerous, and the poison of mercury is very easy to escape. If you are not careful, it will cause disaster.
Another method is to take mercury and dissolve it in a specific concoction, such as a sulfur-containing medicine, to form a mercury salt. Then mix it with acetamide in a delicate ratio, put it in a special pottery dish, bury it three feet underground, and nourish it with the warmth of the earth's atmosphere. After several days or even months, mercury acetamide may be obtained. However, this method also needs to be extremely cautious. If there is a slight mistake, it will not only fail to synthesize, but will cause highly toxic overflow and harm lives.
Today, mercury acetamide has been banned because of its severe toxicity, which is a disaster to humans, animals and the environment. The methods recorded in the past are only for academic inquiry and must not be put into practice. We should abide by the law, protect the environment, and ensure the well-being of all people.

Mercury, whose chemical symbol is Hg, is liquid at room temperature, and is the only liquid metal. Its physical properties are unique and quite wonderful.
Mercury has a silver-white color and a metallic luster, just like the moon, shining brightly. Its texture is soft, although it is liquid, it can flow freely, like a smart silver snake, winding and winding. And the density of mercury is very high, reaching 13.59 grams/cubic centimeter. Compared with common liquids, it weighs several times more, so it is placed in a container and is as stable as a rock.
Furthermore, the melting point of mercury is extremely low, -38.87 ° C, which is difficult to solidify in ordinary low temperature environments; and the boiling point is not very high, 356.6 ° C. This property allows mercury to remain in a liquid state within a specific temperature range, making it widely used.
Mercury has a high surface tension, and droplets on a flat surface often aggregate into beads, which are like mercury falling on the ground, round and full, and not easy to disperse. This property is derived from the interaction force between mercury atoms, which makes its liquid surface seem to be covered with an elastic film.
In addition, mercury has good electrical conductivity. Although it is slightly inferior to some common metals, its electrical conductivity is also excellent in liquid substances. Therefore, in some special electrical devices, mercury can also play an important role.
Although mercury has many unique physical properties, it is also toxic. Mercury vapor and mercury compounds can penetrate the human body through the respiratory tract, digestive tract, and skin, causing damage to the nervous system, kidneys, and other organs. Therefore, when using and disposing of mercury, extreme caution and scientific norms should be followed to prevent the harm of mercury poisoning.

Mercury, in the process of storage, should pay attention to all kinds of things.
First and hidden. Mercury has a special nature, and it must be used to make things dry, and it is easy to be invaded by water vapor, causing its nature. If it is high in the earth, it may also be caused to be reversed. And the place where it is hidden, it is isolated from acids, water and other substances. The nature of acid is strong, and when it encounters mercury, it is feared that it will cause severe reactions and cause danger. Furthermore, it is used to keep it secret to prevent it from escaping, and to avoid the interaction of its components in the air.
Second words. When it comes to mercury, it is necessary to use high-quality equipment, and the equipment is fixed to prevent its leakage. It is best to travel in a safe place, to avoid severe earthquakes and bumps, to avoid mercury earthquakes, or to cause disruption in the region, to damage its products, or even to cause danger. The people who are in trouble will be affected by it, and their nature will be endangered, and they will know how to deal with it urgently. And on the way, they should control the environment and keep things dry and difficult. If it is a high-level place, there are measures to reduce it; if it rains, they should not be protected from water.
In this way, mercury should be stored in the environment, and attention should be paid to the dry environment, barriers, secret equipment, and the control of the environment, so as to protect its performance and avoid the life of danger.

Haiyu is a beautiful place, and its hidden safety risks are very serious. The land of Haiyu is located on the shore of the sea, and the wind and waves are fickle. The first to bear the brunt is the risk of flood. In summer and autumn, hurricanes occur frequently, and huge waves are monstrous. If the embankment is slightly not solid, it will cause seawater to pour back and flood the farmland, endangering both humans and animals.
Furthermore, Haiyu is often a traffic hub, and ships come and go like a weave. However, the maritime weather changes rapidly, the reefs are hidden under the water, and the fog pervades the sea surface. Ships may lose their course or be damaged due to hitting the reef, resulting in the collapse of goods and the death of personnel. This shipping risk is also.
And Haiyu has a lot of fishing, and fishermen often go to sea to work. In the deep sea, the environment is unpredictable, or in case of strong convective weather, sudden winds and rainstorms, the boat cannot resist its strength; or in case of fierce marine creatures, it will hurt people and kill them. And rescue at sea is not easy, once in danger, it is difficult to get help in time, and this fishery is also in danger.
And the land of Haiyu, because it is close to the border, there is a risk of foreign enemies watching. In the past, there were bandits invading the border, looting property, and disturbing people's lives. Although there are barriers and soldiers stationed bravely, but traitors can take advantage of the gap, endangering the peace of the people and the stability of the society.
In addition, the people of Haiyu mostly depend on the sea for their livelihood and rely heavily on marine resources. If overfishing results in the depletion of fishery resources; or industrial emissions, oil spills at sea, etc., deface the marine ecology, all of which will ruin people's livelihood and lead to disasters. The risk of ecological damage cannot be ignored.
To sum up, the safety risks of floods, shipping, fishing, border problems, and ecology in a good place in the ocean cannot be ignored. We should take precautions in the future to ensure the peace of the sea and the people's livelihood.
