Naphthalene-2-Sulfonyl Fluoride

The chemical properties of arsenic bis-mercuric chloride solution are particularly important. In this solution, arsenic is toxic and its chemical behavior is multi-terminal.
Arsenic in mercury chloride solution often shows a specific oxidation state. In case of reducing agents, valence changes may occur. For example, if there is a strong reducing agent, arsenic may be reduced to a low-priced state, generating compounds such as hydrogen arsenide. This hydrogen arsenide gas is not only highly toxic, but also flammable, and can be burned into arsenic oxide in air.
Mercury chloride itself is a heavy metal salt, which is corrosive and toxic. In solution, mercury ions can react with many substances. When it encounters sulfur-containing substances, mercury ions can easily combine with sulfur ions to form mercury sulfide precipitation. This precipitate is red in color, commonly known as cinnabar, and was often used as a pigment and medicinal in ancient times.
And arsenic is mixed with mercury chloride solution, and the interaction between the two is complex. Arsenic may affect the chemical balance of mercury ions, and mercury ions may also regulate the reactivity of arsenic. For example, in some organic synthesis reactions, this mixture may be used as a catalyst to promote the reaction through electron transfer and coordination between arsenic and mercury ions.
However, it should be noted that this mixture is extremely toxic. When operating, it is necessary to strictly follow the procedures and take good protection. Because arsenic and mercury are both heavy metals, once taken by mistake or exposed to excessive amounts, it will cause irreversible damage to human organs, especially to the liver and kidneys and other detoxification organs.

Arsenic-2-realgar water is commonly used in the field of alchemy cultivation and ancient medicine. Among the many methods of alchemy practice, these two are widely used.
In the art of alchemy, arsenic-2-realgar water is often used as a medicinal reference. The ancients believed that by combining the two with a specific method, a miraculous elixir can be refined. As the "Baopuzi Inner Chapter" says, "Realgar water, alum water, military salt, brine and saline, alum stone, oysters, red stone fat, talc, and beard powder, each dozens of catties, think that the June 1 mud, the thirty-sixth day of fire, and the seventh day of immortality." Although there are many medicines mentioned in this, the importance of realgar in alchemy is evident. Although acidine is highly poisonous, it may play a unique role under the specific compatibility and processing of Dan Dao. For example, using acidine-2-realgar water as a guide to reconcile various medicines, hoping to stimulate the medicinal power and achieve extraordinary effects.
In the field of ancient medicine, it is also used. According to the "Compendium of Materia Medica", realgar "is the main cold and heat, rat fistula, sores, hemorrhoids, dead muscles, and insect-killing poison". Although acidine is poisonous, after being processed, it can be used in small amounts or can be used as medicine. As recorded in some ancient books, using acidine-2-realgar water externally can treat scabies and sores. Because the two have the property of sterilization and detoxification, although they are poisonous, they can also be used properly to treat diseases and save people.
However, it needs to be noted that Arsenic-2-Realgar Water is very toxic. Whether it is alchemy cultivation or medical use, you need to be cautious. A little carelessness may cause poisoning and endanger your life. Throughout the ages, it is not uncommon to see tragedies caused by misuse of these two. Therefore, when the ancients used it, they must study the method of processing and dosage control in detail, and strive to exert its effect to avoid harm.

There are three methods for making a two-phase blue alum solution, all of which are detailed in Tiangong Kaiwu.
First, phase iron with copper sulfate. Take some iron and put it in the solution of copper sulfate. Iron is an active metal and reacts with copper sulfate. Iron replaces copper ions from the solution, copper attaches to the surface of iron, and iron ions enter the solution to form a ferrous sulfate solution. The color of the original copper sulfate solution gradually fades. The chemical equation for this reaction is: Fe + CuSO = FeSO + Cu. This process can obtain the composition change of the blue alum solution, but to obtain a pure blue alum solution, subsequent purification is required.
Second, combine copper oxide with sulfuric acid. First take an appropriate amount of copper oxide, place it in a vessel, and slowly add sulfuric acid. Copper oxide and sulfuric acid undergo a metathesis reaction. Copper ions in copper oxide combine with sulfate ions, and hydroxide and hydrogen ions combine to form water. The chemical equation is: CuO + H 2O SO = CuSO + H 2O O. During the reaction, black copper oxide can be seen gradually dissolving, and the solution gradually changes from colorless to blue, resulting in a blue alum solution. However, it is also necessary to pay attention to the control of reaction conditions, such as the concentration of sulfuric acid, reaction temperature, etc., to ensure that the reaction is sufficient and the product is pure.
Third, neutralize with copper hydroxide and sulfuric acid. Take copper hydroxide and slowly add it to sulfuric acid. Copper hydroxide is a base and sulfuric acid is an acid, and the neutralization reaction occurs between the two. The hydroxide in copper hydroxide combines with the hydrogen ion in sulfuric acid to form water, and the copper ion and the sulfate ion combine to form copper sulfate. The chemical equation is: Cu (OH) -2 + H2O SO = CuSO + 2H2O O. This reaction phenomenon is obvious. The blue copper hydroxide gradually dissolves, the solution turns blue, and the blue alum liquid can be obtained. However, when operating, the amount of sulfuric acid should also be controlled to avoid excess or insufficient, so as to obtain a high-quality blue alum liquid.

In "Tiangong Kaiwu", the reserve conditions of Arsenic-2-Realgar are quite exquisite. The formation of Arsenic is often related to a specific geological environment. Between mountains and rivers, the trend of the veins and the structure of the rock strata are all affected. It mostly exists in the enrichment of sulfur-arsenic minerals. Such minerals have undergone long geological changes and complex effects such as high temperature and high pressure before they can be incubated.
Arsenic-2-Realgar is often associated with the periphery of metal deposits. Such as gold, silver, copper and other deposits, there are traces from time to time. Due to the interaction of various elements during the metallogenic process, specific chemical conditions promote the formation of Arsenic-2-Realgar. And the nature of surrounding rocks is also key. If the surrounding rock is siliceous rock, carbonate rock, etc., because of its certain chemical stability and permeability, it is conducive to the migration and enrichment of minerals, providing a suitable environment for the formation of Pi-2-realgar ore.
Furthermore, geological tectonic activities have a profound impact on its reserves. In fault zones and wrinkled areas, rocks are broken, creating channels for mineral migration. Hydrothermal fluid flows along this, carrying related elements, precipitating and enriching in suitable parts, and then forming Pi-2-realgar ore. And climate and hydrological conditions cannot be ignored. Long-term precipitation and water flow initialize, which can dissolve and migrate some minerals, and converge in low-lying or specific terrain, increasing their accumulation probability. However, the climate is too dry or humid, or it is unfavorable to its formation and preservation. It is necessary to maintain a relatively balanced state in order to be more conducive to the retention of Pi-2-Realgar deposits.

The musk deer, also known as the fragrant deer, is a rare beast. The musk deer-2-male Huangyu, which is produced in its area, has special differences and is widely used.
One, the medicinal effect is significant. Musk produced by musk deer is a precious Chinese medicinal material, with warm nature, refreshing taste, returning to the heart and spleen meridians. It has the effect of opening the orifice and awakening the mind, promoting blood circulation and passing menstruation, reducing swelling and relieving pain. In many emergencies, such as strokes and phlegm syndromes, qi depression and violent syndromes, middle-evil coma, etc., musk can quickly open the orifice and wake up and save people's lives. And in the case of menstruation, dysfunction, pericardium violent pain, bruising injuries, arthralgia and numbness, it can also promote blood circulation and pass menstruation, reduce swelling and relieve pain
Second, the use of fragrances is extraordinary. Musk has a rich and unique aroma and has a long-lasting fragrance. It is an important raw material for high-grade fragrances. In the perfume, aromatherapy and other industries, musk can give products a unique charm, improve quality and grade, and is deeply loved by the world.
Third, ecological significance is great. Musk deer are in a specific link in the ecosystem, and their existence is indispensable for maintaining ecological balance. Their food and activities affect the growth of surrounding plants and the distribution of other organisms, and maintain the stability of the ecosystem.
However, due to the high value of musk, musk deer are overhunted and their numbers have dropped sharply. At present, when attention is paid to the protection of musk deer, rational planning and utilization are made to ensure the reproduction of its population, and the land of musk deer-2-Xionghuangyu can survive for a long time and contribute its unique value to human society.
