Dibenzothiazole Disulfide

Arsenic disulfide, or realgar, has many main uses. In medicine, realgar has the effect of detoxification and insecticide, dryness and dampness to remove phlegm, and malaria. The "Shennong Materia Medica Classic" lists it as a middle grade, saying that it is "the main cold and heat, rat fistula, acne, raging hemorrhoids, dead muscle, and poisonous to kill 100 insects." Throughout the ages, doctors have often used it to treat scabies, carbuncle, snakeworm bites and other diseases. External use can be ground and sprinkled or adjusted, and internal use should be as described in the "Introduction to Medicine". However, it is poisonous, and internal use must be cautious.
In the process of alchemy, realgar is also quite important. In ancient alchemy, alchemists regarded it as an important raw material, hoping to refine miraculous pills with its characteristics. For example, Ge Hong's "Baopuzi Inner Part" has a relevant account. During the process of alchemy, realgar undergoes complex chemical reactions, or becomes something else. Although this contains mostly imaginary ingredients, it reflects the ancients' exploration of material changes.
In the field of folk customs, realgar has unique uses. During the Dragon Boat Festival, there are folk customs such as drinking realgar wine and applying realgar to children's foreheads. This comes from traditional cognition, believing that realgar can ward off evil spirits and avoid epidemics. For example, in "The Legend of the White Snake", the white lady drinks realgar wine in its original form. Although it is a legend, it proves the status of realgar wine in folk culture. People use it to apply it to children's foreheads to become the word "king", which means to borrow the power of realgar to protect children's health.
In industry, realgar also contributed. Although the ancient industry was not as developed as it is today, realgar contains arsenic and can be used as a raw material for the extraction of arsenic and arsenide. Based on this, modern industry has developed a variety of arsenic-related industries, which play an important role in metallurgy, chemical industry and other fields. This can also see the expansion of the use of realgar with the evolution of the times.

Arsenic disulfide, or realgar, is a traditional mineral medicine. It has been recorded in many ancient books. Its physical properties are unique. Let me tell you in detail.
The color of realgar is orange-red, distinct and unique, and it is eye-catching. Its texture is brittle and fragile, as if it is lightly touched, it will turn into powder. By twisting it with your hands, it feels delicate, like fine sand flowing between your fingers.
The density of realgar is slightly larger than that of ordinary things. When placed in the hand, it feels quite heavy and seems to contain endless power. Its crystal structure is unique, often in a block or granular aggregate. Under the light, it can be seen flickering slightly, as if the light is introverted, emitting a mysterious atmosphere.
Furthermore, realgar has a certain melting point. When heated to a specific temperature, it will melt into a liquid state. This property is also one of its important physical properties. And it is insoluble in water. Even if it is immersed in water for a long time, it can maintain its own shape and properties, just like a hidden person who sticks to itself and does not blend with water.
In addition, realgar is relatively stable in the air. However, when exposed to heat or specific chemicals, chemical reactions will occur, showing characteristics that are different from the norm. The physical properties of this mineral medicine have important applications in ancient alchemy, pharmaceuticals and other fields. The ancients used its unique properties to exert its many effects, adding a strong touch to the development of traditional medicine and related skills.

Arsenic disulfide is the main component of realgar. During the production process, many matters need to be carefully paid attention to.
The first thing to pay attention to is the selection and treatment of raw materials. To obtain pure arsenic disulfide, high-quality ores need to be selected as the source, and the ores need to be finely ground to make their particle size appropriate, so as to facilitate subsequent reactions. This process is like the selection of materials recorded in "Tiangong Kaiwu". All materials must be well selected before they can be used as the basis for the product.
The control of reaction conditions is particularly critical. Temperature, pressure, and reaction time all need to be accurately grasped. If the temperature is too high, it may cause arsenic disulfide to decompose and deteriorate; if it is too low, the reaction will be slow and the yield will be low. Just as "Tiangong Kaiwu" talks about many firing and smelting processes, the control of the temperature is related to success or failure, and the same is true. Pressure and reaction time also have their own degrees, and neither too much nor too much is a good fruit.
Furthermore, the safety of the production environment cannot be ignored. Arsenic disulfide has certain toxicity, and the production site must be well ventilated to prevent the accumulation of harmful gases and endanger the health of workers. During operation, workers should prepare protective equipment, such as masks, gloves, etc., to avoid direct contact with materials. This is the weight of human life. Although "Tiangong Kaiwu" does not elaborate on such protection, the idea of safe production is the same in ancient and modern times.
Maintenance and cleanliness of production equipment are also important matters. Periodically inspect the equipment to ensure its stable operation and no risk of leakage. The equipment is not clean, or impurities may be mixed in, which will damage the purity of the product. This is like the care of the utensils in "Tiangong Kaiwu" to ensure its long-term use and the quality of the goods.
The quality inspection link is essential. Products at each stage should be carefully inspected to measure their purity, composition and other indicators. If they are not up to standard, the process should be adjusted immediately to ensure that the final product is of high quality. This is the essence of becoming a good thing, and "Tiangong Kaiwu" is also the quality of heavy objects. The same is true.

In today's world, arsenic disulfide is realgar, and the price trend of its market is related to various reasons.
Guanfu's place of origin, if the production of realgar is prosperous in a certain place, its place is close to the market and it is convenient to lose, the price will be flat. If the product is rare and difficult to lose, it will increase greatly through long-distance transshipment, and the price will be high. It is because of the distance of the place of origin, the abundance of the product, and the movement of the price, which has a huge impact.
Looking at the situation of demand again, realgar is used in the pharmaceutical, chemical and other industries. Medicine seeks to increase, and new uses are developed, the demand for realgar will be prosperous, and the price will also rise. If the market wants to be weak, the road to use is narrow, and the price may < Br >
There are also political regulations, and the government sets taxes and regulations. If the tax is heavy, the cost of business will be high, and the price will rise due to it. The regulations are strict, the mining and system are limited, the production is small, and the price also rises.
And with the changes of time, in ancient times, realgar was plagued by the epidemic. When the epidemic broke out, it sought a sharp increase, and the price soared. Although it is different today, it has not been used up, and the changes of time may still cause the need to move, so the price will shift.
The competition in the city, there are many producers, and the supply exceeds the demand. In order to compete for customers, the price will be reduced. If there are few producers, or control their production, the supply will be less and the demand will be more, and the price will rise.
The price trend of realgar is a mixture of factors such as origin, demand, government, time, and competition. Businesses and profit-makers can only know the change of price when they carefully observe the situation and judge the situation.

Arsenic disulfide, also known as realgar, and its impact on the environment are detailed as follows:
The main component of realgar is arsenic disulfide. In the natural environment, if realgar is weathered, rained or migrated with water flow, the arsenic element in it will be gradually released, resulting in increased arsenic content in surrounding soils and waters. If the arsenic content in soil is too high, it will change the chemical properties of the soil, affect the structure and function of soil microbial communities, and then inhibit plant growth. Plants absorb too much arsenic, which can cause physiological and metabolic disorders, hinder growth and development, and reduce yield and quality. Arsenic can be enriched through the food chain, threatening animal and human health.
In the water environment, the dissolved arsenic of realgar can cause water quality to deteriorate. Arsenic exists in various forms in water, some of which are highly toxic. Excessive arsenic content in water will endanger the survival of aquatic organisms. Aquatic animals such as fish are in arsenic-containing water for a long time, and they will experience slow growth, reduced reproductive capacity, and physiological diseases. At the same time, if humans drink water containing arsenic exceeding the standard, it is easy to cause a variety of diseases, such as skin lesions, cancer, etc.
In addition, when realgar is heated or burned, more toxic substances such as arsenic trioxide (arsenic) will be formed, which will evaporate into the atmosphere and pollute the air. These toxic substances diffuse through atmospheric circulation and have a wider impact. They will be inhaled by the human body, harming the respiratory system and other organs. And after the arsenic in the atmosphere settles, it will enter the soil and water bodies, forming circular pollution.
In summary, although realgar has certain uses in traditional fields, its potential harm to the environment cannot be underestimated. In the process of mining and use, appropriate measures need to be taken to reduce its negative impact on the environment and maintain the ecological environment and human health.
