Thiophene-alpha-sulfonamide

"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty, and its writing style is simple and rigorous. However, because I don't know what the expression "arsenic-α-arsenic oxide" means in ancient books, the following is based on modern chemical knowledge and antique writing style:
Arsenic, the traditional understanding is mostly arsenic trioxide ($As_2O_3 $), which is a highly toxic thing. If it is called "arsenic-α-arsenic oxide", or refers to a specific crystal form or form of arsenic oxide.
Arsenic oxide is acidic oxide. It can combine with alkali substances, such as meeting with sodium hydroxide ($NaOH $), and can produce sodium arsenite ($Na_3AsO_3 $) with water. The reaction formula is: $As_2O_3 + 6NaOH = 2Na_3AsO_3 + 3H_2O $.
In the heated state, in case of strong oxidants, such as oxygen ($O_2 $), under certain conditions, it can be further oxidized to arsenic pentoxide ($As_2O_5 $).
Arsenic-α-arsenic oxide has limited solubility in water, and its aqueous solution is weakly acidic, because it can weakly ionize hydrogen ions ($H ^ + $). < Br >
And because it contains arsenic, many arsenic compounds are toxic, because it can interfere with the activity of many enzymes in the biological body, cause cell metabolic disorders, damage the function of human organs, and endanger life. The world should use it with extreme caution and must not ignore its harm.

Arsenic - α - arsenic trioxide, its main use is quite complex, and it involves dangerous or special fields.
In the field of medicine, in ancient times, doctors tried to treat diseases with trace amounts of arsenic. According to ancient records, arsenic has long been used as medicine to treat sores and carbuncle swelling. To modern times, through scientific research and technology, α-arsenic trioxide has shown special effects in the treatment of leukemia. For some types of leukemia, moderate use can induce cancer cell differentiation and apoptosis, bringing vitality to leukemia patients.
In the field of agriculture, it was used as an insecticide in the past. Because of its toxicity, it can kill a variety of pests and protect the growth of crops. However, due to its highly toxic, easy to remain in soil and crops, endangering ecology and human health, it is rarely used today.
In the industrial field, α-arsenic trioxide can be used in glass manufacturing. Adding it can eliminate bubbles in glass and improve the transparency and quality of glass. In the metallurgical industry, it is also used as an additive for some metal smelting to improve metal properties.
However, it should be emphasized that arsenic - α - arsenic trioxide is extremely toxic, and if used carelessly, it will endanger life. Its applications in medicine, agriculture and industry must strictly follow norms and safety standards, and be operated by professionals. It must not be ignored because of its use.

"Tiangong Kaiwu" is an ancient scientific and technological book of our country, detailing many methods of process production. However, today I want to say that the synthesis method of cyanoacrylic acid is not exactly compatible with it. This is because the woman - α - cyanoacrylic acid is a modern chemical product, and the chemical cognition and technology in ancient times are far less than today.
However, if the ancient chemical process thinking is extrapolated, the synthesis method may need to go through multiple steps of exquisite operation. First of all, when finding suitable raw materials. In ancient times, there were examples of minerals, plants, etc. as raw materials to make various substances. For the synthesis of cyanoacrylic acid - α - cyanoacrylic acid, or the need to find cyano- and acrylic-related raw materials.
Secondly, it is necessary to clarify the proportion and conditions of the mixing of raw materials. Ancient alchemy, pharmaceutical and other processes are all very heavy raw material ratios and reaction conditions. Synthesis of cyanoacrylic acid - α - need to precisely control temperature, humidity, etc. Such as ancient alchemy, the control of the heat is extremely strict, and the products are very different from different heat conditions.
Furthermore, the reaction process may require the help of appropriate equipment. In ancient times, there were special alchemy furnaces, decoction kettles, etc., in the synthesis of - α - cyanoacrylic acid, or need to design a suitable container to make the reaction go smoothly.
Although the ancient process is difficult to compare with today's chemical synthesis, it pays attention to the thinking of raw materials, proportions, conditions and utensils, which may provide a different perspective for the synthesis of - α - cyanoacrylic acid. However, the exact synthesis method still depends on the system theory and advanced technology of modern chemistry.

Mercury - α - mercury chloride, all things hidden and lost must not be careless. Mercury is highly toxic and harmful to both the human body and the environment.
When storing mercury - α - mercury chloride, the first thing to do is to choose a good place. It should be dry, cool and well ventilated, away from direct sunlight. If it is wet, it is easy to phase with water vapor, causing its qualitative change, toxicity or increase. Direct sunlight can also cause its chemical changes, causing unexpected harm. And the reservoir must be firm to prevent damage and leakage. Once mercury - α - mercury chloride leaks out, it will pollute the soil when it enters the ground, and it will poison the water source when it enters the water, which is a far-reaching disaster.
Furthermore, the container must be selected carefully. Glass or special plastic containers should be used, because they are resistant to corrosion and can prevent mercury - α - mercury chloride from corroding with them. And the container must be tightly sealed to prevent it from passing through the air with the outside, so as to prevent it from evaporating in the air. If people absorb it, it will damage their health.
As for the time of transportation, the escort must be fine in his work, showing that mercury - α - the nature of mercury chloride. The transportation equipment must also be fit, shock-proof and leak-proof. Avoid bumps on the way, if the equipment is damaged and leaks, its harm will appear. And the journey of transportation must be carried out in accordance with regulations, do not change the route without authorization, do not approach places where people are densely populated, and avoid water sources, just in case of leakage and harm to everyone.
Where mercury - α - mercury chloride is involved in the storage and transportation, it should be treated with caution. One person's negligence may cause disaster to the people; a moment of neglect can lead to long-term trouble. Therefore, everything must follow the rules, and must not be sloppy at all, so as to ensure safety.

Since modern times, the study of medicine has been advancing day by day, but the market prospect of epilepsy - α - hyaline cytoma is also the common attention of doctors and drug dealers.
At present, the disease of epilepsy - α - hyaline cytoma is not as serious as many people, but its disease is lingering, and every patient suffers. And the pathology of this tumor is complicated and the treatment is very difficult, so the medical community is paying more and more attention to it, and it is eager to research new techniques and new drugs.
From one end of the market, its prospects can be said to be broad. Because there are many unfinished needs at present. First, the accuracy of diagnosis needs to be improved. Today's diagnostic methods may have the risk of missed diagnosis or misdiagnosis. If accurate techniques can be created, they can be explored and the subtle characteristics of this tumor can be identified. It must be valued by the medical community, and its market potential goes without saying. Second, the road to treatment also needs to be developed. Today's therapies may not be fully effective, or have many side effects. If special drugs can be made, which can not only eliminate tumors, but also reduce the pain of patients, and are safe and secure, they will be popular in the world and widely favored by patients. In the market, they will also take the lead.
Furthermore, with the growing awareness of public health, more attention will be paid to the early prevention and treatment of diseases. Although epilepsy - α - hyaline cytoma is a niche disease, it is also among the public's concerns. If we can develop a method suitable for early screening, it is simple and convenient, and can enable the public to self-check and detect hidden dangers in advance, it will definitely open a new market.
As for pharmaceutical companies, if they can gain insight into this opportunity, dedicate themselves to the research and treatment of epilepsy - α - hyaline cytoma, gather wisdom, gather good materials, and make good medicines, which can not only solve the plight of patients, but also make great profits in the market. Therefore, the market prospect of epilepsy - α - hyaluronas is waiting for people of insight and enterprises to explore and explore, and its future prosperity is still limited.
