thiophene-3-ethanol

"Arsenic is as fierce as wolves and tigers, and its poison is good." Arsenic, or arsenic trioxide, has unique physical properties.
Arsenic usually appears as a white powder with a delicate texture, like fresh snow in winter. It seems pure and harmless, but it is actually dangerous. It is relatively stable at room temperature and pressure, and will not easily decompose on its own or react violently with common ingredients in the air.
Its density is relatively large, and it feels slightly heavy compared to common powders. Arsenic has no special smell. If it is only by smell, it is difficult to detect its existence, which also makes it more hidden, and it is easy to be caught when unprepared.
Arsenic has a certain solubility in water, but the dissolution speed is not rapid, and the amount of dissolution is limited. When placed in water, it will initially be suspended like a powder, and over time, some of it will slowly integrate into the water, making the water slightly cloudy.
In addition, arsenic has a relatively high melting point, and it needs to change from solid to liquid under certain high temperature conditions. During the heating process, it does not produce obvious phenomena such as burning or black smoke like some organic matter, but quietly melts, still maintaining its seemingly harmless appearance, but its toxicity is always hidden in it, and it has not been reduced at all. This kind of physical property not only shows its uniqueness as a substance, but also makes it an awesome existence due to its toxicity.

The chemical properties of ethyl boron are particularly peculiar. It is light and alive, and often shows a lively state.
When ethyl boron encounters water, it reacts quickly. Water is an ordinary liquid, but when it encounters ethyl boron, it suddenly changes. When ethyl boron enters water, it is like a flood dragon getting rain. It quickly hydrolyzes, escapes hydrogen, and generates boric acid. This reaction is intense and fast, like a starfire burning in Artemisia wilt, showing the vitality of ethyl boron.
In the air, ethyl boron is also restless. Air, everything depends on, but when it encounters ethyl boron, it is easy to spontaneously ignite. Its combustion is like a torch, releasing a huge amount of heat, and forming boron trioxide. Looking at the burning scene, the flame is dazzling, which shows the strong affinity of ethylene boron and oxygen.
When ethylene boron meets alkali, it also undergoes a wonderful change. Alkali is more neutral in nature, while ethylene boron reacts with it to generate borate and hydrogen. This reaction also shows the unique properties of ethylene boron.
And ethylene boron can interact with many metals. Metals are stable in quality, but ethylene boron can combine with some metals to form metal borides. These compounds are either specific or have different properties, and may be useful in the field of materials.
Furthermore, ethylene boron also has an extraordinary position in the field of organic synthesis. Due to its active nature, it can be used as a reagent, triggering many organic reactions, assisting in the synthesis of organic compounds, and adding a sharp tool to the research of organic chemistry.
From this perspective, the chemical properties of ethyl boron are active and changeable. In various reactions, it shows its unique quality, and it is an important thing in the field of chemistry that cannot be ignored.

"Arsenic, the descendant of tin, is the most ferocious, like poison, but it is also useful in various fields."
Arsenic, in the field of medicine, in ancient times, trace amounts of arsenic were used as medicine. Although arsenic is highly toxic, it can be used to treat certain diseases after being processed and strictly controlled in doses. For example, in some ancient medical records, it can be seen that arsenic is used to treat sores, malaria and other diseases. In the past, people said: "The poison is used to fight poison, and arsenic is used to make ointment, which is applied to acne, which can eat carrion and promote new muscle growth."
In the field of metallurgy, arsenic is also useful. In the ancient process of tin refining, arsenic was used as a companion. Although it was harmful, it could be used properly to help separate impurities and improve the purity of the metal. As stated in "Tiangong Kaiwu", "When tin is smelted, arsenic may help to separate impurities and make the tin purer."
In the field of agricultural pest control, arsenic has also been tried to use. The ancients observed the toxicity of arsenic, and mixed it with certain substances to make an insect repellent and sprinkle it on the farmland to repel pests. As the agricultural saying goes: "A little arsenic is mixed in the soil, and pests are avoided."
However, it needs to be clear that arsenic is highly toxic, and extreme caution must be used when using it. If you are not careful, it will endanger the lives of humans and animals and cause disaster. Therefore, in the application of arsenic, the ancients must follow strict laws to ensure safety.

The synthesis method of arsenic-3-ethyl alum in "Tiangong Kaiwu" is related to the key techniques of chemical industry. The method is as follows:
A certain amount of ethyl alum needs to be prepared. This alum is feminine, delicate in texture, and blue in color. It is the base material for synthesizing arsenic. First, clean the kettle and heat it with charcoal fire, so that the wall temperature is uniform, and there is no risk of uneven heat and cold. When the kettle is heated through, pour the ethyl alum fragments slowly into the kettle, and stir it frequently with a long-handled shovel to heat it evenly.
When the charcoal fire is burning, it is particularly critical. The fire should be stable and intense, not large or small. If the fire is weak, the melting of ethyl alum is slow and the reaction is insufficient; if the fire is fierce, the ethyl alum is easy to scorch and damage the foundation of synthesis. In the kettle, the ethyl alum gradually melts into a liquid, the color turns dark brown, and the smoke rises slightly. At this time, it is necessary to pay careful attention to the color and taste of the smoke, which is a sign of the reaction process.
When the ethyl alum is completely melted and turned into a viscous liquid, move the kettle to a ventilated place, but do not let the strong wind blow directly. Slowly cool, the liquid gradually coagulates, and the color turns dark. Take this clot and place it in a special ceramic urn. The wall of the urn should be thin and uniform to facilitate ventilation and heat dissipation. Spread fine sand at the bottom of the urn, about an inch thick, and lay the clot lightly on it.
Compound it with a slight fire to dry it. The firepower should be like the warm sun in spring, warm but not dry. Over time, the clot gradually changes, and white frost precipitates out. This white frost is the beginning of arsenic. However, the arsenic at this time still contains impurities and cannot be used.
Take clean water, gently sweep off the precipitated white frost, put it in another clean kettle, add an appropriate amount of water, and cook it slowly. When cooking, there is foam on the water surface, which needs to be skimmed off in time. Repeat this several times until the foam does not regenerate and the water is free of variegation.
Then pour out the solution from the kettle and filter it with multiple layers of fine cloth to remove its residue. The filtrate is placed in an open container and exposed to sunlight. When the water dries, the arsenic will become white as snow, pure and flawless, and can be used for medicinal or other purposes.
The method of synthesizing arsenic requires complicated steps. The heat, materials, and utensils need to be carefully controlled. If there is a slight mistake, the previous efforts will be in vain. Those who practice this technique must be cautious and careful in order to achieve success.

Looking at what you are asking "what is the market prospect of Coffin Ji-3-Yiji", I will analyze it with the ancient saying.
The market in which Coffin Ji-3-Yiji is located is changing in today's world, and there are many considerations. From the perspective of market demand, people now have different preferences, or love novel things, or prefer traditional styles. If Yiji is unique, with a distinct style, and suits some people's wishes, there are many buyers. If the craftsmanship and unique settings can attract attention and arouse their desire, the market demand may grow.
However, market competition should not be underestimated. Things of the same kind in all directions, such as crucian carp crossing the river, are pouring in. If Yi Ji wants to stand out, she must have something extraordinary. If it is of high quality and well-made, just like a well-crafted jade, it can stand out among all competing products. On the contrary, if it is shoddy, it will be abandoned by the market.
Furthermore, publicity and promotion are also the key. Gu Yun "The fragrance of wine is also afraid of deep alleys". Even if Yi Ji is so beautiful, it is not known to everyone, and it is difficult to have a broad prospect. It is time to use appropriate methods to advertise it widely. Or take advantage of various media channels, such as market announcements and letters, there are many new channels in this world, so that the name of Otsuji will be far and wide, and it will be heard by everyone, so as to increase its market influence.
And the market trend is changing rapidly. Otsuji must be able to adapt to the times and change with the trend. If you can see the opportunity, when the trend has not yet arisen, you will be prepared, and you will be able to take the lead in the market by launching the trend in a timely manner.
To sum up, the market prospect of Otsuji-3-Otsuji contains both opportunities and challenges. If you can grasp the demand, deal with competition, make good use of publicity, and conform to the trend, you may have a bright future; otherwise, you may be in trouble.
