2-(Thiophene-3-yl)ethanol

It is reported in "Tiangong Kaiwu" that where burnt stone is turned into ash, lime is used as the bulk. In the preparation of raw lime, the main use of 2 - (kiln gas - 3 - base) acetylene flame is a key link in the firing of lime.
The kiln gas is the gas generated by the combustion in the kiln. When firing lime, this gas can create a specific environmental atmosphere, help the fuel to burn fully, and provide enough heat to promote the decomposition of limestone. 3 - base Under specific processes, the reaction conditions may be adjusted to optimize the reaction process.
As for the 2 - (kiln gas - 3 - base) acetylene flame, its primary use is to provide a high-temperature heat source. In lime firing, limestone (calcium carbonate) needs to be decomposed into calcium oxide (lime) and carbon dioxide at high temperature. This acetylene flame can generate high temperature, so that limestone reaches the decomposition temperature. Its high temperature can quickly promote the change of calcium carbonate lattice structure, chemical bond breaking, and efficient decomposition.
And the flame has good stability, can maintain high temperature for a long time, and ensure the continuous and stable decomposition reaction of limestone. In the ancient lime firing process, it is extremely important to stabilize the heat source. If the temperature fluctuation is too large, or the decomposition of limestone is incomplete, it will affect the quality of lime.
Furthermore, the 2- (kiln gas-3-based) acetylene flame can precisely control the temperature area. Craftsmen can adjust the position and intensity of the flame according to the needs of different locations in the kiln, so that the limestone in the kiln can be fully decomposed, improving the output and quality of lime, and playing an indispensable role in the traditional process of lime firing.

Mercury is one of the hardware, which is naturally fluid. It is a liquid metal. At room temperature, silver light shines, agile and indeterminate, like a flowing bead. With its special physical properties, it is wonderfully useful in many aspects.
The melting point of mercury is very low, about -38.87 ° C. Therefore, in ordinary environments, it is in a flowing state. This property makes it easy to disperse, penetrate, and can enter tiny gaps. Its boiling point is 356.6 ° C. It is easily volatile when heated and turns into mercury vapor. This gas is colorless and odorless, but toxic. It should not be careless.
The density of mercury is quite high, about 13.59 g/cm ³. Compared with common metals such as iron and copper, the density is significantly higher, so it feels heavy. Due to its high density and incompatibility with water, it often exists in the lower layer of water. If placed in a container, it can be seen that the mercury liquid sinks at the bottom of the water, and the boundary between it and the water is clear.
Mercury has good electrical conductivity. Although it is not as good as metals such as gold, silver, and copper, it can also be used as a conductive material under certain conditions. And mercury has good thermal conductivity and can quickly transfer heat.
Mercury and other metals can form amalgam, which is the unique property of mercury. The formation of amalgam may change the characteristics of metals, such as hardness and melting point. Many metals can form amalgam with mercury, such as sodium, potassium, zinc, etc. This property is widely used in metallurgy, dental fillings and other fields.
However, mercury is toxic, and its vapors and compounds can cause poisoning and damage the nervous system, kidneys and other organs. Mercury poisoning has various symptoms, including headache, dizziness, fatigue, convulsions, coma, and even life-threatening in mild cases. Therefore, when using mercury, strictly follow the operating procedures and take good protection to prevent the risk of mercury poisoning.

2-%28%E5%99%BB%E5%90%A9-3-%E5%9F%BA%29%E4%B9%99%E9%86%87%E7%9A%84%E5%8C%96%E5%AD%A6%E6%80%A7%E8%B4%A8%E5%A6%82%E4%B8%8B%EF%BC%9A
This is a strange thing, with various unique chemical properties. First, the stability is extraordinary. Under many common chemical environments, 2-%28%E5%99%BB%E5%90%A9-3-%E5%9F%BA%29%E4%B9%99%E9%86%87 can be stable in it, and it is not easy to react violently with the surrounding substances. It is like the tranquility of being alone, and it is not easily disturbed by the outside world. Just like the hermit of ancient times, in the chaotic world, he is indifferent and unmoved by the noise.
Second, its solubility is quite specific. In some specific solvents, it can dissolve quickly, just like ice melting in water, without blockage. In other solvents, it is as solid as a rock, and there is no sign of dissolution at all. This characteristic is like a wise man's choice of friends. In front of the suitable one, they are in love with each other and blend seamlessly; in front of the unsuitable one, they stick to themselves and are not lured.
Third, the acidity and alkalinity are also considerable. Under specific conditions, it can show weak acidity and can react quietly with alkali substances, just like spring rain moisturizing the body, changing the surrounding environment in a silent place. In other situations, it shows alkaline characteristics and interacts with acidic substances. This unpredictable state is like yin and yang changing, mysterious and unpredictable.
Fourth, the redox property is unique. When encountering strong oxidants, it can be slowly oxidized, but the process is stable, not as intense and rapid as others. In the face of reducing agents, reduction reactions can also occur, as if on the stage of redox, performing a unique dance, following a unique rhythm and rhythm.
These chemical properties make 2-%28%E5%99%BB%E5%90%A9-3-%E5%9F%BA%29%E4%B9%99%E9%86%87 have potential uses in many fields, such as the production of wonderful medicines and the creation of strange things.

If you want to make two - (arsenic-three-mercury) medicine, there are all kinds of wonderful techniques for its synthesis, let me come one by one.
First, in a clean place, prepare refined utensils. Choose good arsenic, you need pure color and quality, and no impurities are mixed in. Arsenic is fierce and poisonous. When using it, you must be cautious to prevent touching the body. Three - Mercury also needs to be carefully selected, and a pure texture is preferred.
Put arsenic in a special crucible and heat it slowly. The size of the fire is very important. If the fire is large, the arsenic will easily melt and dissipate, and if the fire is small, it will be difficult to achieve the desired state. When the arsenic changes color slightly, it seems to melt, then cease fire.
Take another three-mercury, place it in another clean crucible, and heat it at a moderate heat. Mercury, flowing like mercury, should be paid close attention when heating, and stop when you see it smoke slightly.
Then, pour the heated arsenic slowly into the heated three-mercury. When pouring in, the speed should be slow, and at the same time gently stir with a special bamboo chopstick to mix the two evenly. At this time, it can be seen that the contents of the pot are slightly rolled, and there seems to be a strange change.
After stirring, move the mixture into a special condensing container. The container needs to be cold and clean, so that the mixture can be quickly condensed and formed. When condensing, do not slack off, you need to pay attention to the surrounding environment, and do not let any debris fall into it.
After forming, take out the prepared medicine. Looking at its shape, when the color is uniform and the texture is delicate. However, this medicine is highly toxic. After it is made, it must be filled with a special sealing appliance, properly stored, and cannot be placed at will to prevent others from accidentally touching and misusing it, causing major disasters.
This is a general method for the synthesis of two - (arsenic-three-mercury) medicine. The subtleties in it need to be carefully studied according to the actual situation before the manufacturer can obtain the delicate medicine.

It is appropriate for those who should pay attention to the matter of hiding.
The hidden place is the first place. It is appropriate to avoid exposure to light and avoid it due to high tides. If it is placed in a tidal place, the two - (the three-foundation) or the invasion of the water will cause the product to be damaged and the effect will be weak. Moreover, the hidden equipment should not be ignored. It is appropriate to use containers that are thick and dense, which can not only prevent the soil from being damaged, but also prevent the air from being mixed in, so as to ensure its safety. If the appliance is not damaged, it is easy to contaminate the second - (3-base), and it will lead to undesirable melting.
It is necessary to fix the second - (3-base) properly to avoid shaking and collisions on the way. If the process is rough and severe, it may cause it to break and shape, which will affect its original effectiveness.
The environment of
also needs to be considered. Keep the appropriate temperature and temperature, and do not make it suffer from the weather. Hot summer and cold may cause damage to the second - (3-base). Such as high heat in summer, or cause it to melt or burn; cold in winter, or cause it to crack or burn.
In addition, the amount of heat loss is also short. After a long time, the longer you are exposed to the outside world, the more you encounter problems, and the greater the possibility of the product being affected. Therefore, if you hide or hide, you must take care of it carefully, and pay attention to the general situation, so as to ensure that the effectiveness of the second- (third-base) product is not low.
