What are the chemical properties of 3-iodine-9-phenyl-9H-carbazole?
9H arsenic is highly toxic. Its chemical properties are unique, and the main component of arsenic is arsenic trioxide ($As_2O_3 $).
From a chemical point of view, arsenic trioxide is an amphoteric oxide, which can react with both acids and bases. When exposed to acid, the corresponding arsenic salt can be formed. If reacted with hydrochloric acid, arsenic trichloride and water will be formed. When reacted with alkali, arsenite and water will be formed.
And arsenic has certain oxidizing properties. Under certain conditions, it can oxidize certain substances. For example, it can oxidize sulfur in hydrogen sulfide.
However, its toxicity is the key. After arsenic enters the human body, it will combine with the sulfhydryl groups of various enzymes, which will cause the enzyme to lose its activity and seriously interfere with the normal physiological and metabolic process of the human body. Many important enzymes such as pyruvate oxidase are affected by it, causing cell metabolic disorders and ultimately endangering life.
In ancient times, arsenic was often used as a poison. Because of its appearance similar to some common substances, such as flour, it is easy to poison and difficult to detect. In addition, its toxicity is violent, and a small amount can cause death, so it has become a common weapon for bad people. Even today, arsenic needs to be strictly controlled to prevent it from flowing into illegal channels and endangering people's lives. In short, 9H arsenic has always been vigilant because of its highly toxic and special chemical properties.

If it is overheated, move it to a cool place to prevent it from spoiling; if it is too cold, add clothes to cover it and help it ferment. When its smell is fragrant and the taste is correct, it is complete. When it is used, use a purifying vessel to wash it, remove its waste, and you can get clear plum. This is the general idea of making plum in the ancient method, but the subtleties still need to be carefully understood by the maker before you can get the wonders of fine wine.
What is the market prospect of 3-iodine-9-phenyl-9H-carbazole?
Since modern times, the future of the 3-9-Yingji 9H-wine market has been promising. In today's world, the people will be released, and the banquets will be intertwined. This wine is still suitable for the world because of its unique craftsmanship. It contains a mellow taste. It has a unique style among the best. Therefore, it is popular with the world.

What are the precautions in the preparation of 3-iodine-9-phenyl-9H-carbazole?
The method of making wine involves many taboos, so we must be cautious.
The first choice of materials, the grain should be the best. The grain should be full, no mildew, no moth-eaten, this is the foundation of wine quality. If the grain is not good, the taste of the wine will be bad. Such as millet, rice, etc., each has its own characteristics, according to the category of wine.
The second is water, which is the blood of wine. It is appropriate to use sweet and clear springs, the water quality is pure, no odor, no impurities. The water of rivers needs to be precipitated and filtered to remove its pollution before it can be used. The quality of water is directly related to the flavor of the wine.
Furthermore, making music is essential. Qu is the bone of wine, and its production depends on the solar terms and temperature. Summer is hot, Qu is prone to change, and it is suitable for spring and autumn, and when the climate is mild. When Qu is fermented, its heat needs to be checked. If it is too bitter, it will taste bitter, and if it is not, it will taste light.
When fermenting, temperature control is essential. If the temperature is too high, the wine will be easy to rancid; if the temperature is too low, the fermentation will be slow. The temperature of the cellar must be suitable, or according to the weather, or by manual regulation, so that the leaven can be leavened in its place.
The method of distillation is also exquisite. The heat should be stable, and if the fire is fierce, the wine will be rough, and if the fire is slow, the wine will be scarce. The distillation apparatus
When storing, the choice of utensils is different. The pottery altar is the best, and its air permeability is good, which can make the wine communicate with the outside world slightly and mellow its taste. Wine should be stored in a cool and dry place, protected from direct sunlight, to prevent its quality from changing. As the years go by, the wine becomes more fragrant as it ages.
All these are essential for winemaking. If there is a slight mistake, the flavor of the wine will be lost. Craftsmen need to be in awe and abide by the ancient laws in order to make good wine.
