What are the chemical properties of 2-Iodoaniline?
"The nature of this material is extremely cold, and when it enters the water, although it is extremely hot and the moon is hot, the air of frost and snow is cold." The person in question is saltpeter.
Saltpeter has unique chemical properties. First, it has strong oxidizing properties. In the art of fire attack, saltpeter can make combustible materials burn rapidly, just like a fire dragon raging. In ancient wars, saltpeter was attached to firearms, and when a fire broke out, the enemy would be in chaos. For example, in the rocket of the Song Dynasty, saltpeter was bound to arrowheads, and when it burned, it shot the enemy. The fire soared into the sky, and its power was amazing. This is because saltpeter releases oxygen when exposed to heat, and its ability to support combustion is significant.
Second, when saltpeter dissolves in water, it absorbs a lot of heat. In the heat of summer, take a basin of water and throw saltp The ancients took advantage of this property to make ice in summer to cool down. The principle is that saltpeter dissolves and absorbs heat, causing the temperature of water to drop below freezing point, and then becomes ice. Such wonderful uses are really a manifestation of wisdom.
Third, saltpeter can react with many metal salts. When alchemy was popular, alchemists co-refined saltpeter with metal compounds such as lead and mercury, which changed thousands of times, or changed color, or morphological transformation. Although the chemical principle was not known at that time, he accumulated a lot of practical experience, laying the groundwork for the development of later chemistry.
The chemical properties of saltpeter are wonderful, and it has extraordinary performance in military, life, alchemy and other fields, witnessing the ancient people's exploration and application of material properties.
What are the physical properties of 2-Iodoaniline?
In "Tiangong Kaiwu", the physical properties of ramie are unique. The color of ramie is often white, and the appearance is pure and elegant. This is a significant physical characteristic of its appearance. When touched by hand, the texture is quite good, and it has a smooth feeling. And its fibers are flexible, not easy to break when stretched, showing good flexibility and strength.
The fibers of ramie are slender and uniform, which is crucial for many applications such as textiles. Its length is suitable, and when woven into threads, it can make the woven fabric uniform and tight. In addition, the fiber thickness is consistent, making the surface of the fabric more flat and smooth, and comfortable to the touch.
Furthermore, ramie has good moisture absorption and heat dissipation properties. In summer, ramie fabrics can quickly absorb the sweat excreted by the human body and quickly disperse into the surrounding air, making people feel dry and not feel sticky and uncomfortable due to sweat accumulation. This characteristic makes ramie fabrics popular in hot seasons.
At the same time, ramie also has certain antibacterial and mildew-proof properties. Under proper storage conditions, it is not easy to be eroded by molds and can also inhibit the growth of bacteria, thus prolonging the service life of ramie products and reducing many worries for users in daily life.
It can be seen from the above that ramie occupies an important position in ancient fabric raw materials due to these unique physical properties. It is widely used in clothing, home textiles and many other fields, bringing many conveniences and comforts to people's lives.
What are the common uses of 2-iodoaniline?
2-% toad crisp is the white liquid secreted by the ear glands and skin glands of toads, which is processed. It has many common uses in this and other fields, and is described as follows:
1. Use
1. ** Detoxification and disinfection **: This is one of the important functions of toad crisp. In ancient recipes, it is often used to treat various poisonous pains. In case of boil, boil, etc., it can be used externally to detoxify and dissipate. Because of its ability to disperse and disperse, it can be treated, so that the poison has a way out, and the purpose of detoxification and disinfection.
2. ** Analgesia **: Toad crisp has a good analgesic effect. It can be used if it is toothache, stomach pain, or surgical pain. Toothache, with a small amount of toad crisp research end, put on the toothache, can quickly relieve pain. Its pain-relieving principle is to go through the incense, which can pass the blood, so that the blood can pass, "no pain", and the blood can stop the pain.
3. ***: The middle of the toad crisp is entered, and the middle of the brain has a function. It can improve the function of the heart, increase the capacity of the heart muscle, and increase the blood pressure. In some critical and serious diseases, such as heart weakness, shock, etc., the rational use of the toad crisp may save the dying life. This effect is similar to that of the ancient family.
2. Other uses
1. ** For perfume **: Toad cake has a special smell. In perfume production, it can be used as setting incense. It can make the fragrance of the perfume last longer and give the perfume a special smell. As in a large scent, it is formed into a fixed color element, and the whole fragrance is more rich and rich again.
2. ** Use **: In the field, Toad cake is also useful. It can be used to detoxify and disinfect certain toxicological diseases of livestock and poultry. This is because the diseases of livestock and poultry are similar to humans, and the effect of Toad cake can also be applied to them, so as to protect the health of livestock and poultry and improve the development of animal husbandry.
What is the preparation method of 2-Iodoaniline?
The method of making partridge paste is not clearly recorded in "Tiangong Kaiwu". The following is your speculation on the method of making partridge paste from other ancient records and related studies:
Partridge paste, or the fat taken from partridges. To make partridge paste, the first thing to do is to catch a partridge. Partridges mostly live in the mountains and forests. They are lively and like to hide. It is necessary to catch them skillfully. Or use the sound of luring birds to lure them, set up a net to wait, and catch them while they come.
After getting a partridge, the method of taking the paste, or the practice of taking animal oil as the ancients. After the partridge is killed, carefully separate its skin and flesh, and take its fat. Another possible method is to use gentle means, such as proper massage of the fat-rich areas of the partridge, to promote the oil to seep and collect when the partridge is alive.
The partridge paste collected needs to be properly disposed of. Or put it in a clean container and boil it slowly over low heat, stirring constantly in the meantime to fully separate the oil. When boiling, the heat is very important. If the fire is fierce, the paste will be easy to burn and lose its effectiveness; if the fire is small, it will take a long time and the oil will not come out. When the oil is completely boiled out, its impurities will be removed, and pure partridge paste can be obtained after cooling.
However, due to the changes of the times, many details of the ancient method may have been lost. The above is speculated in combination with the method of preparing common animal oils in ancient books. Nowadays, partridges are mostly protected animals, and illegal hunting is strictly prohibited. It is impossible to make partridge paste, which is only a historical and technical discussion.
What are the precautions for using 2-iodoaniline?
First, toad crisp is a precious raw material, and it is not necessary to use it.
First, toad crisp is toxic, and it must be followed. Do not increase the amount without authorization. If the degree of loss is used, it will vomit, dazzle, and endanger life. There are ancient books that have been written for a long time. As the "Materia Medica" says: "Toad crisp is refreshing in taste, poisonous in nature." Therefore, if it is not used, it cannot be used.
Second, it is very important to distinguish the truth. The city's raw materials are mixed, and there is no shortage of adventurers. The real toad crisp color is brown, the ground is hard, the surface is slightly shiny, and the smell is special. The taste is initially sweet and has a lasting spicy feeling. If the color is not normal, the taste is not bad, and the place is not good, then add the identification, so as not to use the product, which will not only benefit the disease, but also cause the bad end.
Third, proper storage should not be ignored. Toad cake should be stored in the dry air, and it should be kept in secret to prevent moisture absorption. The tide is easy to cause its mildew and rot, and the shadow is not good. Gu Yun: "The way to hide the wood is that it can last for a long time." The key to hiding is to avoid the tide, prevent the wood, and protect its essence.
Fourth, compatibility should be avoided, and the heart should be clear. The combination of certain substances in toad cake may increase the toxicity or reduce the effectiveness. If the toxic products such as Sichuan and grass are compatible, the toxicity may be doubled. If you use it, it will pass the quality of the product, and it should be avoided in order to improve its effectiveness and reduce the drawbacks.
Of course, 2-% of the toad cake has a miraculous effect, but the use of the product, toxicity, authenticity, hiding, compatibility and other things, are all important to ensure safety and effectiveness, and save people from illness.
