What are the main uses of iodomethane and triphenylphosphonium?

"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty, which has far-reaching influence in many fields such as technological technology and agricultural production. For the arsenic stone and the three immortal pills mentioned in the question, its main uses are as follows:
Arsenic, the letter stone, is mainly composed of arsenic trioxide. In ancient times, arsenic was widely used. In the field of medicine, an appropriate amount of arsenic stone can be used as medicine after special processing. It is recorded in the "Compendium of Materia Medica" that arsenic stone can eat sores and remove rot, kill insects, rob phlegm, and cut malaria. However, its toxicity is very serious, and it needs to be used with extreme caution. In ancient times, some physicians would use arsenic stone to treat cold phlegm, asthma, malaria and other diseases, but a little carelessness would cause poisoning, so non-experienced physicians did not dare to use it easily. In industry, arsenic can be used to make glass, which can make the glass more transparent and improve the quality of the glass; in the metallurgical industry, it can be used as an additive to help improve the properties of metals. However, due to the strong toxicity of arsenic, it is harmful to the environment and the human body, and the precautions when using it need to be extremely strict.
Three immortal pills, the main ingredient is also mercury oxide. In ancient medicine, three immortal pills were often used in surgery, which had the effects of detoxification, decay and muscle growth. If the sore broke down for a long time, doctors often applied three immortal pills to the affected area to promote the shedding of carrion and the growth of new meat. However, three immortal pills contain mercury, which is also toxic. Improper use can also cause mercury poisoning and endanger human health. In ancient alchemy, the Three Immortals Pill was an important medicinal pill. Some alchemists believed that it had the effect of prolonging life and strengthening the body. Emperors and generals took it, but there were also many deaths due to mercury poisoning.
It should be made clear that arsenic and the Three Immortals Pill are both highly toxic. With the progress of modern science, the awareness of their toxicity has become more and more profound. Nowadays, they are rarely used in medicine, industry and other fields to avoid serious damage to the human body and the environment.

What are the physical properties of iodomethane and triphenylphosphonium?

The author of "Tiangong Kaiwu" was written by Song Yingxing in the Ming Dynasty, and it is a great achievement of technological technology. However, there are no "antimony armor beasts" and "triherbylbenzene" involved in it. As far as I know, I will describe the physical properties of these two for you.
Antimony armor beasts, a made-up name, there is no such thing in the world, so it is impossible to talk about their physical properties. If this is a misnomer of metal "antimony", antimony is brittle and hard, with a metallic luster, and its color is silver-white and slightly gray. Its melting point is quite low, only 630.63 ° C, and its boiling point is 1587 ° C. Antimony is still stable at room temperature, and it is not easy to react with oxygen and water. However, when it is heated with strong acids such as concentrated sulfuric acid and concentrated nitric acid, it can react chemically
As for triherbylbenzene, there is no name for this chemical, and it is speculated that it may be "trinitrobenzene". Take m-trinitrobenzene as an example. It is a yellow needle-like crystal with a bitter almond taste. The melting point is about 122 ° C. It is insoluble in water, but soluble in organic solvents such as ethanol, ether, and benzene. M-trinitrobenzene is chemically active, strong oxidizing and explosive. Because there are three nitro groups connected to the benzene ring, the nitro group is a strong electron-absorbing group, which reduces the electron cloud density of the benzene ring, so it is active. When heated, hit, or exposed to open flames, it is very easy to cause an explosion. In the field of organic synthesis, it is often used as

What are the chemical properties of iodomethane and triphenylphosphonium?

Antimony-lead ore is one of the minerals. Its chemical properties are quite characteristic. In antimony-lead ore, antimony and lead elements combine to form a unique structure.
From the perspective of chemical activity, antimony-lead ore is relatively stable at room temperature. However, in case of strong acid and strong base and other special chemical reagents, it will show different reactions. When encountering strong acid, the lead element in it may chemically react with it to form the corresponding lead salt. At the same time, antimony element may also react, and the products vary according to the type and concentration of acid.
In addition, tri-tellurium bismuth is also a unique mineral. Its chemical properties are also of concern. In bismuth tritelluride, bismuth interacts with tellurium. The chemical properties of bismuth are relatively stable, but tellurium is slightly more active. In air, bismuth tritelluride may undergo a slow oxidation reaction with oxygen, causing some changes in the color and properties of its surface. And in high temperature environments, the chemical stability of bismuth tritelluride will be affected, and the chemical bonds inside it may break and recombine, causing changes in the structure and chemical properties of the substance.
Compared with the two, antimony-lead ore is mainly dominated by antimony and lead, and its chemical properties are more reflected in the reaction with common chemical reagents against these two elements; while bismuth tritelluride is mainly bismuth and tellurium, and its chemical properties are greatly affected by the activity of tellurium, and the change is more significant under oxidation and high temperature. In short, both have their unique chemical properties and are of great value in the field of mineral chemistry research.

What should be paid attention to when storing and transporting iodomethane and triphenylphosphonium?

The first important environment is the storage and storage of the spoon dog and the three-hertz group. It is necessary to keep the dry and clear place to avoid the dark and the tide. The tide is easy to cause the spoon dog to rot, and the parts of the three-hertz group are also easy to be damaged and mildewed due to the tide, causing it to be damaged, and affecting its normal function. And the environment should also be kept stable to avoid the temperature. The temperature should be reduced, or the material of the spoon dog and the parts of the three-hertz group should be cold, causing poor joints or parts to be damaged.
Furthermore, the existence of magnetism. If the spoon dog is dried by magnetism, or causes its magnetism to be disordered, it will affect its normal use; there are many precision sub-components and mechanical parts in the trihedral part, and the magnetic component will also dry its operation, resulting in malfunction or mechanical failure.
It is very important to package the trihedral dog with appropriate materials, such as foam, soft fabrics, etc., to prevent shock and collision on the way. For this precision object, pay more attention to avoid strong shock. It can be tested to use the used packaging box and install multiple sensors to ensure that it can effectively resist external forces in the process.
In addition, it is necessary to follow the relevant rules and regulations during the flight, and pay attention to the environment of the tools. If you use the airport, you need to ensure that the environment meets the basic requirements for survival; if you use the airline, you need to be aware of the restrictions of some airlines on special items, and make an application in advance to ensure that the dog can arrive at the destination safely.

What are the preparation methods of iodomethane and triphenylphosphonium?

The preparation method of the turtle-stealing and the three-leaved base stele is related to the art of creation, and it is quite important. The ancient sages have been studied a lot in this country, and today they are described in ancient methods.
Those who steal turtles need to choose a beautiful place to find a turtle with strong armor and strong flesh. When taking the turtle, you need to wait for the night when the moon is full of stars, cover the turtle with a clean cloth, and hold it lightly. Don't startle him. After getting the turtle, put it in a quiet room, bathe it with clean water, and do not eat for three days, so that its abdomen is empty. Then, take the charcoal of the thousand-year-old spirit wood, burn it in a pottery furnace, wait for the charcoal to be red, place the turtle on it, cover it with thin tiles, and slowly roast it. During this period, you need to pay attention to the heat, and don't be too hasty, for fear of hurting its quality. Wait for the tortoise shell to bloom slightly, take it out and cool it. Then quench it with ice spring water, and repeat it three times, the nail is firm and strange.
The three-pronged base stele is the first material to be selected. The stele material should be taken from the huge rock in the deep mountains and old forests. The stone is fine and the texture is smooth. After picking the stone, it should be transported to an open place. Use ink lines to shape it, and if you want to form a three-pronged shape, each edge should be straight and of equal length. The craftsman chisels with an axe, and chisels according to the line. First chisel the outline, and then engrave the lines. When engraving, it is appropriate to use a sharp knife, and each knife The lines are either surrounded by clouds or galloping for auspicious beasts, all of which need to be lifelike. When the stele body is first formed, grind it with fine sand to make the surface as smooth as a mirror. Then, take cinnabar, realgar and other pigments, mix them evenly, apply them to the stele body, dry them in the sun, and infiltrate the moon dew. The color of the stele will last for a long time, and it has the ability to suppress evil spirits and pray for blessings.
The preparation of these two requires careful craftsmen and follow the ancient methods to become exquisite tools.
