What is the chemical structure of 17- (2-iodoethyl) tridecane?
The book "Heavenly Works and Creation of Things" is also a strange book of ancient science and technology, but it does not describe the chemical structure of the thirty-seven dogs. I try to solve this confusion for you with what I know.
The thirty-seven dogs, or the common name of the ancient times, are not yet known. However, according to the theory of chemistry, the structure of a substance depends on the arrangement and combination of its atoms and molecules.
The analysis of the chemical structure of the husband, the identification of the first heavy element. Everything in the world is composed of various elements, such as hydrogen, oxygen, nitrogen, carbon, etc. Elements are the basis of matter, and their atoms have their own characteristics.
The second is the shape of molecules. Molecules are formed by the association of atoms according to specific rules. The combination, number and order of atoms all determine the properties of molecules. For example, water molecules are connected by dihydro-oxygen atoms with covalent bonds to form a V-shaped state, which determines many physical and chemical properties of water.
If there is a crystal structure, when the substance is in the solid state, the atoms or molecules are arranged according to the law and form a lattice shape. The rules of its arrangement also affect the properties of the substance, such as hardness, melting point, etc.
However, the thirty-seven dogs have no detailed reference, and it is difficult to determine its chemical structure. Or it is an organic body, with carbon chains as bones, and atoms such as hydrogen, oxygen, and nitrogen connected to form complex molecules; or it is an inorganic substance, with metals and non-metallic elements connected by ionic bonds, covalent bonds, etc.
To understand the chemical structure of the thirty-seven dogs, it is necessary to know in detail what it is, and use scientific methods, such as spectroscopy, diffraction and other techniques, to analyze its elemental composition and molecular structure. This is not detailed in ancient books, and it is difficult to judge it today with a few words.
What are the physical properties of 17- (2-iodoethyl) tridecane?
It is recorded in "Tiangong Kaiwu" that Panax notoginseng is a treasure among ginseng, and its physical properties are unique.

What are the synthesis methods of 17- (2-iodoethyl) tridecane?
"Tiangong Kaiwu" states that where a mirror is cast, gray sand is used for the mold, and tin and copper are used for the copper. If you want to make a mirror of thirty-seven taels, the copper is six points, and the tin is four points. According to this ratio, the mirror cast is white and lovely.
If you cast a mirror of thirty-three taels, there are two methods. First, the ratio of copper to tin is 6 to 4. For copper, sixty percent of thirty-three taels is nineteen taels and eight coins; for tin, forty percent of thirty-three taels is thirteen taels. According to this ratio of copper and tin, first melt the copper, wait for the liquid flow to be smooth, then add tin, stir it evenly, pour it into the gray sand mold that has been made, and cool it into shape. This is the usual method.
Second, the proportion can be fine-tuned. Due to different uses or preferences, if you want the mirror to be brighter, you can slightly increase the proportion of tin, such as the ratio of five taels of copper and four taels of tin. However, the increase in tin should not be too much. If it is too much, the mirror will be brittle and vulnerable. Or because the mirror needs to be slightly tough, the amount of tin can be slightly reduced. The combination of six taels of copper and three taels of tin can be used. In this way, although the light color is slightly inferior, the texture is firmer. When casting, the heat and stirring need to be just right. If the heat is too high, the metal will be lost. If the heat is not enough, the fusion will be poor. Uneven stirring also affects the quality of the mirror. The art of casting mirrors, the subtleties are all about success or
What are the precautions for storing and transporting 17- (2-iodoethyl) tridecane?
"Tiangong Kaiwu" has a saying: "Panax notoginseng is used for storage and transportation, so many people should pay attention." The husband of the panax notoginseng is cunning and good at hiding. When it is used for storage, it is not just for temporary fulfillment, but for long-term needs. Therefore, when storing, choose the place as necessary. You must have a secret place to prevent other beasts from peeping, and it should be dry and ventilated to prevent things from spoiling. For example, in the kuma of the mountain forest and in the stone cave, it is the best choice.
As for transportation, there is also attention to it. Panax notoginseng is small in size and limited in strength. Therefore, the things you carry must be done according to your ability, and you must not be greedy and tired. And the action is agile, and the choice of path is about success or failure. It is advisable to avoid the common path of humans and beasts, and choose a secluded path before you can travel unimpeded. If you encounter obstacles, or detours, or temporary hiding, just wait for the time to move.
Furthermore, the change of seasons has a great impact on storage and transportation. In autumn and winter, things are abundant and cold is approaching, so Panax notoginseng should be stored quickly to prepare for the shortage of cold winters. At this time, transportation must also be stepped up, and it is easy to move while things are not frozen. In spring and summer, although things are gradually growing, there is a lot of rain, so beware of leakage in the storage place, and avoid muddy roads when transporting, so as not to get stuck and difficult.
Also, among the same kind, there is also the possibility of cooperation. Or find a storage place together, or help transport heavy things, so that you can get twice the result with half the effort. However, it is also necessary to prevent the same kind of embezzlement, so the division of labor must be clear and mutual trust is the basis.
Panax notoginseng is essential for storage and transportation, site selection, capacity, timeliness, and cooperation, etc., in order to survive and multiply, and to gain a seat in the world.
