Disodium (3Z)-3-[2-(3,3'-Dimethoxy-4'-{(2Z)-2-[1-Oxo-6-(Phenylamino)-3-Sulfonatonaphthalen-2(1H)-Ylidene]Hydrazinyl}Biphenyl-4-Yl)Hydrazinylidene]-4-Oxo-3,4-Dihydronaphthalene-1-Sulfonate

The chemical structure characteristics of this product are related to the key to its internal composition and properties. Although Guanfu's "Tiangong Kaiwu" does not directly refer to this specific product, there is no lack of common principles in its discussion of various things, which can be used to explore this characteristic.
The chemical structure characteristics of all things lie first in the composition of their elements. The elements are combined in a specific ratio and way to have unique properties. For example, the five elements of gold, wood, water, fire, and earth belong to each other, and they are combined with each other to produce all kinds of things. The elements of the product are either common carbon, hydrogen, oxygen, nitrogen, or rare metals and non-metallic elements. The properties are very different if the ratio is slightly different.
is the form of chemical bonds. Covalent bonds, ionic bonds, metal bonds, etc., each have their own energy. Covalent bonds, atoms share electrons, which makes the structure stable; ionic bonds attract charges to form bonds, which have unique manifestations in the crystal structure; metal bonds make metals have good electrical and thermal conductivity. The shape of the chemical bond of this product determines its hardness, melting point, solubility and many other physical and chemical properties.
Furthermore, the spatial configuration of the molecule is also crucial. Like the fit of mortise and tenon, the parts of the molecule are arranged in a specific spatial arrangement, which affects their reactivity and optical properties. Different configurations such as linear, planar, and three-dimensional create different characteristics of the product.
Look at the crystal structure again. If it is a crystal, the type of lattice, unit cell parameters, etc., will affect its macroscopic properties. The orderly arrangement of crystals gives the product a regular shape and specific physical properties, while non-crystals show different characteristics in a disordered state.
The chemical structure characteristics of the product are actually the result of the interaction of elements, chemical bonds, spatial configuration, crystal structure and many other factors. Only by understanding this mystery can we achieve twice the result with half the effort in its preparation, application and other matters, and it is also the key to unlocking the endless treasures of the material world.

This product is mainly used in the following fields:
First, in the field of military conquest, it is very important. In the past, when marching and fighting, it was necessary to quickly transmit military information and dispatch troops. Such as the setting of beacon fire, in the border fortress, once the enemy invaders invade, they will immediately light the beacon fire, using fireworks as the signal, and instantly transmit the military information to the camps, so that the defenders can quickly know the enemy situation and deploy defenses in advance. This is the application of military early warning. For example, in large-scale operations, it is necessary to coordinate the forces of all parties, and transmit command orders through flags, drumsticks and other signals to ensure the coordinated operation of all armies. This is the application of military command and dispatch.
Second, in terms of transportation, it is also indispensable. In ancient times, post roads were vertical and horizontal, and post stations were dotted. The messenger quickly relays documents, goods, etc. between the post stations. This product is used to ensure the smooth traffic of the post road, such as setting up road signs to guide the direction and repairing road facilities to ensure passage. And in waterway transportation, facilities such as beacons can guide ships to sail safely and ensure the orderly water traffic.

Such various physical properties make this product shine in various uses, which is really a rare wonder.

"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty. The book describes in detail the methods of making many utensils. However, because the specific products are not known, the following is an example of common porcelain manufacturing, described in the style of ancient classical Chinese.
When making porcelain, the first choice is soil. It is necessary to choose delicate and pure kaolin, which is warm and moist, and is a good material for making porcelain. After taking the soil, it must be carefully washed to remove its sand and gravel impurities, so that it is uniform like milk.
Then practice the mud, put the washed soil in a stone trough, and pound it with a wooden pestle, repeatedly several times to make it dense. Then knead it with your hands, so that there are no bubbles in the mud, fine and smooth, and it can be used for later use.
The methods of forming the billet include drawing the billet, printing the billet, and making the billet. For drawing the billet, the mud is placed on the roulette wheel, pulled by hand, and rotated with the wheel to make the mud form a tool. This technique requires the skill and experience of a craftsman. The printing billet is formed by a mold, and the mud is filled into the mold, compacted and scraped flat. For the billet, when the billet is slightly dry, it is cut with a knife to make the tool shape regular and uniform in thickness.
When the billet is completed, it is glazed. The formula of glaze is different for each kiln, or natural minerals are taken, or grass ash is added. The methods of applying glaze include dipping glaze, shaking glaze, blowing glaze, etc. To dip the glaze, immerse the blank body in the glaze slurry; to swing the glaze, inject the glaze slurry into the blank, and turn the blank body to make the glaze even; to blow the glaze, use a bamboo tube or special tools to blow the glaze slurry on the blank, so that the glaze layer is light and uniform.
Finally enter the kiln for firing. The structure of the kiln is quite critical, and the control of the heat is particularly important. After ignition, it must be done step by step, first with a low fire and slow drying, to remove its moisture, then with a medium fire to heat up, so that the blank body is firm, and finally with a large fire, the glaze melts. During this period, the kiln worker must be on duty day and night to observe the fire, observe the heat, and add firewood to adjust the air at the right time to make the kiln temperature just right. After many days of firing, the porcelain is
The above method of porcelain manufacturing is only a rough outline, but in fact all the details are related to the quality of the utensils. It requires craftsmen to strive for excellence and pass it on from generation to generation to achieve exquisite art.

The Quality Standards of this product are as follows:
First, the material needs to be of the highest quality. Based on good materials, the best products are cast. The selected material should be solid in texture, like gold and stone, without the slightest brittleness and softness. And it is pure and flawless, and there are absolutely no impurities mixed in, so as not to damage its essence and damage its characteristics.
Second, the craftsmanship must be exquisite. From the beginning to the forming, every step needs to be carefully handled. All processes, such as carving, grinding, forging, etc., should follow the ancient techniques, and the techniques should be skillful and precise.
