Trisodium (3E)-5-[(4,6-Dichloro-1,3,5-Triazin-2-Yl)Amino]-4-Oxo-3-[2-(2-Sulfonatophenyl)Hydrazinylidene]-3,4-Dihydronaphthalene-2,7-Disulfonate

I don't know what the product you are talking about is, so it is difficult to determine its chemical structure. However, in order to know the chemical structure of a product, it is often necessary to study it with scientific methods.
In the ancient "Tiangong Kaiwu", although there is no precision instrument to analyze the chemical structure of today, the system of describing various things also contains insight into the properties of substances. To understand the chemical structure of a product, today's method relies more on experiments.
First, you can obtain pure things from complex mixtures through separation and purification. Such as ancient alchemy and winemaking, it also means separation and purification to obtain the required things. Later, use spectroscopy, chromatography and other instruments to analyze. Spectroscopy, such as infrared spectroscopy, can show the functional groups in the molecule; nuclear magnetic resonance spectroscopy, can clarify the environment and connection of hydrogen, carbon and other atoms in the molecule. Chromatography can be divided into each component of the mixture to measure its content.
If the product is an organic compound, its chemical structure is often connected by covalent bonds of carbon, hydrogen and other heteroatoms. Carbon has tetravalent, can be chained and cyclic, and can be combined with hydrogen, oxygen, nitrogen and other atoms to form a variety of structures. Such as alcohols, containing hydroxyl functional groups; alters, with aldehyde groups. Inorganic products have different structures, or are ionic crystals, with anions and cations combined by ionic bonds; or are atomic crystals, with three-dimensional networks formed by covalent bonds between atoms.
The most important thing is to determine the chemical structure of the product according to the method of scientific experiment and analysis. Although "Tiangong Kaiwu" has wisdom, today's technology makes the structure analysis more accurate and efficient.

The main uses of this product, in general, can be described from the following ends.
First, in terms of production and labor, it has the power to help. Such as the equipment in "Tiangong Kaiwu", it is widely used in agriculture, craftsmanship, etc. In terms of farming, products such as waterwheels can divert water from rivers to irrigate fields, so that rice and sorghum can grow and will not be abused by drought. When craftsmen are working, sawing and planing can be used to fine-tune the wood, making it a material for pillars, laying the foundation for the construction of palaces and boats, greatly improving the efficiency of labor and reducing the consumption of manpower.
Second, it is very convenient for daily use in daily life. Such as ceramic utensils, or for eating and drinking utensils, or for storage. The soup is not leaked, and the grain is not rotten, so that the people can eat and live in a stable and orderly manner. There are also fabrics from the loom, which can be cut into clothes, cover the body to keep out the cold, and show etiquette. People stop in the world, so they have dignity and dignity, and the quality of life can also be improved.
Third, in the field of military weapons, it is of great significance. Products such as bows and crossbows are powerful weapons for defeating the enemy on the battlefield. Long-range firing of strong crossbows can frustrate the enemy's sharpness and disrupt its position when they are not close. The swords are incomparably sharp. When fighting in close combat, they can protect the safety of soldiers, help the army to strengthen the battlefield, defend the peace of the home and the country, and protect the lives of the people.
Fourth, it has also contributed to the field of cultural inheritance. Pen, ink, paper, inkstone and other objects are the means for literati and ink writers to record their thoughts and inherit culture. Pen can write splendid articles, inkstone can grind out the fragrance of ink and calligraphy, paper carries the wisdom of the ages, and ink retains the glory of the past. Countless classic works, calligraphy and painting treasures have been passed down to future generations, making the Chinese civilization continue and shine.

There are the following precautions in the use of this utensil:
First, check its texture. The material of this utensil may be divided into advantages and disadvantages. When using it, be sure to check the texture carefully. If the material is not good, or it is not durable, it is afraid of sudden damage during use, causing accidents. If it is a wooden utensil, it is necessary to check whether its texture is dense and whether there are signs of moth-eaten; if it is a metal utensil, check it for trachoma, rust, etc.
Second, clarify its usage. Each utensil has its own specific usage. If it is used improperly, it will not only be difficult to do its best, but also anti-vulnerable utensil. For example, if it is a mechanism, you should be familiar with the method of opening and closing the mechanism, step by step, and do not use force rashly. If there is a sequence of operation steps, it must be done in sequence, and it must not be reversed and confused.
Third, keep it in good condition. When using, take care to avoid collisions and falls. The utensils have been made to condense the blood of the craftsman. If they are accidentally damaged, it is a pity. If you need to move the utensils, lift them lightly and do not make them collide violently with other objects. If it is fragile, you should pay special attention.
Fourth, add maintenance from time to time. After the utensils are used, they need to be maintained in a timely manner to prolong their life. If metal products need to be prevented from rusting, they can be wiped with an oil cloth; wooden utensils need to be moisture-proof and insect-proof, and can be placed in a dry and ventilated place. Check the utensils regularly. If there is any small damage, repair them in time to avoid minor illness and cause the utensils to be unusable.
Fifth, adapt to its environment. Different utensils have different requirements for the use environment. Such as paper utensils, do not place them in a humid place, otherwise they are prone to mildew and rot; some utensils are sensitive to temperature, and overcooling and overheating may affect their performance and lifespan. Therefore, when using, make sure to keep the utensils in a suitable environment.

The physical properties of this product are related to the material, properties and functions. According to the text of "Tiangong Kaiwu", it is as follows:
The material of this product is either the genus of gold stone, or the material of grass and wood, or taken from leather, silk and linen. If it is gold stone, its quality is strong and dense, it has the feeling of falling, it is rigid in nature, not afraid of wear and tear, and it is resistant to water and fire. Such as hardware, it can be molten and formed in case of fire, and it will not be damaged for a long time if it is used for utensils. If it is made of grass and wood, it is light and tough, with different textures and density. It often has a natural fragrance or a simple atmosphere, but it is afraid of water and fire. When dry, it is easy to crack, and when wet, it is perishable. It needs to be properly handled, such as paulownia and nanmu. It can be used to make utensils and beams. Leather is soft and elastic, wear-resistant and cold-proof. It is taken from animal skins. After tanning, it can be used to make clothes and boots. However, it is also afraid of moisture. If it is wet for a long time, it will be moldy and rotten. Silk and linen are soft and slender, silk is shiny, and creamy to the touch. Hemp is simple. Both are breathable and sweat-absorbing. It is suitable for clothing, but its strength is inferior to gold and stone, and it
Its properties, either solid, with a certain shape, or liquid, can change with the shape of the utensil. Solid state, there are regular shapes, such as square, circle, edge, etc., easy to combine and build, as the foundation of construction and utensils. Liquid state, flowing and inhabitable, can penetrate and moisturize, and is indispensable in certain processes, such as dyeing and watering.
As for function, it varies depending on the use. Or for daily use, it can help people eat and live, such as pots and kettles for cooking, tables and chairs for sitting and lying; or for production, to help farmers, industry and commerce, such as ploughing arable land, looms to weave silk; it can also add beauty to decorative objects, such as pearl jade, carving, showing exquisite art. This is the essence of the physical properties of the product, which is related to people's livelihood and all industries, and cannot be ignored.

The method of making this product is the key to the inheritance of skills and the wisdom of creation.
Guanfu's "Tiangong Kaiwu", in which all kinds of crafts are discussed, are described in detail. If you want to know the method of making this product, you should follow the "Tiangong Kaiwu", first understand its materials, and then study the craftsmanship.
At the end of the selection of materials, you must choose excellent things. For example, "Tiangong Kaiwu" says that "all things are made, material is the foundation", and high-quality materials are the foundation of good products. The materials required for this product, either from mountains and rivers, or from ore and pottery smelting, need to be carefully screened, and their texture, color, and brittleness should be inspected to ensure that there are no defects.
As for the art of blending, the steps are complicated and delicate. At the beginning, the materials need to be rectified, or chopped, or washed, or calcined, so that they can be disciplined. Then the clever skills are applied, or fused, or woven, or carved. During this time, the control of the heat and the control of the strength are all about success or failure. For example, when casting a tool, the fire is fierce, the material is scattered, and the fire is not strong. Only when the fire is moderate can a good product be cast. When weaving, the interweaving of latitude and longitude, and the arrangement of density, all depend on the craftsman's heart and hand to correspond, so that they can form a fine shape.
Furthermore, in the process of blending, it is also necessary to pay attention to cooperation. " "Tiangong Kaiwu" also talks about the need for everyone to work together, each performing their own duties and complementing each other. Such as an iron smelting workshop, there are masters of furnaces, blasters, and forgers, and everyone works together to get good iron. The combination of this product must also be coordinated by all workers in order to be successful.
In short, the combination of this product requires the selection of excellent materials, skilled skills, and the collaboration of everyone. Follow the ancient methods and participate in today's ingenuity, so that you can make exquisite products.
