Pyridine, 2-bromo-6-methyl-3-nitro-

What are the chemical properties of this product? I will answer you with the classical Chinese body of "Tiangong Kaiwu".
Every human being has its own characteristics, and the chemical properties of this product are related to its essential characteristics. Looking at all things in the world, they are all composed of elements, each according to its own nature, either stable or variable, or affinity or sparsity.
This product is at room temperature, or in a stable state. In case of fire, there may be different responses. If it is flammable, it may emit strong light, or produce thick smoke, or have peculiar smell when burning, which is a sign of its combination with oxygen. The rate of combustion varies depending on the material, either rapidly or slowly.
As for water, there are also different changes. Or soluble, fused with water, into a uniform liquid; or insoluble, floating on water, or sinking on the bottom of water, or reacting with water, generating bubbles and heating, all due to its chemical structure.
And if it encounters acid and alkali, the reaction is more complicated. Acids are corrosive, and alkalis also have their own unique properties. Encounters with them, or precipitation, or gas, or discoloration, are all manifestations of chemical properties.
Furthermore, its oxidation is also the key. In the air, it circulates with time, or is gradually oxidized, the surface changes color, and the texture becomes brittle, which is due to the slow response to the oxygen in the air.
All chemical properties are determined by the constituent elements and molecular structure of the product. If you want to know the details, you must use scientific methods and rigorous investigation to clarify its properties, make good use of it, and avoid its harm and promote its benefits.

This product is widely used and has applications in many fields.
In the field of agricultural mulberry, it can help cultivators sow, irrigate, and cultivate. In the past, farmers relied on human and animal strength, and their labor was hard and inefficient. Today, this product can replace human labor, so that the sowing is uniform, the irrigation is timely, the cultivation is deep, and the fields are quite productive. If sowing in spring, it can accurately distribute seeds, so as not to lose density; irrigation in hot summer can lead canal water to dry places and relieve thirst of seedlings; harvesting in autumn can also help harvest, save man-hours, and enrich farmers' warehouses.
In the world of construction, it shows its skills. It is indispensable to build palaces, pavilions, roads and bridges. It can carry boulders and trees, and lift them to where they are needed, so that the construction can be twice the result with half the effort. In the past, it was difficult to carry bricks and stones when building the Great Wall. If there is this product, it will definitely speed up the progress of the project and reduce the loss of civilian power. Today's high-rise buildings also rely on it to lift building materials, so that high-rise buildings can rise from the ground, and the city style is changing with each passing day.
In military affairs, it is also very useful. It can carry weapons, grain and grass, and ensure the supply of military supplies during the march. In wartime, it can build fortifications, build defensive barriers, and enhance the defense of the army. Like the ancient battlefield, it is not easy to transport food and grass. This product can ensure the timely delivery of food and grass, so that soldiers have no worries and fight bravely to kill the enemy.
In the way of commerce and trade, it is conducive to the At the docks and post stations, the goods are loaded and unloaded frequently. This product can be loaded and unloaded quickly and improve the efficiency of business circulation. North-south cargo exchanges rely on their transshipment to make the market rich in materials, communicate with each other, and promote business prosperity.

There are many preparation methods of this product, and the following are described in detail by Jun.
First, the ancient method of grinding. Select high-quality raw materials, use stone grinding and other utensils, and grind them slowly. This process pays attention to mental effort and skills, and slowly pushes and moves slowly to make the raw materials delicate and uniform. In the past, craftsmen in quiet workshops used their wrists to grind the raw materials into a delicate paste to retain their authenticity. Although time-consuming and laborious, the quality obtained is high, and it is mostly used by dignitaries.
Second, the method of distillation and extraction. Use special distillation utensils, place the raw materials in them, and roast them with fire to make the essence of the raw materials into steam and rise, and then collect them by condensation. This process requires controlling the heat and temperature. If the heat is too fierce, the essence will dissipate, and if the heat is insufficient, the extraction will be incomplete. This method can obtain the pure essence of the raw material, and is often used in the preparation of products that pursue high purity.
Third, the recipe for fermentation and aging. Take the raw material and place it in a suitable environment to make it ferment naturally. During this period, pay attention to the temperature, humidity and ventilation conditions to create an environment conducive to the reproduction of microorganisms. After the fermentation is completed, it will be aged for a long time to make the product have a more mellow texture and unique flavor. In ancient times, there was a cellaring place, which was kept in a constant temperature and humidity place underground, hidden for years, so that the product could last for a long time.
Fourth, the technique of mixing and blending. According to the required characteristics of the product, select several different raw materials and mix them in precise proportions. The key lies in the familiarity of the characteristics of each raw material, and if it is properly blended, it will complement each other and the product quality will be extraordinary. In the past, the imperial palace was often precisely blended according to the secret recipe, resulting in a unique product.

There are many things today, and compared with other kinds of small things, what is the advantage of them?
A spectator is a thing, and the first thing is its material. Made of good materials, the quality is strong and beautiful. As the "Tiangong Kaiwu" says: "Where a mirror is cast, the mold is made of gray sand, and the copper is made of tin and..." The material of a mirror is related to the quality of the mirror. The same is true for this thing. The material is well-selected. Compared with other kinds of small things, the material is stronger and more beautiful. If you use ordinary materials, the quality is weak and vulnerable. Here you see the advantages of the material.
Second time on its work. The work of the things is exquisite and meticulous. Craftsmen make it, dedicated and meticulous. " "Tiangong Kaiwu" also says: "Where a bow is made, the bamboo should be cut first as a dry job,..." The work of making a bow is fine step by step. The production of things is also in this way, the craftsmanship is exquisite, and every part is carefully crafted. Other kinds of things are rough and sparse, and the shape is not refined, but the things are unique with exquisite workmanship.
Furthermore, the effect of the things is good. If you use them, you can see their function, and they can meet people's needs. Taking farming tools as an example, "Tiangong Kaiwu" contains tools such as Leiji, which help farmers. The fields where things are used can also be efficient. Compared with other kinds of small things, or those with insufficient efficiency, the things can get twice the result with half the effort, saving time and effort for the user. < Br >
And its shape is also beautiful and elegant. Ancient man-made utensils, the beauty of heavy shape, such as the solemnity of Ding Yi, the warmth of jade. The beauty of the shape of the object is both practical and ornamental. Other kinds of things are small, or the shape is clumsy but not rhyme, in contrast, the beauty of the shape of the object is highlighted.
In summary, the object is better than other kinds of things, with excellent material, workmanship, efficiency and beauty, all of which are better than others.
