Pyridine, 2,3-dichloro-5-(trichloromethyl)-

The chemical properties of this product are also related to its essence and the rules of change. In ancient Chinese, it can be said:
Concept is a thing, and its chemistry is determined by the structure and interaction of its atoms and molecules. Or it is active, easy to combine with other things, just like metals, it often combines with oxygen and rusts, which is the change of oxidation; or it is stable, not easy to be moved by foreign things, such as inert gases, often alone and not disturbed by other things.
And its solubility is also one end of chemistry. Or it is easily soluble in water, such as salt in water, which melts instantaneously and is mixed together; or it is difficult to dissolve in water and dissolves in other agents, such as oil, which easily enters ethers, alcohols, etc. This is due to the comparison between its intermolecular force and the intermolecular force of the solvent.
In addition, thermal stability also belongs to its chemical properties. When heated, it may be stable and unchanged, such as gold and stone; or easily decomposed and changed, such as some compounds, which disperse into various components when heated.
It also has its acidity and alkalinity, and is also important. If it is acidic, it can be combined with the alkali phase to generate salt and water, such as vinegar and alkali; if it is alkaline, it is the opposite. This is all about the ions they dissociate in solution. Hydrogen ions are mostly acids, and hydroxide ions are mostly bases.
As for redox properties, it is also a characterization of chemical properties. Those with oxidation can take electrons from other things and make them oxidize; those with reductivity can give electrons to other things and oxidize themselves. This is a common phenomenon in various chemical reactions.
All of these are the chemical properties of the product, related to its state of existence and the reason for its change. In fact, those who study this thing and use it should understand it in detail.

The main uses of this product are as follows.
First, it can be used as a production aid. In workshops, this product can assist the operation of equipment, make the production process smoother, and improve the quantity and quality of output. For example, in the industry of smelting iron, with its delicate structure, it may make the blast more powerful, make the furnace temperature appropriate, and the melting of iron is more perfect. The iron produced is tough and sharp, which can add a lot of convenience to craftsmen when building weapons, agricultural tools, etc., making the utensils of extraordinary quality and more suitable for people's livelihood and warfare.
Second, it is related to the convenience of life. It is also useful in the homes of ordinary people. For example, when you are at home, with the help of the characteristics of this product, you can make it more convenient to get water, and use clever mechanisms to draw water from a distance to the courtyard for daily drinking; or in terms of grain storage, because of its special material or structure, it can keep grain for a long time without rot, ensure a family's livelihood, and add stability to people's lives.
Third, above war, it can be used as a weapon for armaments. Its clever design or powerful functions can turn the tide of war on the battlefield. For example, during a siege, the equipment made of it can make the city wall's defense strong and broken, opening up a way for your own army to advance; when defending, it can also be used as a strong and powerful barrier to resist enemy attacks, protect the city and the safety of soldiers, and become an indispensable help for soldiers.
Fourth, in terms of transportation, it also contributes. If it is integrated into vehicles such as vehicles and ships, its performance may be improved. It makes the boat travel more brisk on the water, and it can achieve twice the result with half the effort by going down or upstream; it makes the car travel more smoothly on land, and the cargo transportation can cross mountains and rivers and obstacles, and travel unimpeded, promoting the circulation of materials and commerce in various places.

When an artifact is being made, it is essential to pay attention to all kinds of things, which are related to the success or failure of the artifact.
The first choice of materials. Material is the foundation of the artifact, and the quality of the artifact is expected to be excellent. For example, when casting a sword, the choice of iron needs to be pure in texture, tough and suitable, in order to cast a sharp blade that is cut into iron like mud. If the material has flaws, even if it is handled by a craftsman, it is difficult to become a good product. Therefore, when choosing materials, we should carefully examine its nature and quality, and obtain excellent materials, so as to lay a solid foundation for the artifact.
The second is the application of skills. The skill of a craftsman is the key to the molding of the artifact. Exquisite skills can turn decay into magic, so that the beauty of the material can be fully demonstrated. For example, the work of carving jade requires ingenious conception and carving skills according to the shape, color and pattern of the jade material. The fluency of the lines and the accuracy of the shape all depend on the accumulated efforts of the craftsman. If there is a slight mistake, beautiful jade may also be reduced to ordinary products. And different utensils have their own unique technical requirements. The drawing of the billet, the firing of the kiln, and the tenon and mortise splicing of the woodworking all need to be well-versed and used by the craftsman.
Furthermore, the rules of the law cannot be ignored. The production of utensils has its own set of laws, from the size ratio to the process steps. Only by following the rules can we ensure the regularity, practicality and beauty of the utensils. Taking the construction of a house as an example, the thickness and spacing of beams and columns, the size and position of doors and windows must follow the laws of construction, otherwise the house is not only unsightly, but may endanger safety. Although the laws may sometimes be rigid, they are the guarantee for the stability of the quality of the utensils.
Again, attentiveness is indispensable. In the process of making utensils, the heart of the craftsman should be focused as one, and there should be no slack. Distraction is easy to make mistakes and affect the quality of utensils. If one mind is used twice, the lines may be skewed when carving, and the heat may be deviated when firing. Only by adhering to the heart of concentration can we see the true chapter in the subtleties and make the utensils exquisite.
The manufacture of utensils requires attention to many aspects such as materials, skills, laws, and concentration. All elements complement each other and are indispensable. Only by taking into account and making good use can we create excellent utensils.

There are some things today. Compared with those who are similar to others, what is their superior length and geometry? Let me tell you one by one.
The materials of these things are selected from the vast mountains and rivers, all of which are of the quality of heaven and earth. Compared with those who are similar to others, their materials are purer and their texture is stronger. For example, using wood as a material, the wood taken is all thousand-year-old wood, with fine texture, firm and not brittle. Compared with ordinary wood, jade is better than stubborn stone, which is more than double the difference. In terms of craftsmanship, craftsmen are skilled, meticulously crafted, and meticulous. Every process is poured into effort, which is comparable to other shoddy craftsmanship. Looking at its shape, the lines are smooth and natural, like clouds and flowing water; looking at its workmanship, the mortise and tenon fit seamlessly, and it fits tightly. Others are similar, or have flaws in shape, and omissions in work, which pales in comparison.
Furthermore, the use of this thing is even more wonderful. Its functions are comprehensive and can meet a variety of needs. Such as travel equipment, it is not only fast and stable, but also able to withstand wind and rain, cold and summer, and makes people comfortable and safe during long journeys. And others are similar, either fast but unstable, or stable but not fast, or difficult to withstand bad weather. Compared with functions, high and low judgment.
In terms of its durability, it has been honed over time, and it can still last for a long time. Because of its exquisite material and exquisite craftsmanship. On the other hand, those who are similar to others have not reached a few years, or damaged or damaged, and cannot be used again. The advantages of this thing are not only one end, but also the material, workmanship, use, and long-term, all of which are better than those who are similar to others. In fact, it is the best among things, and it is a rare and good product in the world.
