2-Chlorobenzimidazole

2-% oxygen is used to make fire, and it is mainly used to push fire and force. The ancient "Heavenly Works" has this, and this is mostly used in firearms, and the effect is most important.
The benefits of equipment are greater than firearms. And the ability and ability of firearms to fire and burn are due to this 2-% oxygen fire. With its ignition, it can be used quickly to generate power, pills and other things, and pushed out at high speed.
At the intersection of the distance, the power of this fire can be used to prevent it. When the pill arrives, it destroys the solid, so that it can be prevented and resisted.
And in the battle of siege, this fire can help a lot. The city is high and thick, if you can attack it with the power of the force, you can overcome it. And 2-% oxygen can be used to attack the power of the siege equipment, so that the stone, firearms, etc., can be used to build the city. If the city is like a siege, you can take advantage of it, and the whole city can be built.

Furthermore, the water can be used to destroy the ship, and the firearms can be used on the ship. With 2-% oxygen, the fire and the force can be used to shoot pills, and the ship can be used. Make the boat break down, the soldiers fall into the water, and the master of the water can be controlled.
In general, 2-% oxygen generation is one of the most important factors in the application of military equipment, because of its ability to generate power, the core force of firearms, and various aspects of power, such as power, water, siege, and wilderness.

It is the subtle manifestation of nature's creation that is responsible for the rationality of things in 2-% helium. The essence of the universe is the foundation of things. Its quality is often seen in the heavens and the earth, and the color is stinky, and it can be observed by the eyes. When the flame is burning, it turns into water when it encounters oxygen. This is the wonder of transformation. In the environment of low and high temperatures, it may be possible to create a liquid, but it needs exquisite methods to control it.
Helium is also a big problem, and it is also stinky. The second is the second, but it will not burn or explode, and it will be safer. In cold places, helium can be liquid, and it has the property of superfluidity. The flow is not sticky, and it can penetrate micro-pores, such as in the realm of matter. This is a rare phenomenon in physical nature.
Both of them are different, and those that are radioactive are also radioactive. Its atomic parts hide great energy, which does not radiate, and can penetrate things and make things that shine. However, this radiation is also harmful, and it can affect the order of living things.
Helium is different, and its properties are different, and it is different in the creation of heaven and earth. Helium, the source of vitality, can be used to make things; Helium is used to fix the world, and it is safe in the world; Helium is used for its radiation energy. However, if it can be used well, it can be used as a weapon of scientific research to break the secrets of nature, solve the problems of creation, and lead the world to explore the problems of material nature.

What is the transformation property of 2-% helium?
2-% helium is a combination of strange elements. Its characteristics are unique, and it has both the activity and stability of helium, such as softness.






















Under specific conditions, it can not only develop its activity, but also generate novel compounds. It can also maintain a certain degree of certainty due to the shadow of helium, so as not to affect the intensity.
Its physical nature is also interesting. Or it has a special color and taste, and its melting and boiling properties are equal. Due to the joint action of helium, it is difficult for the two to exist. Under normal conditions, it may show a special aggregation, non-solid, non-liquid, and non-solid, and has some three characteristics. The chemical activity of
and 2-% helium can vary depending on environmental factors such as temperature, temperature, and catalysis. The appropriate degree of resistance may greatly increase its reaction activity, giving rise to enrichment and reaction; and the intervention of catalysis can also control its reaction rate and direction, making it change in a more orderly way. Therefore, the chemical properties of 2-% helium have opened up new fields, which holds the possibility of change.

To prepare di-cyanopyridine and thiazole, there are various methods for its synthesis.
One is to use the compound containing the structure of pyridine and thiazole as the starting material, and to introduce the cyanyl group through the nucleophilic substitution reaction. First, take the appropriate pyridine derivative, in the basic environment, meet with the halogenated cyanide, and the halogen atom is replaced by the cyanyl group to gradually construct the desired structure. This process requires precise temperature control and time control, and the proportion of the reactants is also strictly required. A slight difference in the pool will affect the yield.
The second can be achieved by cyclization reaction. Starting with a specific chain compound, the molecule needs to contain functional groups capable of constructing the pyridine ring and the thiazole ring. Under the action of a suitable catalyst, cyclization and condensation occur in the molecule. For example, a metal salt catalyst is used to adjust the pH and temperature of the reaction system, and promote the rearrangement and condensation of chemical bonds in the molecule to generate the target dicyanopyridine and thiazole. The key to this path lies in the selection of catalysts and the optimization of reaction conditions, so that the cyclization reaction can proceed smoothly and the occurrence of side reactions can be reduced.
Furthermore, it can also be combined through a multi-step reaction. Pyridine fragments and thiazole fragments are first synthesized separately. Each fragment is carefully designed and modified, and then connected by a coupling reaction, and then a cyano group is introduced. Although this method is complicated in steps, the control of the structure is more precise, and the synthesis of each fragment can be flexibly adjusted according to the characteristics of the desired product. However, the multi-step reaction also means higher cost and more complicated operation. Each step of the reaction needs to be strictly purified to prevent the accumulation of impurities from affecting the purity and yield of the final product.

In the process of storage, there are many things that need to be paid attention to.
First of all, in the process of storage, it must be dry, clean and well-connected. This system is easy to change in case of tide. If it is in a place where the tide is high, it may be damaged or damaged, and the efficiency is great. And it has a certain degree of resistance. Under high temperatures, it is easy to disperse, so it is not suitable. And it is isolated from the source of fire, because it may be flammable, once it is exposed to fire, it is afraid of huge damage.
Furthermore, if it is difficult, the package must be damaged. Keep it in a corrosion-resistant and dense container to prevent it from leaking. If it is outside, it is not effective, and may cause pollution to the surrounding environment, and even endanger the safety of humans and animals. On the way, also pay attention to the collision of earthquakes. If it is damaged or caused by severe shock, it will affect the quality of the product.
In addition, if it is stored or damaged, it must be divided into other chemical products. 2-% oxygen or some chemical and biological reactions, resulting in changes in the quality of the product, and even harmful substances.
Workers also need to be familiar with the safety information of the product. Operate well and prevent damage, such as gloves, masks, eyes, etc., to avoid contact with the skin and respiratory tract. If it is accidentally connected, it needs to be washed with a lot of water immediately, and the heavy one will be washed quickly.
Therefore, the storage of 2-% oxygen should not be lost, so as to ensure its safety and use.
