4-pyridinemethanamine, 2-bromo-

2-%E6%BA%B4-4-%E5%90%A1%E5%95%B6%E7%94%B2%E8%83%BA, its main chemical properties are as follows:
This substance is flammable, and it is easy to catch fire and burn in the environment of open flame and hot topic. When burned, products such as carbon dioxide and water are formed. This characteristic is derived from its carbon, hydrogen and other elements, and follows the general principle of combustion of organic compounds.
2-%E6%BA%B4-4-%E5%90%A1%E5%95%B6%E7%94%B2%E8%83%BA can also oxidize with oxygen. Even if there is no open flame, under suitable conditions, long-term contact with oxygen in the air will slowly oxidize, resulting in changes in its own properties and appearance, such as darkening of color.
It can also undergo substitution reactions. Some atoms or atomic groups in its molecular structure can be replaced by other atoms or atomic groups. For example, under specific conditions and the action of reagents, its hydrogen atoms can be replaced by halogen atoms to form halogenated derivatives.
In addition, 2-%E6%BA%B4-4-%E5%90%A1%E5%95%B6%E7%94%B2%E8%83%BA can participate in the addition reaction. In case of substances containing unsaturated bonds, under suitable catalyst and reaction conditions, additions can occur, making unsaturated bonds become saturated bonds, so that the molecular structure can be changed, which in turn affects its physical and chemical properties.
Because it is an organic compound, it is soluble to some organic solutes. It can be used as a solvent to dissolve some organic substances that are insoluble in water. Using the principle of similarity compatibility, it can be mixed and dissolved with organic compounds with similar structures and properties.

Dioxo-tetrahydroxylic acid, that is, oxidized ($H_ {2} O_ {2} $), is often synthesized.
One of the methods is the anthraquinone method. This method is mediated by anthraquinone derivatives. In the suitable solution, anthraquinone is first catalyzed and added to the chemical phase of anthraquinone. However, anthraquinone is oxidized and reversed, and anthraquinone is returned to form oxidation. In this process, anthraquinone can be used in a follow-up manner, which has high efficiency, low cost, and small environmental impact.
Its second method of solving sulfuric acid is commonly used. In the solution of sulfuric acid or sulfuric acid in an aqueous solution, in the solution tank, the reaction of the reaction is generated, and the sulfuric acid is oxidized to produce the sulfuric acid. In this case, the hydrolysis of the sulfuric acid can be obtained. This method was widely used in the early days, but the energy consumption is high, and the requirements of the gas are also high, so the alternative method is replaced.
The third self-oxidation method. In the presence of some chemical compounds, the oxygen in the air is reversed to form the oxide, and decomposed to obtain the oxide. This method is harmonious, and the oxygen-rich source in the air can be used, which has a certain development prospect.
There is also a direct synthesis method, which directly combines the oxygen and oxygen under the action of catalysis to generate the oxide. This path is the most ideal, with high atomic utilization rate and a lot of side effects. However, its efficiency is large, and the research and development of catalysis is very important. At present, it is still in the research and exploration stage, and strive to break through the model of engineering.

"Tiangong Kaiwu" says: "Dicyanotetramine, the functions involved in formonitrile, are widely used in various fields."
Fudicyanotetramine is an important raw material in the chemical industry. Based on it, a variety of fine chemicals can be produced. For example, synthetic resins, which are indispensable for industrial manufacturing. Synthetic resins have excellent properties, or are tough and wear-resistant, or insulating and heat-insulating, and are widely used in machinery manufacturing, electronic equipment and other industries. Dicyanotetramine participates in it, helping to improve the performance of resins, so that it can better adapt to different needs.
In the field of medicine, it also has its function. In the process of pharmaceutical synthesis, dicyanotetramine is often a key intermediate. Through delicate chemical reactions, it can be converted into pharmaceutical ingredients with specific curative effects. For example, in the preparation of some antibacterial and anti-inflammatory drugs, dicyanotetramine plays an important role and contributes to human health.
Furthermore, in the field of agriculture, it can also be seen. In the development of some chemical fertilizers, dicyanotetramine is used. Due to its characteristics, the nutrient release rate of fertilizers can be adjusted. In this way, crops can absorb nutrients more efficiently, which not only improves the yield of crops, but also ensures their quality. It is a good aid for agricultural production.
Foronitrile is closely related to dicyanotetramine. Foronitrile plays a significant role in the field of organic synthesis. In the synthesis of many complex organic compounds, formonitrile is the starting material or an important reaction reagent. Such as synthesizing special fragrances and dyes, formonitrile can endow fragrances with unique fragrance and dyes with brilliant color through a series of reactions, satisfying people's pursuit of quality of life and aesthetics. At the same time, in the field of material surface treatment, formonitrile also plays a role in improving the surface properties of materials, making them more durable and beautiful.

Dideuterium is the armor of tetratritium, and its physical properties are unique.
Dideuterium, deuterium is an isotope of hydrogen, and the nucleus contains one proton and one neutron. Dideuterium is polymerized, and its mass is heavier than that of ordinary hydrogen molecules. Under normal temperature and pressure, dideuterium is a colorless and odorless gas, similar to ordinary hydrogen, but due to its mass difference, the diffusion rate is slightly slower. Its boiling point and melting point are also slightly higher than that of ordinary hydrogen, which is affected by the mass due to the intermolecular force. And the chemical activity of dideuterium is similar to that of ordinary hydrogen, but in some chemical reactions, the rate may be different, which is caused by the "isotope effect".
As for tritium, tritium is also an isotope of hydrogen, and the nucleus contains one proton and two neutrons. Tetratium is extremely rare and radioactive, with a half-life of about 12.43 years. When tritium decays, beta particles are released and converted into helium-3. Due to its radioactivity, tetratium is rare in nature and relies heavily on artificial preparation. Tetratium gas is also colorless and odorless, but because of its radioactivity, it is potentially harmful to organisms and the environment, and it needs to be strictly protected during operation. Its physical properties are not only affected by mass, but also significantly changed by radioactivity.
When dideuterium and tetratium form an armor-like structure, this structure has both characteristics. The increase in mass increases the overall density, and the radioactivity of tetratium gives the structure a special radiation field. Its thermal properties are changed due to the interaction of dideuterium and tetratium, and its heat transfer is very different from that of ordinary hydrogen compounds. And because of its radioactivity, optical properties or unique absorption and emission spectra, it provides a new perspective for the study of material structure and interaction.

Looking at the city today, it is very difficult to determine the price of the two-stemmed rhizome and the four-stemmed rhizome. The price of the market is not static, but is mostly influenced by various reasons.
The price of the husband's medicinal materials depends first on the production. If the origin is abundant and the goods are accumulated in the city, the price may level off; if the origin is poor and the supply is few, there are many applicants and few suppliers, and the price will rise.
Secondly, the weather also has a great impact. When the epidemic is rampant, there are many people who need all kinds of medicinal materials, such as rhizome and rhizome, or used as medicine to treat diseases, and their prices will rise; if there is no disturbance of the epidemic, there are few people who need it, and the price will not be high.
Furthermore, the labor of harvesting is also related to the price. The hardships of harvesting herbs, the coarse production, all cost manpower and material resources. If the harvesting is complicated, and the cost is much, the price will not be cheap; if the harvesting is easy and simple, and the cost is saved, the price may be low.
There is also a business camp. There are merchants competing for sales, and there are those who reduce prices for customers; if there is a monopoly of merchants, it is not uncommon to control the market and raise prices.
As for today, if the origin of the two-stemmed dragon and the four-stemmed beetle is abundant, there is no major epidemic, and the picking is convenient and the merchants compete in the market, the price is even, and it is easy for ordinary people to ask for it; if the land is disastrous, the epidemic is frequent, and the picking is difficult and the merchants have a monopoly, the price must be high, and the non-rich cannot get it. The price of the market is not fixed by constant rules, and only by observing the situation can we obtain its outline.
