The methods of synthesis of aminobenzene are quite different. The ancient Fang family, in order to seek this medicine, tried to work hard, and now it is the king's way.
One method is to start with nitrobenzene. Nitrobenzene is quite stable and can be co-heated with iron and hydrochloric acid. In this reaction, iron is used as a reducing agent, and hydrochloric acid helps to make the nitro group of nitrobenzene gain electrons and gradually turn into an amino group. In this way, the nitrogen of the nitro group gradually decreases from a high price, and finally becomes an amino group. After the reaction is completed, the aminobenzene can be obtained by separation and purification by the usual method.
There is also a method of acylation based on aniline. First, aniline is mixed with an acylating agent such as acetic anhydride to obtain acetaniline. This acyl group masks the amino group of aniline to weaken its activity and prevent it from overreacting. Later, if you want to complex its amino group, use the method of acid and base to remove its acyl group to obtain aminobenzene. In this way, when synthesizing other substances, the amino group can be reacted according to human intention to avoid the change of heteroarbons.
Furthermore, start with halogenated benzene. Halogenated benzene coheats with ammonia and copper salts, and the halogen atom can be replaced by an amino group to obtain aminobenzene. The copper salt is a catalytic agent, and the halogen atom of halogenated benzene is easy to react with the amino group of ammonia. However, the activity of halogenated benzene is different, and the halogen atom is different, and the reaction is difficult and easy.
There is also a method of diazonium salt. The aniline is first formed into a diazonium salt, which is prepared from sodium nitrite and hydrochloric acid. The diazonium salt is active and can react with a reducing agent to make the diazonium group convert to hydrogen, and also obtain aminobenzene. Or the diazonium salt reacts with a nucleophilic reagent, introduces other groups, and then tries to obtain aminobenzene.
This number method has its own length and its own shortcoming. The method of choosing a square home must depend on the availability of raw materials, the level of cost, the difficulty of the reaction, and the purity of the product.

Today there are 3-question-4-aminopyridine, what is the market price of it?
The market of Guanfu City, the price of goods often depends on multiple ends. In 3-question-4-aminopyridine, the change in its price is primarily related to supply and demand. If the market is prosperous and the supply is scarce, the price will rise; on the contrary, if the supply exceeds the demand, the price will decline.
Furthermore, the difficulty of its production is also the key to the price. If its production requires exquisite skills, rare materials, and huge expenses, its price will rise. If it is easy to make and the cost is saved, the price will be close to the people. < Br >
There are various factors, such as political regulations and tax rates, which can also move the price. If taxes are strictly increased, the cost will rise and the price will rise; if taxes are relaxed and reduced, the price will rise or fall.
In today's world, the trade road is busy, and the price will change at any time. If you want to know the price of aminopyridine 3-question-4-aminopyridine, it is advisable to visit the cities and trading houses, or consult the elders in various industries, so that you can get a more accurate number. The city is unstable, and the price is irregular. It is necessary to observe it over time and measure it with emotion to understand the price.

The physical and chemical properties of 3-nitro-4-aminopyridine can be investigated. This compound is in a solid state and is relatively stable at room temperature. Looking at its color, it often appears white to light yellow, which is a sign of its appearance.
When it comes to solubility, its solubility in water is quite limited, but it has a certain solubility in some organic solvents, such as ethanol and acetone. This property is related to the polar groups in its molecular structure. There are both strongly polar groups such as nitro and amino groups in its molecule. The interaction between the two affects its solubility in different solvents.
As for the melting point, it has been determined that it is within a certain temperature range. This temperature value is an important indicator of its physical properties. The value of the melting point reflects the strength of the intermolecular forces. In this compound, the molecules are maintained by hydrogen bonds, van der Waals forces, etc., and the sum of these forces determines the melting point.
From the perspective of chemical properties, 3-nitro-4-aminopyridine has a certain reactivity. Amino is an electron-supplying group and nitro is an electron-withdrawing group. The two coexist on the same molecule, causing uneven distribution of molecular electron clouds, thus changing the electron cloud density of the pyridine ring. This change makes the compound easy to react with electrophilic reagents or nucleophiles, and can be used as an important intermediate in the field of organic synthesis to participate in many chemical reactions to build more complex organic molecular structures.

Third, tetraaminopyridine and tetraaminopyridine are used in the storage system. It is made by ancient methods and is explained below.
tetraaminopyridine is very sensitive to nature. It can be caused by light, moisture, and damp. Therefore, it is appropriate to avoid direct light, and to isolate fire and damp sources. Its capacity is also sealed to prevent the intrusion of moisture. It must not be combined with oxidation, acid, etc., because of its chemical properties, or the reaction of causing danger.
When it comes to the environment, it must be properly packaged according to the method. The material of the package has the ability to prevent vibration, collision, and can resist the shadow of the outside world. On the way, all those who work hard should be careful to avoid high and high-altitude environments, and there should be no severe bumps. If there is a need or poor situation on the way, it is more appropriate to pay more attention to ensure its safety.

People are also familiar with the properties and dangers of tetraaminopyridine, and it is appropriate to take urgent measures. In case of leakage and other things, do not panic, and follow the prescribed method to set it up quickly. Those who are separated first, forbidden to approach, and then collect leakage with dirty things should not be allowed to pollute the environment.
If there is no storage or tetraaminopyridine, they should be careful and follow the law to ensure its safety and the safety of people's environment.
