To prepare pyridine, 2-hydrazine, the method is as follows:
First take a suitable raw material, use pyridine as a base, and introduce a hydrazine group under specific reaction conditions. Pyridine derivatives are often reacted with hydrazine reagents. This reaction requires the selection of a suitable solvent to help the reactants dissolve and facilitate the reaction, such as ethanol, dimethyl sulfoxide and the like.
During the reaction, the temperature control is very important. The initial temperature can be slowly increased, so that the reactants can be fully mixed and the reaction is initiated. Then, according to the reaction process and requirements, it is stable in a certain temperature range, or low temperature is required to control the reaction rate, or higher temperature is required to promote the complete reaction.
The catalyst is also indispensable, which can reduce the activation energy of the reaction and accelerate the reaction. Choose a suitable catalyst, either a metal salt or an organic base, depending on the reaction mechanism and characteristics.
After the reaction is completed, the product needs to go through the steps of separation and purification. Distillation can be used to separate impurities according to the boiling point of each substance to obtain a purer product. Column chromatography can also be used to separate the product from impurities by means of fixed phase and mobile phase to achieve a high purity state. Through these steps, pyridine, 2-hydrazine can be obtained.

The physical properties of pyridine, 2-hydrazine, are as follows: This substance is mostly solid at room temperature, and its color state is white to light yellow crystalline powder. This is its apparent property. Looking at its smell, or it has a special taste, but this taste is unusual and analogous, so you need to smell it yourself.
When it comes to solubility, in common organic solvents, it is quite able to dissolve into alcohols, such as ethanol, It can be better miscible, just like the fusion of fish and water; in ether solvents, such as ether, it also has a certain degree of solubility, but it is not as good as alcohols. As for water, although it is not very soluble, it also has a little ability to dissolve, which is its state of being sparse with water. < Br >
Its melting point is a specific value. This value is one of the inherent characteristics of matter. It is just like the birth of a human being, and it is specific and difficult. However, the specific melting point needs to be determined by precise experiments to be sure. The boiling point is also an important physical property of its, reflecting the critical condition for its transformation from liquid to gaseous state. This value also needs to be obtained by rigorous experiments, which is related to its phase transition at different temperatures.
Density is an index for measuring its mass per unit volume. Compared with other substances, it has its own unique value. This value is related to its distribution and behavior in various systems, and is quite important in practical applications. Its stability to light and heat is also the key to physical properties. When exposed to light, or due to the action of light quanta, subtle changes occur; when heated, or when a certain temperature limit is reached, structural or property changes are triggered, which all need to be investigated in detail to clarify its stability in different environments.
