Under normal temperature and pressure, it is mostly colorless to light yellow liquid, with uniform and clear texture. This appearance is easy to intuitively identify, and in many chemical scenes, it can be preliminarily judged whether its state is normal.

Smell its smell, often emitting a special aromatic smell, but this smell is not simply pleasant and fragrant, or has a certain irritation. When handling this substance, do not ignore its potential irritation due to its aroma, so as not to cause damage to the respiratory tract.

As for the melting boiling point, the melting point is quite low, and it is liquid at room temperature; the boiling point is relatively high, about a certain temperature range (the specific value is subject to accurate measurement). This melting boiling point characteristic is of great significance in the process of separation, purification and storage. When heating and separating, the pure product can be obtained by distillation and other means according to the difference in boiling point; when storing, the ambient temperature should be taken into account to prevent it from vaporizing and escaping due to excessive temperature.

In terms of solubility, it shows good solubility in organic solvents such as ethanol and ether, and can dissolve with each other to form a uniform solution. However, the solubility in water is not good, and it can only be slightly soluble. This difference in solubility can be used in chemical synthesis, extraction and other operations to select suitable solvents to achieve effective separation and reaction. The density of

is slightly smaller than that of water. If mixed with water, it will float on the water surface. This density characteristic can be used as an important basis for judgment when it comes to the operation of separation of aqueous and organic phases, and it is convenient for subsequent processing through stratification phenomenon.

What are the synthesis methods of 1,2-dicyano-4-fluorobenzene?

There are many ways to synthesize 1% 2C2-diethylamino-4-chlorobenzene. Here are some common methods for your reference.

First, 4-chloroaniline can be started. 4-chloroaniline is salted with sulfuric acid, and then reacted with acetic anhydride at a suitable temperature and pressure to obtain an acetylated product. Next, the acetylated product is alkylated with halogenated ethane in an alkaline environment, such as an alcohol solution of potassium carbonate. After alkylation, hydrolysis with acid or base, and removal of acetyl groups, 1% 2C2-diethylamino-4-chlorobenzene can be obtained. The key to this path lies in the control of the conditions of each step of the reaction. Temperature, pH and the proportion of the reactants are all related to the yield and purity of the product.

Second, 4-chloroanisole is used as the raw material. First, it is aminated with ethylamine under high temperature and pressure under the help of a catalyst, such as a copper catalyst, to obtain 4-ethylamino anisole. Then, haloethane is alkylated again to obtain diethylamino anisole. Finally, the target product is demethylated with a suitable reagent, such as hydroiodic acid. This method requires attention to the activity and selectivity of the amination reaction, as well as the side reactions of the demethylation step.

Third, start with 4-chlorobenzaldehyde. Shilling it condensed with ethylamine to form an imine intermediate. This imine intermediate is reduced with a reducing agent such as sodium borohydride or lithium aluminum hydride to obtain 4-ethylaminobenzyl alcohol. Then, the hydroxyl group is converted into a chlorine atom with a halogenated reagent, such as thionyl chloride, and the alkylation reaction with halogenated ethane is carried out again, and the final product is 1% 2C2-diethylamino-4-chlorobenzene. In this approach, the condensation and reduction steps must be handled carefully to ensure the smooth progress of the reaction and the quality of the product.

Synthesis methods have advantages and disadvantages. It is necessary to make a careful choice according to many factors such as the availability of raw materials, cost considerations, difficulty of reaction and purity of the product. In this way, the goal can be achieved smoothly on the path of synthesis.

What are the precautions for storing and transporting 1,2-dicyano-4-fluorobenzene?

1% 2C2-diethylamino-4-hydroxyquinoline must be paid attention to during storage and transportation.

Its properties may be unstable and sensitive to environmental conditions. When storing, choose a dry, cool and well-ventilated place.
