"Tiangong Kaiwu" says: "All things in the world have their own uses, and they all depend on the ingenuity and skills of craftsmen to achieve their success." 2% 2C4-diethylaniline is small, but in the forest of industry, it is also an indispensable material. In the production of dyes, it is like a danqing hand, painting a colorful world; in the manufacture of medicine, it is like a clever medicine, helping the road to health; with the help of rubber, if the foundation is strong, it will stabilize the quality of the product. This all highlights its importance in various industrial uses. Although it is not visible in the appearance of the finished product, it is in the quality. It is indispensable. It is the subtle gear of industrial operation, silently driving the wheel of progress.

2% 2C4-diethylaniline is an organic compound. It has many physical properties.
Looking at its properties, it is a colorless to light yellow oily liquid at room temperature, which is intuitively visible. Smell it, it has a special smell, which may help to identify it in actual scenes.
When it comes to the melting point, the melting point is about -38 ° C, and the boiling point is between 216 and 218 ° C. Such melting boiling point characteristics have a great influence on the maintenance and transformation of its state under different temperature environments. At low temperature, it may be easy to solidify; at high temperature, it is easy to vaporize.
The density is about 0.93 g/cm ³, which is slightly lighter than water. If mixed with water, it may float on the water surface.
In terms of solubility, it is slightly soluble in water, but soluble in organic solvents such as ethanol and ether. This difference in solubility is of great significance in the separation, purification and creation of the reaction environment.
In addition, 2% 2C4-diethylaniline is volatile, and its molecules may escape from the surrounding environment in the air. And because it is an organic compound, flammable, exposed to open flames, hot topics, etc., or cause combustion, special attention should be paid to fire safety when using and storing.

There are many methods for synthesizing 2% 2C4-diethylnaphthalene, each with its own strengths.
First, naphthalene and halogenated ethane are used as raw materials, catalyzed by Lewis acid, after Fu-g alkylation reaction. The raw materials of this method are easy to obtain, but the reaction conditions are relatively harsh, and it needs to be carried out in an anhydrous and anaerobic environment. Lewis acid is highly corrosive, and the post-treatment is complicated. The product selectivity also needs to be refined. The reaction is roughly as follows: When naphthalene encounters halogenated ethane, under the catalysis of Lewis acid such as aluminum trichloride, the alkyl of halogenated ethane replaces the hydrogen on the naphthalene ring to generate 2% 2C4-diethylnaphthalene.
Second, 2-ethylnaphthalene is used as the starting material and then alkylated with halogenated ethane. This path can improve the selectivity of the product, but the cost of 2-ethylnaphthalene is quite high, and the selective regulation of the secondary alkylation reaction is challenging, so the catalyst and reaction conditions need to be carefully screened. During the reaction, 2-ethylnaphthalene reacts with halogenated ethane under the action of a specific catalyst, and ethyl further replaces the hydrogen at a specific position on the naphthalene ring to obtain the target product.
Third, using naphthalene and ethylene as raw materials, under the catalysis of acidic catalysts, it is synthesized by alkylation reaction. Ethylene is cheap and easy to obtain, which is a major advantage. However, the reaction requires high temperature and pressure, which requires very high equipment, and the product separation and purification are not easy. Naphthalene and ethylene are catalyzed by acidic catalysts such as solid acids, the double bond of ethylene is opened, combined with the naphthalene ring, ethyl is introduced, and 2% 2C4-diethylnaphthalene is formed.
Fourth, the coupling reaction catalyzed by transition metals is used. This method has good selectivity and atomic economy, but the transition metal catalyst is expensive, the reaction conditions are precise, and large-scale application is limited. For example, through specific transition metal catalysts, the coupling reaction of halides containing naphthalenes and borate esters containing ethyl groups occurs to generate 2% 2C4-diethylnaphthalene.

When storing and transporting 2% 2C4-diethylnaphthalene, it is essential to pay attention to all kinds of things.
When storing, choose the first environment. It should be placed in a cool, ventilated and dry place, away from fire and heat sources. Because 2% 2C4-diethylnaphthalene encounters open flames, hot topics or risks that can cause combustion, endangering the safety of the surrounding area. And the temperature between the warehouses should be controlled within the appropriate range. If the temperature is too high or too low, it may affect its chemical stability.
Furthermore, the packaging must be strict. It should be ensured that the packaging is intact to prevent material leakage. If the package is damaged, not only the material or cause loss, but also the volatile gas or cause pollution to the surrounding air, and if the leaked material comes into contact with the human body, or causes damage to the skin, respiratory tract and other parts.
As for transportation, there are also multiple points of attention. The transportation vehicle must be equipped with the corresponding variety and quantity of fire equipment and leakage emergency treatment equipment. During driving, drivers should drive carefully and avoid violent operations such as sudden braking and sharp turns to prevent package collision damage.
When transporting, do not mix with oxidants, acids, etc. This is because 2% 2C4-diethylnaphthalene may react violently with such substances, causing serious accidents such as explosions. During transportation, it should also be protected from exposure to the sun, rain, and high temperature. Summer transportation, especially in the cool hours of the morning and evening, to avoid driving in the high temperature at noon.
The escort personnel must also be dedicated to their duties and closely monitor the whole transportation process. Once any abnormalities are detected, such as packaging leaks, abnormal odors, etc., effective measures should be taken immediately to ensure the safety of the transportation process. In this way, 2% 2C4-diethylnaphthalene must be properly stored and transported to avoid all risks.

The market price range of 2% 2C4-diethylaniline varies depending on a variety of factors. The price of this product is often determined by the cost of raw materials, production process, market supply and demand, and quality specifications.
Generally speaking, under ordinary industrial-grade quality, the price is roughly between [X1] yuan and [X2] yuan per ton. If the quality requirements are high purity, used in specific fields such as fine chemicals and pharmaceuticals, the price will increase significantly, reaching [X3] yuan to [X4] yuan per ton.
The cost of raw materials has a significant impact on its price. If the price of basic chemical raw materials required to produce 2% 2C4-diethylaniline rises, such as the price of key raw materials such as benzene and ethanol, it will lead to an increase in production costs, which in turn will drive up the price of 2% 2C4-diethylaniline.
Production processes also have an impact. If advanced and efficient processes are adopted, although product quality and output can be improved, the price of products may be higher due to high equipment investment and technology research and development costs. On the contrary, although the cost of traditional processes is low, the product quality or stability is not good, and the price will also vary.
Market supply and demand conditions are even more critical factors. When the market demand for 2% 2C4-diethylaniline is strong and the supply is relatively insufficient, the price tends to rise; if the market demand is weak and the supply is excessive, the price may fall.
It should be noted that the above price range is only a rough estimate, the actual price will fluctuate with market changes, and the prices given by different regions and different suppliers may also vary. For the exact price, you need to consult the relevant chemical product supplier, or refer to the professional chemical market information platform.
