1% 2C2-diethyl-4-chlorobenzonitrile, which is an organic compound. Its physical properties are as follows:
Under normal temperature and pressure, it is mostly white to light yellow crystalline powder. The texture is fine, and it is relatively stable in the air. It is not easy to undergo rapid qualitative change due to conventional environmental factors.
When it comes to the melting point, it is about 50-52 ° C. The characteristic of the melting point makes it change from solid to liquid at a specific temperature. This temperature range is relatively accurate and can be used as an important physical indicator for the identification of this substance.
In terms of boiling point, it is about 275 ° C. The boiling point reflects the temperature conditions required for the substance to change from liquid to gaseous state. Such a high boiling point indicates that it is difficult to vaporize and volatilize in a conventional heating environment.
In terms of solubility, its solubility in water is extremely low and almost insoluble. Due to the weak polarity of the molecular structure of the compound, it is difficult to form an effective interaction with water molecules. However, in organic solvents such as acetone, dichloromethane, and chloroform, it exhibits good solubility and can be miscible with these organic solvents in a certain proportion. This property is of great significance for its separation, purification, and reaction operations in organic synthesis and related chemical production processes. < Br >
The density is about 1.18 to 1.22 g/cm ³, and the density value determines its position distribution in the mixing system. In the operation links of material mixing and stratification involved in chemical production, density is a physical parameter that cannot be ignored.

The synthesis method of 1% 2C2-diene-4-alkynes is not specifically discussed in the ancient book "Tiangong Kaiwu", but combined with the wisdom of ancient chemical processes and related knowledge, it may be speculated from the following aspects.
One can be constructed by gradually splicing simple raw materials containing alkynyl groups and alkenyl groups. The basic raw materials containing carbon-carbon unsaturated bonds are obtained by the ancient method, or from natural materials first. For example, some vegetable oils can be specially treated to obtain alkenyl-containing components, while alkynes may be prepared from carbon-containing materials with incomplete carbonization and specific reagents. Such alkenes and alkynes can be interacted with each other under suitable conditions by using appropriate "medium" substances (similar to today's catalysts). < Br >
Both can be considered from the perspective of cyclization reaction. Select suitable chain-like polyunsaturated compounds, and under the action of high temperature and specific catalysts (ancient or with minerals, plant ashes, etc.), intracellular rearrangement and cyclization occur to form cyclic compounds containing 1% 2C2-diene-4-alkyne structure. If the raw material is chain-like, or needs to undergo multi-step modification, first make the unsaturated bond position and activity suitable, and then promote its cyclization.
All three can be modified by existing complex natural products. There are many organic compounds with complex structures in nature, or some contain fragments similar to the target structure. Ancient craftsmen used acid and alkali treatment, heating, light and other means to change its structure, causing specific parts to break bonds and form bonds, and convert it into 1% 2C2-diene-4-alkyne. However, this process requires in-depth understanding of the properties of natural materials and fine operation. Due to the complex structure of natural materials, it is easy to overreact and cause impure products.

1% 2C2-diene-4-naphthalene should be paid attention to in storage and transportation. These organic compounds are active and highly reactive, and easily react with other substances.
At the time of storage, the first environment is dry and low temperature. Because moisture and high temperature can easily promote decomposition or reaction and damage its quality, it should be placed in a cool, dry and well-ventilated place. Furthermore, it should be kept away from fire sources and oxidants. This compound is flammable, and in case of open flames, hot topics or strong oxidants, it may cause combustion or even explosion, endangering safety. At the same time, storage containers must also be carefully selected, preferably those that are resistant to corrosion and well sealed to prevent leakage and avoid reaction with the container material.
As for transportation, strict regulations and standards must be followed. Before transportation, it is necessary to properly pack to ensure that the product is stable to prevent vibration and collision from causing package damage. During transportation, temperature and humidity should be closely monitored to maintain suitable environmental conditions. In addition, transportation personnel need to be professionally trained to be familiar with the properties of this compound and emergency treatment methods. In case of emergencies, they can respond quickly and appropriately to ensure the safety of personnel and the environment.
All these precautions are to ensure the safety and stability of 1% 2C2-diene-4-naphthalene during storage and transportation, and must not be negligent.

Hearing your inquiry about the market price of 1,2-diethyl-4-chlorotoluene, I will investigate it carefully for you. However, the market price of this product often changes from time to time, and it is related to various reasons, such as the distance of origin, the urgency of supply and demand, and the quality of materials.
Recently in the market, the price is about [X] yuan to [X] yuan per catty. If the origin is close and the material is sufficient, the supply will exceed the demand, and the price will be lower; conversely, if the origin is far away and the material is thin, the demand will exceed the supply, and the price will be higher.
Furthermore, the merchants in the city are different, and the pricing is also different. Big merchants win by volume, and the price may be slightly lower; small merchants are limited by cost, and the price may be slightly higher. To get a firm price, you must go to the market in person, consult the merchants in detail, or check the listed price on the business platform before you can get it.
Also, the market is impermanent, and the rise and fall of prices cannot be predicted. If you are interested in trading, you should always pay attention to changes in market conditions in order to find the best policy.
