1% 2C4-bis (triethoxysilyl) -2-cyanobenzene is a kind of organosilicon compound. Its physical properties are quite special, let me describe them in detail for you.
First of all, under normal circumstances, this substance is mostly a colorless to light yellow transparent liquid, which is clear in appearance and has no impurities visible to the naked eye.
As for the melting point, it has been investigated by many parties and is about - [specific value] ℃. Under low temperature environment, it can maintain a liquid state, which shows the low melting point. The boiling point, at atmospheric pressure, is about [specific value] ℃, and the higher boiling point indicates that it needs to absorb more energy during the heating process to convert from liquid to gaseous state.
Furthermore, density is also one of its important physical properties. At [specific temperature] ℃, its density is about [specific value] g/cm ³, which reflects its mass per unit volume and is of great significance for considering its fluctuation and mixing characteristics in different media.
In terms of solubility, 1% 2C4-bis (triethoxysilyl) -2-cyanobenzene is soluble in many organic solvents, such as toluene, xylene and other aromatic hydrocarbon solvents, and can also be soluble with ketone solvents such as acetone and butanone. However, in water, its solubility is poor, because the molecular structure of the compound has strong lipophilicity of groups such as siloxy, and although the cyano group has a certain polarity, it is not enough to dissolve well in water.
In addition, the volatility of this substance is relatively low, and its volatilization rate is relatively slow under normal ambient temperature and humidity conditions. This characteristic guarantees its stability during storage and use, and is not easy to be lost due to rapid volatilization.
From the above, the unique physical properties of 1% 2C4-bis (triethoxysilyl) -2-cyanobenzene have laid a solid foundation for its applications in materials science, organic synthesis, and many other fields.

The synthesis method of 1% 2C4-bis (triethoxysilyl) -2-cyanobenzene is not directly recorded in ancient books such as Tiangong Kaiwu. However, although the ancients did not directly describe this product, its chemical process concept may be used for reference. The following attempts to explore the ancient ideas.
If you want to make this product, you can consider the selection of raw materials and the reaction path. In terms of raw materials, triethoxysilyl related raw materials, although the ancient method does not have its pure product, silica is easy to obtain. Silica is calcined and reduced with carbon to obtain crude silicon. Crude silicon, ethanol and halides, in appropriate proportions, can be prepared or related precursors of triethoxysilyl can be prepared. The method is such as stone refining as iron, using carbon as a medium to change its form.
As for the cyanobenzene part, it can be started from benzene. In ancient times, benzene may have been distilled from coal tar. Although the purity is not good, it can be obtained through multiple fractionations. Benzene reacts with cyanide reagents, such as sodium cyanide (although there is no sodium cyanide in ancient times, cyanide-containing minerals may be used instead), under appropriate conditions, and cyanide groups can be introduced. This step requires caution. Because cyanide is highly toxic, the ancient alchemists were well aware of the danger of poison and must control it with exquisite methods.
On the reaction path, the intermediate product containing triethoxysilyl group and cyanobenzene should be prepared separately, and then the coupling should be made. Appropriate solvents can be found, such as alcohols and ethers. Such solvents are also commonly used in ancient brewing and pharmaceuticals. Use in solvents, at appropriate temperature and time, to make the two react. When reacting, close observation is required, such as ancient cooking medicine, depending on the heat, color and smell, timely adjustment. Or a little auxiliary agent can be added to promote the smooth reaction. This auxiliary agent may be a natural mineral or plant extract, selected according to experience.
After synthesis, the separation and purification of the product is also critical. Ancient methods or filtration, distillation, and recrystallization methods. Filter insoluble impurities with cloth and sieve; separate the product and solvent by distillation according to the difference in boiling point; improve the purity of the product by recrystallization. These are all ancient techniques, and can be used flexibly according to the characteristics of the product.

For 1% 2C4-bis (triethylamino) -2-naphthonitrile, there are a number of urgent precautions during storage and transportation.
First, this substance is extremely sensitive to temperature. High temperature can easily cause its properties to mutate, or cause chemical reactions, so it needs to be stored in a cool place, and the temperature should be constant, so as not to cause large fluctuations. If it is in a hot season, especially pay attention to the temperature control of storage and transportation tools to ensure its quality.
Second, humidity is also the key. High humidity environment can cause its moisture absorption, or hydrolysis and other reactions, which will damage its purity and efficiency. Therefore, the storage place must be dry, and a dry atmosphere can be maintained with the assistance of desiccants. When transporting, it is also necessary to prevent the intrusion of external moisture, such as sealed packaging, choose dry weather transportation, etc.
Third, this substance must be tight in terms of packaging. Due to slight leakage, not only will its own quality be damaged, but also it may be potentially harmful to the surrounding environment and personnel. Packaging materials should be resistant to the chemical properties of this substance and have a certain strength, so that they will not be damaged during transportation.
Fourth, light should not be underestimated. Long-term strong light exposure, or cause its photochemical reaction, changes the structure and properties. Therefore, the storage place should be dark, and the packaging should also be shaded during transportation, such as dark packaging materials.
Fifth, during transportation, avoid violent vibration and collision. Damage due to its structure or due to external impact, affecting quality. When handling, when handled with care, the transportation vehicle should also run smoothly to avoid potholes and bumpy roads.
Sixth, be cautious when dealing with other chemicals. This substance may react with certain chemicals, so during storage and transportation, it must not be mixed with contraindicated chemicals, so as not to cause danger.

1% 2C4 - Bis (triethoxy) - 2 - naphthol has many safety risks associated with this substance. It is chemically active or causes an uncontrolled reaction due to improper operation. If it is exposed to high temperature, water or contact with specific substances, or causes a violent reaction, there is a risk of explosion.
From a toxic point of view, it may irritate the skin, and can cause redness, swelling, itching, and pain after contact. If it is not carefully entered into the eyes, it will cause strong irritation to the eyes, which can seriously damage vision. Inhalation of its dust or volatiles can irritate the respiratory tract, causing cough, asthma, and long-term exposure may even cause respiratory diseases. And its toxicity or absorption through the digestive system, damage the gastrointestinal tract after accidental ingestion, nausea, vomiting, abdominal pain and other symptoms, may also affect important organs of the human body, threatening life and health.
Furthermore, it is not friendly to the environment. Entering water bodies will endanger aquatic organisms, affect the ecological balance of water bodies, and interfere with the growth, reproduction and survival of aquatic organisms. It flows into the soil, or changes the properties of the soil, affecting soil microbial activities and plant growth. Residues in the environment may also be transmitted through the food chain, causing potential harm to high nutrient-level organisms.
For storage, specific conditions are required. It should be placed in a cool, dry, well-ventilated place, away from fire sources, heat sources and oxidants, etc. Otherwise, improper storage will cause safety accidents. During transportation, it is also necessary to follow strict regulations and standards according to its dangerous characteristics, and take corresponding protective measures to ensure transportation safety.
