Triethoxy (3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9, 9, 10, 10-heptadecafluorodecyl) What are the main application fields of silane

Triethoxy (3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9, 9, 10, 10 - heptadecafluorodecyl) silane, also known as heptafluorodecyl triethoxysilane, is a special category of organosilicon compounds. This compound is widely used and has important applications in many industrial and scientific fields.

It is the first to bear the brunt and plays a key role in the field of material surface treatment. Due to its unique chemical structure, it can build a very stable and low surface energy protective film on the surface of the material. This film is like a "stealth armor" on the material, giving the material excellent water, oil and anti-fouling properties. Taking the fabric as an example, after being treated with this compound, the fabric is like a lotus leaf, water droplets and oil droplets are difficult to adhere, easy to roll off, greatly improving the fabric's anti-fouling ability, making it shine in outdoor clothing, home textiles and other products, which can not only maintain cleanliness for a long time, but also does not affect the original breathability and softness of the fabric.

Furthermore, in the field of electronics, it is also indispensable. Electronic components often need to withstand harsh environmental tests, and heptafluorodecyl triethoxysilane can form a protective film on the surface of the component, effectively isolating moisture and corrosive substances, acting as a loyal guard to protect the stability and reliability of electronic components. Not only that, its low surface energy characteristics can also help improve the lubricity of the surface of electronic components, reduce the coefficient of friction, reduce wear and tear, and prolong the service life of components. It plays a pivotal role in the manufacture of key electronic components such as integrated circuits and display screens.

In addition, in the field of optics, this compound has also emerged. Applying it to the surface treatment of optical lenses can effectively reduce the surface reflectivity of the lens, improve the light transmittance, and make the image clearer. At the same time, the formed protective film can also enhance the wear resistance and scratch resistance of the lens, and ensure the stability of the optical performance of the lens during long-term use. It is widely used in the manufacture of optical equipment such as camera lenses and telescope lenses.

In a word, Triethoxy (3, 3, 4, 4, 5, 5, 6, 7, 7, 8, 8, 9, 9, 10, 10, 10 - heptadecafluorodecyl) silane, with its unique properties, occupies an important position in the fields of material surface treatment, electronics and optics, and has made great contributions to the improvement of product performance and technological progress in various industries.

What are the physical and chemical properties of triethoxy (3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9, 9, 10, 10-heptadecafluorodecyl) silane

Triethoxy (3, 3, 4, 4, 5, 5, 6, 6, 7, 8, 8, 9, 10, 10 - heptadecafluorodecyl) silane, the Chinese name is often heptadecyl fluorodecyl triethoxysilane. The physical properties of this substance are special, so let me explain them one by one.

Its outer surface is often black to light colored liquid. In terms of solubility, it is easily soluble in many soluble solutions, such as toluene and acetone. This is due to the fact that the soluble groups contained in the molecule can form a good interaction.

In terms of melting and boiling, due to the characteristics of the molecular force, boiling and boiling can be determined under specific conditions. The boiling value is slightly different due to the fixed conditions, but it generally falls within a certain range.

The surface property is outstanding, and this compound has a low surface energy. Due to the fact that there are many fluorine atoms in its molecules, the fluorine atoms have high performance and are half small, which can form a dense arrangement on the surface of the object, greatly reducing the surface energy. Therefore, its coating on the surface of the material can make the material exhibit excellent hydrophobicity and oleophobicity. Water droplets or oil droplets contact the surface of the object, such as beads slipping off, for adhesion.

The qualitative properties of the chemical are also good. Due to the reason of silicone and fluorocarbon, it is not easy to react to other substances in general environments. It can withstand the invasion of polymers and other substances, and can maintain its own stability in the environment of different assimilations such as acids and chemicals. This characteristic makes it useful in many special environments.

Therefore, Triethoxy (3, 3, 4, 4, 5, 5, 6, 6, 7, 8, 8, 9, 9, 10, 10, 10 - heptadecafluorodecyl) silane has important uses in many fields such as materials, materials, and building materials due to its special physical properties.

What is the preparation method of Triethoxy (3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9, 9, 10, 10-heptadecafluorodecyl) silane

Triethoxy (3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9, 9, 10, 10 - heptadecafluorodecyl) silane is a silicone compound with special surface properties and is widely used in the field of materials science. Its preparation method is as follows:

First take 3, 3, 4, 4, 5, 5, 6, 7, 8, 8, 9, 9, 10, 10, 10 - heptadecafluorodecyl - 1 - ol and triethoxysilane and place them in the reaction vessel according to a certain molar ratio. This ratio needs to be precisely adjusted, which is the key to the reaction. Usually, the molar ratio of the two is 1:1.2 to 1:1.5 to ensure that the raw materials are fully reacted and the product yield and purity are excellent.

Add an appropriate amount of catalysts, such as organotin catalysts, such as dibutyltin dilaurate. It can significantly accelerate the reaction process and improve the reaction efficiency. The amount of catalyst used is very particular, generally 0.5% to 2% of the total mass of the reactants. If the amount is too small, the catalytic effect is not good; if it is too much, side reactions may occur.

Stir in a nitrogen-protected atmosphere and heat up to 80-120 ° C. Nitrogen protection is essential to prevent the reaction of reactants with air components and affect the quality of the product. This temperature range has been verified by repeated experiments to enable the reaction to proceed smoothly and efficiently. The reaction lasts for 6-12 hours, during which the reaction process is closely monitored and can be tracked by thin-layer chromatography or gas chromatography.

After the reaction is completed, the product contains unreacted raw materials, catalysts and by-products, and needs to be refined and separated. Distillation under reduced pressure was used to remove impurities with low boiling point. Then, silica gel was selected as the stationary phase, and the mixture of n-hexane and ethyl acetate was selected as the mobile phase. According to the difference in the partition coefficients of different substances in the stationary phase and the mobile phase, the product and impurities were separated to obtain high-purity Triethoxy (3, 3, 4, 5, 5, 6, 7, 7, 8, 8, 9, 9, 10, 10 - heptadecafluorodecyl) silane.

Bear the brunt and be safe. This compound contains fluoride, some fluoride or toxic, and contact with the skin and inhalation of its vapors may endanger health. Therefore, when using, be sure to wear appropriate protective equipment, such as gloves, goggles, gas masks, etc., to isolate the body from contact with the substance and prevent inhalation of harmful vapors.

Furthermore, its chemical properties need to be paid attention to in detail. The substance may react with specific chemicals. When storing and using it, it should be avoided in one place with strong oxidizing agents, strong acids, strong alkalis, etc., to prevent violent reactions and lead to safety accidents. At the same time, in view of its possible hydrolysis, the storage environment should be dry, away from humid storage, and the container should be sealed in time after use.

In addition, the operating environment should not be ignored. It should be used in a well-ventilated place to quickly disperse the volatile vapor, reduce the concentration in the air, and reduce the risk of inhalation. If operating in a laboratory, laboratory safety procedures should be followed; in industrial production, it is even more necessary to strictly follow relevant standards and procedures.

Finally, the disposal of waste after use should not be rushed. It is necessary to follow local environmental regulations, dispose of it properly, and do not discard it at will to avoid polluting the environment. In this way, Triethoxy (3, 3, 4, 4, 5, 6, 6, 7, 7, 8, 8, 9, 9, 10, 10, 10 - heptadecafluorodecyl) silane can be used safely and scientifically.
