What is the main use of Iso - Octyltriethoxysilane?
Isooctyl triethoxysilane, this is an organosilicon compound. It has a wide range of main uses and is of great value in many fields.
In the field of construction, it can be used as a water repellent agent. Caiin isooctyl triethoxysilane can penetrate into the interior of building materials, chemically react with hydroxyl groups in the material, and form a hydrophobic layer on the surface and internal pores of the material. In this way, it can effectively prevent moisture intrusion without affecting the air permeability of the material. For example, in the protection of stone components of ancient buildings, the application of this substance can prevent rain erosion, delay stone weathering, and preserve ancient buildings for a long time.
In the paint industry, it is an excellent additive. It can improve the adhesion between the paint and the substrate, and enhance the weather resistance and wear resistance of the paint. After adding isooctyl triethoxysilane, the paint can adhere more firmly to the surface of the object, and it is not easy to fall off, change color or powder after a long time of wind, sun, rain and other natural environment tests. Like some outdoor facilities coatings, after adding this material, it can greatly extend the service life and maintain a good appearance.
In the field of composites, isooctyl triethoxysilane plays a key role as a coupling agent. It can build a bridge between inorganic materials and organic materials and enhance the bonding force between the two interfaces. For example, in glass fiber reinforced plastics, it allows the glass fiber to be better combined with the resin matrix, thereby enhancing the mechanical properties of the composite material, significantly improving its strength, toughness, and other aspects. It is widely used in aerospace, automotive manufacturing, and other industries that require strict material properties.
What are the physical properties of Octyltriethoxysilane?
Isooctyl triethoxysilane is a class of organosilicon compounds. Its physical properties are quite unique, and I will describe them in detail for you.
Looking at its properties, it is mostly a colorless and transparent liquid under normal circumstances, just like clear water, clear and pure. The volatility of this liquid is relatively moderate, and it does not disappear quickly like a storm or a sticky thing for a long time.
As for its density, it is slightly lighter than water, floating on the water, like a boat wave. And its boiling point is also considerable, and it is in a specific temperature range, so that this substance can maintain a stable state in ordinary environments.
The solubility of isooctyl triethoxysilane is also extraordinary. In many organic solvents, it can blend with them, just like water emulsion, indistinguishable from each other. However, in water, it can only be slightly soluble, just like falling flowers into water, with slight ripples.
Its surface tension is low, which makes it easy to spread on the surface of the material, such as the coating of oil, uniform and flat. And it has good wettability, can be in close contact with many solid materials, like a close friend.
These physical properties make isooctyl triethoxy silane show its skills in many fields. For example, the waterproof industry of buildings can penetrate into the pores of masonry, forming a dense protective layer to resist the erosion of water, just like a strong shield. In the coatings industry, it can enhance the adhesion between coatings and substrates, making the coating stronger, just like armor.
Iso - Octyltriethoxysilane precautions in storage and transportation
When storing and transporting isooctyltriethoxysilane, many matters need to be paid attention to.
Temperature and humidity of its primary storage environment. This substance should be stored in a cool, dry and well-ventilated place. If the temperature is too high, it may cause its volatilization to accelerate, and even cause safety concerns; if the humidity is too high, it may react with water vapor, resulting in quality deterioration. Generally speaking, the storage temperature should be maintained at 5 ° C to 30 ° C, and the humidity should be controlled below 60%.
Furthermore, the choice of storage container is also critical. Use containers with good sealing performance, preferably glass and stainless steel, and avoid materials that are easy to react with isooctyltriethoxysilane, such as certain plastics. Due to the chemical activity of this substance, it is not suitable for container or chemical reaction with it, which affects its chemical properties.
When transporting, shock resistance and leakage prevention are the top priorities. During transportation of this substance, it is necessary to ensure that the packaging is firm to prevent bumps and collisions from damaging the packaging and leaking. If it is transported by road, the vehicle needs to be equipped with corresponding emergency treatment equipment and protective equipment to deal with emergencies. And the transportation vehicle should be kept away from fire and heat sources and avoid direct sunlight.
In addition, whether it is storage or transportation, it is necessary to strictly follow relevant regulations and standards. Operators should also have professional knowledge and be familiar with the characteristics of isooctyltriethoxysilane and emergency treatment methods. In this way, the safety and quality of isooctyltriethoxysilane during storage and transportation can be guaranteed.
Iso - Is Octyltriethoxysilane chemically stable?
The chemical properties of isooctyl triethoxy silane are quite stable. In this compound, the silicon atom is connected to three ethoxy groups, and the ethoxy group structure is relatively stable, which can form a certain protection for the silicon atom. And the silicon-oxygen bond energy is relatively high, and more energy needs to be supplied to make it break and react.
Under normal conditions, it is quite resistant to general acid-base and oxidative reducing agents. At room temperature, pressure and without special catalysts, it rarely reacts spontaneously with common inorganic and organic compounds. Even in contact with water, although the ethoxy group can be gradually hydrolyzed, the hydrolysis process is relatively slow, and it is difficult to proceed rapidly and completely without specific acceleration conditions.
Furthermore, the isooctyl part in the molecule, as a larger organic group, can increase the steric hindrance effect of the molecule. This steric hindrance makes it difficult for external reagents to get close to the silicon atom, further enhancing its chemical stability. Therefore, isooctyl triethoxysilane can maintain relatively stable chemical properties in many practical application scenarios, which can meet the needs of chemical stability in fields such as material surface protection.
What is the preparation method of Iso - Octyltriethoxysilane
The method of preparing isooctyl triethoxysilane is to combine isooctyl chloride with sodium triethoxysilyl alcohol. First take an appropriate amount of isooctyl chloride, which is prepared or obtained by the action of isooctyl alcohol and chlorination reagents such as sulfinyl chloride. Isooctyl alcohol needs to be selected with excellent quality. When reacting, the temperature control is moderate, so that the reaction can proceed smoothly. Isooctyl chloride can be obtained, and it needs to be refined and purified to remove impurities.
Secondary preparation of triethoxysilyl alcohol sodium, with silanol and sodium ethanol reaction. The choice of silanol is related to the purity of the product, and the quality of sodium ethanol is also important. The two are reacted in a suitable solvent. The solvent needs to be affinity with the reactants and do not produce side reactions. Control its conditions to obtain pure sodium triethoxysiloxides.
Then, the prepared isooctyl chloride and sodium triethoxysiloxides are put into the reaction kettle in proportion, and the right catalyst is selected to promote the rapid reaction. During the reaction, the temperature, pressure and time are strictly controlled to fully combine the two. After the reaction is completed, the product is separated and purified by techniques such as distillation and extraction. During distillation, according to the boiling point of isooctyl triethoxysilane, temperature-controlled distillation is used to remove unfinished matter and impurities, and finally high-purity isooctyl triethoxysilane is obtained. This preparation method requires each step to be fine in order to obtain excellent yield.
