Methyltriethoxysilane has a wide range of uses and is important in various industrial fields. First, in the construction field, it is often used as a waterproof agent. It can penetrate into the pores of building materials and form a hydrophobic film on the surface. If masonry, concrete, etc. are treated with it, it can greatly reduce water absorption, increase impermeability and frost resistance. It is like covering the building with a water barrier, making it durable under wind, rain, frost and snow. Second, in the coating industry, it is a key additive. It can improve the adhesion of the coating, make the coating adhere to the base material, and increase the weather resistance and chemical corrosion resistance of the coating. If the metal surface is coated with a coating containing this ingredient, it can effectively prevent metal rust, and it seems to add a protective shield to the metal, prolonging its service life. Third, in the plastics and rubber industry, it can be used as a coupling agent. It can enhance the bonding force between inorganic fillers and organic polymers, and significantly improve the mechanical properties of plastics and rubber, such as strength and toughness. Make plastic products stronger and more durable, and rubber products have better elasticity and wear resistance, just like giving new vitality to materials. Fourth, in the electronics industry, it also has important applications. In electronic packaging materials, it helps to improve the bonding force and sealing performance between materials and electronic components, and ensures the stable operation of electronic components, free from external environmental intrusion, such as moisture, dust, etc., which seems to build a safe nest for electronic components. In summary, methyltriethoxysilane plays an indispensable role in the construction, coatings, plastics, rubber and electronics industries, contributing to the development of various industries.

Methyltriethoxysilane is a kind of organosilicon compound. Its physical properties are quite unique and it has important uses in many fields of industry. Looking at its properties, under normal temperature and pressure, this is a colorless, transparent and pungent odor liquid. Its boiling point is between 148 and 154 degrees Celsius. At this temperature, the liquid is converted into a gaseous state, which can be separated and purified by distillation. The melting point is about -77 ° C. It is solid at low temperature, and gradually melts into a liquid when the temperature rises. In terms of density, it is about 0.89 to 0.90g/cm ³, which is slightly lighter than water. Therefore, if mixed with water, it will float on the water surface. Its solubility also has characteristics. It can be soluble in most organic solvents, such as ethanol and ether, but it is difficult to dissolve in water. However, it can slowly hydrolyze in water to generate corresponding silanol and ethanol. In addition, the flash point of methyl triethoxysilane is about 33 ° C, which is a flammable liquid. It is very easy to burn in case of open flame and hot topic. When storing and using, special attention should be paid to fire safety. Its vapor is heavier than air and can spread to a considerable distance at a lower place. In case of fire source, it will catch fire and backfire. This is also a risk that needs to be prevented when using. Due to its unique physical properties, it is widely used in coatings, adhesives, sealants and other fields, which can enhance the adhesion, water resistance and weather resistance of materials.

Methyltriethoxysilane, when storing, many things need to be paid attention to. This material is flammable, so the first fire protection. It should be stored in a cool and ventilated place, away from fire and heat sources, and the storage temperature should not exceed 30 ° C. Its vapor and air can form an explosive mixture. In case of open flame and high heat energy, it is strictly forbidden to store fireworks in the storage site, and suitable fire equipment must be prepared. Furthermore, this material is sensitive to moisture and easy to hydrolyze. The storage environment must be kept dry, and the packaging must be tightly sealed to prevent moisture from invading and causing it to deteriorate. The handling process should also be handled lightly to avoid damage to the packaging and contact with air and moisture. In addition, methyltriethoxysilane has certain toxicity. The storage area should be kept away from crowded places, and good ventilation equipment is required to prevent the volatile gas from being harmful to the human body. At the same time, it should be stored separately from oxidants and acids, and must not be mixed. Contact with it may cause a violent reaction and endanger safety. In addition, the storage site should be set up with obvious warning signs to remind personnel of its danger. Management personnel need to be professionally trained and familiar with the characteristics of the substance and emergency treatment methods. Regularly check the storage equipment and packaging. If there is any leakage and other abnormalities, take appropriate measures to dispose of them immediately to ensure the safety of the storage process.

The method of preparing methyltriethoxysilane is described in many ancient books. The main one is to use methyltrichlorosilane and absolute ethanol as raw materials to carry out the reaction of alcoholysis. First put an appropriate amount of absolute ethanol in a clean reactor and cool it down by means of an ice bath. When the temperature is moderate, slowly add methyltrichlorosilane dropwise, during which the reaction temperature must be carefully observed, and the reaction temperature should not be too high, because the reaction is quite exothermic. After adding dropwise, maintain the reaction temperature within a certain range, and often use a stirring device to make the reactants uniform and promote the full reaction. When the reaction occurs, the generated hydrogen chloride gas escapes, which can be directed to the absorption device and collected with water or alkali solution to avoid polluting the environment. At the end of the reaction, the product is separated and purified by distillation. Distillation under normal pressure first, except for its impurities with low boiling point, followed by distillation under reduced pressure to obtain pure methyltriethoxysilane. There are other methods, such as using silicon powder, methanol, and hydrogen chloride as starting materials to prepare a mixture of methylchlorosilane first, and then fractionating to obtain methyltrichlorosilane. The subsequent steps are similar to the previous method. However, the former step is relatively simple and is a common preparation method. When preparing, the ratio of various materials, reaction temperature and time must be precisely controlled to obtain high-purity methyltriethoxysilane.

Methyltriethoxysilane, when using, many safety issues must not be ignored. This is a volatile silicone compound, which is widely used in chemical, building materials, electronics and other fields. First, fire prevention and explosion-proof is essential. Methyltriethoxysilane is flammable, and it is very easy to burn and explode in case of open flames and hot topics. Therefore, in the place of use, fireworks must be strictly prohibited, and suitable fire-fighting equipment should be equipped. When storing, it should also be kept away from fire and heat sources, placed in a cool and ventilated place, and the warehouse temperature should not be too high. Second, it is related to human protection. Its volatile gas may have a stimulating effect on the eyes and respiratory mucosa. When working, wear appropriate protective glasses to prevent splashing into the eyes; wear a gas mask to protect the respiratory tract; wear protective clothing and protective gloves to avoid skin contact. If you come into contact accidentally, you should quickly rinse with a lot of water, and in severe cases, you need to seek medical treatment. Third, the environmental impact should not be underestimated. If it leaks into the environment, or causes pollution to water and soil. Therefore, during the operation, you need to beware of water pollution and work in a well-ventilated place to prevent the accumulation of harmful gases. In case of leakage, personnel in the contaminated area should be quickly evacuated to a safe place, isolated, and strictly restricted from entering and leaving. Emergency responders wear self-contained positive pressure breathing apparatus and fire protective clothing. Do not let leaks come into contact with combustible substances. Small leaks should be absorbed by inert materials such as sand and vermiculite. If a large amount leaks, build a dike or dig a pit for containment, cover it with foam to reduce steam disasters, and then transfer it to a tanker or a special collector with an explosion-proof pump for recycling or transportation to a waste treatment site for disposal.
