Ethyl Orthosilicate: Properties, Applications, and Manufacturing
Ethyl Orthosilicate, also known as Tetraethyl Orthosilicate (TEOS), is a colorless and transparent liquid with a pungent odor. It is a versatile and widely used chemical in various industries, especially in the production of silica-based materials. As a manufacturer and supplier from China, INNO Specialty Chemicals provides high-quality Ethyl Orthosilicate to meet the demands of different applications.
Properties of Ethyl Orthosilicate
Ethyl Orthosilicate has the chemical formula Si(OC2H5)4 and a molecular weight of 208.33 g/mol. It is soluble in organic solvents such as alcohol, acetone, and benzene, but insoluble in water. Ethyl Orthosilicate is highly reactive and hydrolyzes rapidly in the presence of water or moisture, forming silicic acid and ethanol. The reaction is exothermic and can be accelerated by the addition of acid or base catalysts.
Applications of Ethyl Orthosilicate
Ethyl Orthosilicate is widely used in the production of silica-based materials due to its unique properties and reactivity. The following are some of the most common applications of Ethyl Orthosilicate:
1. Silica gel and aerogel: Ethyl Orthosilicate is used as a precursor for the production of silica gel and aerogel, which are highly porous materials with high surface area and excellent adsorption properties. Silica gel is commonly used as a desiccant and catalyst support, while aerogel has applications in thermal insulation, acoustic damping, and energy storage.
2. Coatings and films: Ethyl Orthosilicate is used as a precursor for the production of silica-based coatings and films, which can provide excellent adhesion, hardness, and chemical resistance. Silica coatings and films are commonly used in the automotive, aerospace, and electronics industries.
3. Optical fibers: Ethyl Orthosilicate is used as a precursor for the production of high-purity silica glass, which is used in the manufacturing of optical fibers for telecommunications, data transmission, and medical devices. Silica glass has excellent optical properties, such as low attenuation, high refractive index, and high UV resistance.
4. Ceramics: Ethyl Orthosilicate is used as a precursor for the production of ceramic materials, such as silicon carbide, silicon nitride, and silica ceramics. These materials have high mechanical strength, thermal stability, and chemical resistance, and are used in various applications, such as cutting tools, wear-resistant coatings, and electronic components.
Manufacturing of Ethyl Orthosilicate
Ethyl Orthosilicate can be produced by the reaction of silicon tetrachloride with ethanol in the presence of a catalyst, such as hydrochloric acid or aluminum chloride. The reaction produces Ethyl Orthosilicate and hydrogen chloride as byproducts. The crude product can be purified by distillation or fractional crystallization to obtain high-purity Ethyl Orthosilicate.
