It is a versatile chemical compound that finds application in various industries such as construction, automotive, textiles, and electronics, among others. INNO Specialty Chemicals, a leading manufacturer and supplier from China, produces high-quality triacetoxypropylsilane that meets the international standards of quality and safety.

Properties and Synthesis of Triacetoxypropylsilane

Triacetoxypropylsilane has a molecular formula of C9H18O6Si and a molecular weight of 258.32 g/mol. It has a boiling point of 220-222°C and a density of 1.11 g/cm^3 at 25°C. The chemical structure of triacetoxypropylsilane consists of a propyl group attached to a silicon atom through a carbon-silicon bond, and three acetate groups attached to the silicon atom through oxygen-silicon bonds.

Triacetoxypropylsilane is synthesized by reacting propyltriethoxysilane with acetic anhydride in the presence of a catalyst such as hydrochloric acid or zinc chloride. This reaction results in the substitution of the ethoxy groups with acetate groups, forming triacetoxypropylsilane and ethanol as a by-product. The reaction is carried out under controlled conditions of temperature and pressure to ensure the purity and yield of the product.

Applications of Triacetoxypropylsilane
