Triacetoxy(methyl)silane: A Versatile Chemical for Modern Applications

Triacetoxy(methyl)silane, also known as Wacker ES 15, is a colorless and transparent liquid with a pungent odor. It is a type of organosilicon compound that has a wide range of industrial applications. INNO SPECIALTY CHEMICALS is a leading manufacturer and supplier of triacetoxy(methyl)silane from China.

Chemical Properties and Synthesis

Triacetoxy(methyl)silane has a molecular formula of C7H14O6Si and a molecular weight of 246.27 g/mol. It has a boiling point of 126-127°C at 760 mmHg and a flash point of 44°C. The chemical structure of triacetoxy(methyl)silane comprises a silicon atom that is covalently bonded to three acetate groups and one methyl group.

Triacetoxy(methyl)silane is synthesized by the reaction of methyltrichlorosilane (MTCS) with acetic anhydride in the presence of a catalyst such as pyridine or triethylamine. The resulting product is a mixture of triacetoxy(methyl)silane and other byproducts such as acetic acid, hydrogen chloride, and methyl acetate. The crude product is then purified by distillation or chromatography to obtain pure triacetoxy(methyl)silane.

Applications of Triacetoxy(methyl)silane

Triacetoxy(methyl)silane is a versatile chemical that is used in various industrial applications such as:

1. Crosslinking agent: Triacetoxy(methyl)silane is used as a crosslinking agent in the production of silicone rubber, silicone sealants, and silicone adhesives. It reacts with hydroxyl groups on the surface of silica or other substrates to form a crosslinked network that enhances the mechanical strength and thermal stability of the final product.

2. Surface modifier: Triacetoxy(methyl)silane is used as a surface modifier for glass, ceramics, and metals. It forms a thin layer of siloxane on the surface of the substrate, which improves the wetting, adhesion, and corrosion resistance of the substrate.

3. Coupling agent: Triacetoxy(methyl)silane is used as a coupling agent in the production of composites and reinforced plastics. It improves the interface adhesion between the filler and the polymer matrix, which enhances the mechanical properties of the final product.

4. Sol-gel precursor: Triacetoxy(methyl)silane is used as a precursor for sol-gel synthesis of silica, silica-based materials, and hybrid organic-inorganic materials. It undergoes hydrolysis and condensation reactions to form a gel that can be dried and calcined to obtain a solid material with tailored properties.

5. Chemical intermediate: Triacetoxy(methyl)silane is used as a chemical intermediate in the synthesis of other organosilicon compounds such as methyltriacetoxysilane, vinyltriacetoxysilane, and phenyltriacetoxysilane.

Safety and Handling

Triacetoxy(methyl)silane is a hazardous chemical that can cause skin and eye irritation, respiratory problems, and fire or explosion hazards. It should be handled with caution in a well-ventilated area, with appropriate personal protective equipment such as gloves, goggles, and respirators. It should be stored in a cool, dry, and well-ventilated area, away from heat sources and incompatible materials.

Conclusion

Triacetoxy(methyl)silane is a versatile and valuable chemical that has a wide range of industrial applications. Its unique chemical structure and properties make it an essential ingredient in the production of various materials and products that we use in our daily lives. INNO SPECIALTY CHEMICALS is a reliable and experienced manufacturer and supplier of triacetoxy(methyl)silane from China, who can provide high-quality products and services to customers worldwide.
