Phenyltrimethoxysilane (CAS 2996-92-1), a prominent organosilane, is characterized by its unique chemical structure and reactivity, making it highly valuable across numerous industrial sectors. Understanding its chemical properties is key to leveraging its full potential in applications such as silicone resin synthesis, surface modification, and advanced material development. As a specialized chemical producer, we offer high-purity Phenyltrimethoxysilane and insights into its critical role.

Chemical Properties and Reactivity:

Phenyltrimethoxysilane is a colorless to light yellow transparent liquid with a molecular formula of C9H14O3Si and a molecular weight of approximately 198.29 g/mol. Its key chemical feature is the presence of three methoxy groups attached to a silicon atom, along with a phenyl group. The methoxy groups are susceptible to hydrolysis, especially in the presence of moisture or water, a reaction that forms silanol (Si-OH) groups. These silanol groups can then undergo condensation reactions to form siloxane (Si-O-Si) bonds, leading to the formation of polymers and networks. This trifunctional nature allows Phenyltrimethoxysilane to act as a crosslinking agent, contributing to the formation of robust, three-dimensional structures.

Key physical properties include a boiling point of around 233 °C, a melting point of -25 °C, and a density of approximately 1.062 g/mL at 25 °C. It is sensitive to moisture and should be stored in a cool, dry place under an inert atmosphere to maintain its integrity. For formulators looking to buy Phenyltrimethoxysilane, these properties dictate its handling and application methods.

Industrial Significance and Applications:

  • Silicone Resin Production: PTMS is extensively used as a monomer or crosslinking agent in the synthesis of silicone resins, particularly those requiring high thermal stability and mechanical strength.
  • Surface Modification: It is employed to modify the surface properties of inorganic materials, rendering them hydrophobic and improving their compatibility with organic polymers.
  • Coatings and Sealants: As an additive, Phenyltrimethoxysilane enhances the performance of coatings and sealants by improving adhesion, durability, and weather resistance.
  • Material Science Research: Its role in sol-gel processes makes it invaluable for developing novel materials for electronics, optics, and nanotechnology.
