Phenyltrimethoxysilane (CAS 2996-92-1), often abbreviated as PTMS, is a critically important organosilane compound with widespread industrial applications. At NINGBO INNO PHARMCHEM CO.,LTD., we specialize in the production and supply of high-quality PTMS, understanding its fundamental role in various advanced materials and chemical processes. This article aims to provide a detailed overview of its properties, synthesis pathways, and its indispensable contribution to industries.
Chemically, Phenyltrimethoxysilane is characterized by a phenyl group (C₆H₅) bonded to a silicon atom, which is further bonded to three methoxy groups (-OCH₃). This structure, with the chemical formula C₉H₁₄O₃Si and a molecular weight of approximately 198.29 g/mol, grants PTMS a unique combination of reactivity and stability. It typically presents as a colorless, transparent liquid with a mild odor. Its physical properties include a boiling point around 233°C, a density of approximately 1.06 g/cm³ at 25°C, and a refractive index of about 1.4680. These properties influence its handling, storage, and performance in various applications.
The synthesis of phenyltrimethoxysilane commonly involves the direct reaction of phenyl Grignard reagent with silicon tetrachloride, followed by methoxylation, or through the hydrosilylation of phenylacetylene with trimethoxysilane. The purity of the synthesized PTMS is crucial for its performance as a crosslinking agent and intermediate. NINGBO INNO PHARMCHEM CO.,LTD. employs rigorous quality control measures to ensure that our phenyltrimethoxysilane meets high purity standards, making it suitable for demanding applications where you might need to buy phenyltrimethoxysilane for your formulations.
Industrially, PTMS is highly valued for its ability to enhance the thermal stability of other silanes and its role as a crosslinking agent for silicone resins. It is a key raw material for producing phenyl silicone oil and phenyl silicone rubber, materials known for their excellent performance at high temperatures and their resistance to oxidation. Furthermore, its application in modifying the surface of inorganic fillers makes them more hydrophobic, improving their dispersion in polymers and enhancing the overall properties of composite materials. For businesses looking for a reliable supplier to purchase phenyltrimethoxysilane, NINGBO INNO PHARMCHEM CO.,LTD. offers consistent quality and expert support, ensuring your projects benefit from this versatile chemical compound.
