Diphenyldimethoxysilane (DPDMS), identified by CAS number 6843-66-9, is a versatile organosilicon compound characterized by its colorless, transparent liquid appearance. Understanding its chemical and physical properties is fundamental for its effective and safe utilization in various industrial applications. NINGBO INNO PHARMCHEM CO.,LTD., a prominent chemical supplier in China, ensures that its DPDMS meets high standards for purity and consistency, facilitating seamless integration into manufacturing processes.

Key Chemical and Physical Properties:

  • Molecular Formula: C14H16O2Si
  • Molecular Weight: 244.36 g/mol
  • Appearance: Colorless transparent liquid. This clarity is crucial for applications where optical transparency is a requirement.
  • Purity: Typically supplied at a minimum of 99.0%, ensuring high efficacy in catalytic reactions and material synthesis.
  • Boiling Point: Approximately 286°C. This relatively high boiling point indicates stability under moderate processing conditions.
  • Flash Point: Around 121°C. This indicates a moderate flammability risk, necessitating careful handling away from open flames and ignition sources.
  • Density: Approximately 1.08 g/cm³.
  • Refractive Index: Around 1.541, contributing to its optical clarity.

Storage and Handling Best Practices:

To maintain the integrity and quality of Diphenyldimethoxysilane, proper storage and handling are essential. NINGBO INNO PHARMCHEM CO.,LTD. advises the following:

  • Storage Conditions: Store in a cool, dry, and well-ventilated area. Keep containers tightly sealed to prevent moisture absorption, which can lead to hydrolysis of the methoxy groups.
  • Incompatible Materials: Avoid contact with strong oxidizing agents, acids, and bases.
  • Handling Precautions: Ensure adequate ventilation when handling the material. Use appropriate personal protective equipment (PPE), including gloves, safety glasses, and protective clothing, to avoid skin and eye contact. Due to its flash point, keep it away from heat, sparks, and open flames.
  • Packaging: DPDMS is commonly packaged in 200 kg drums, but customized packaging solutions are often available from suppliers like NINGBO INNO PHARMCHEM CO.,LTD. to meet specific industrial needs.

By adhering to these guidelines, industries can ensure the safe and effective use of Diphenyldimethoxysilane, leveraging its valuable properties as a chemical intermediate and catalyst component. For businesses seeking a reliable Diphenyldimethoxysilane manufacturer in China, NINGBO INNO PHARMCHEM CO.,LTD. offers quality products backed by technical expertise.
