FAQ

What are the physical and chemical properties of Tribenzylsilane (CAS: 1747-92-8)?

Tribenzylsilane (CAS: 1747-92-8) is a colorless liquid with a molecular weight of approximately 272.41 g/mol. It has a high boiling point of about 255°C and low solubility in water. It is reactive towards hydrolysis and can form silanol groups under acidic conditions. Tribenzylsilane is insoluble in water but miscible with organic solvents such as ethers and alcohols.

How is Tribenzylsilane (CAS: 1747-92-8) typically synthesized?

Tribenzylsilane (CAS: 1747-92-8) is typically synthesized by reacting benzene with silicon tetrachloride in the presence of a Lewis acid catalyst, such as aluminum chloride. The reaction involves the displacement of chlorine atoms by benzene rings, leading to the formation of the tribenzylsilane product with good yield and high selectivity.

What industries use Tribenzylsilane (CAS: 1747-92-8)?

Tribenzylsilane (CAS: 1747-92-8) finds applications in various industries, including pharmaceuticals, where it is used as a precursor for synthesis of organic compounds and intermediates. In the polymer industry, it serves as a monomer for preparing specialized polymers. It is also utilized in sensor technology and semiconductor fabrication due to its reactive properties and ability to form stable silicon-based compounds.

What precautions should be taken when handling Tribenzylsilane (CAS: 1747-92-8)?

When handling Tribenzylsilane (CAS: 1747-92-8), it is essential to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or fume hood to minimize inhalation risks. Spills should be managed carefully using absorbent materials, and the spilled area should be flushed with water. Always refer to the safety data sheet (SDS) for detailed hazardous properties and emergency procedures.
