Disilane | CAS No. 1590-87-0

Q: What are the physical and chemical properties of Disilane (CAS: 1590-87-0)?

Disilane (CAS: 1590-87-0) is a colorless gas with a density of 0.571 g/L at standard temperature and pressure. It has a molecular weight of 64.13 g/mol and is highly reactive. Disilane is not very soluble in water but soluble in organic solvents. It readily undergoes hydrolysis and is highly flammable.

Q: How is Disilane (CAS: 1590-87-0) typically synthesized?

Disilane is typically synthesized via the thermal decomposition of silanols or silanols in the presence of hydride reagents or by the hydrogenation of siloxanes. The reaction is carried out under an inert atmosphere to prevent oxidation, and various catalysts such as Raney nickel are used to improve selectivity and yield.

Q: What industries use Disilane (CAS: 1590-87-0)?

Disilane is widely used in industries such as semiconductor manufacturing, where it serves as a precursor for silicon-based materials. It is also used in the production of high-purity silicon for photovoltaic applications, and in the synthesis of organosilicon compounds for use in polymers and pharmaceuticals.

Q: What precautions should be taken when handling Disilane (CAS: 1590-87-0)?

Handling Disilane requires strict safety measures due to its high reactivity and flammability. Personal protective equipment (PPE) such as gloves, goggles, and a respirator should be worn. Work should be conducted in a fume hood. Spills should be handled with caution using appropriate non-sparking tools, and the area should be well-ventilated. Safety data sheets (SDS) should be consulted for detailed information on handling and emergency procedures.
