HEXACHLORODISILANE Chemical Properties,Usage,Production

Chemical Properties

colourless liquid

Physical properties

bp 144–145.5 °C; d 1.562 g cm?3.

Uses

Hexachlorodisilane can be used in deoxygenation and desulfurization of phosphine oxides, phosphine sulfides, and amine oxides; reducing agent for nitro groups and sulfur diimides.

Uses

HCDS may be used as a reducing agent. It may be combined with ammonia to form silicon nitride by chemical vapor deposition(CVD) technique.

Reactions

Hexachlorodisilane is a versatile chemical reagent that can be used in the following chemical reactions^[1-2]:
(1) When hexachlorodisilane is heated with a catalytic amount of triphenylphosphine or triphenylarsine, it decomposes according to the equation nSi2Cl6 = nSiCl4 + (SiCl2)n. It does not react with trifluoromethylphosphine. Hexabromodisilane is also decomposed by trimethylamine.
(2) Hexachlorodisilane reacts with hydrogen chloride in the presence of pyridine, and the reaction formula is:
Si2Cl6 + 2HCl = 2SiCl4 + H2.
(3) Excess hydrogen bromide and hexachlorodisilane produce a mixture of hydrogen chloride and hydrogen bromide.
(4) Hexachlorodisilane reacts with methyl chloride in the presence of triphenylphosphine to produce a mixture of methyltrichlorosilane and silicon tetrachloride. When hexachlorodisilane and methyl bromide are heated together in the presence of triphenylphosphine, a mixture of methyl chloride and bromine is produced.
(5) Hexachlorodisiloxane reacts with sulfur trioxide to produce silicon dioxide, sulfur dioxide and hexachlorodisiloxane.

General Description

Hexachlorodisilane (HCDS) is a chlorosilane used as a precursor for producing disilanes. It is a dioxidizer that is used in the production of silicon films and silicon nitride based films.
