English Name: Hexamethyldisilazane
CAS No.: 999-97-3
Molecular formula: C6H19NSi2
Molecular weight: 161.39
EINECS No.: 213-668-5
Melting point: - 78 ° C
Boiling point: 125 ° C (lit.)
Density: 0.774 g / ml at 25 ° C (lit.)
Chemical properties: colorless, transparent and easy-flowing liquid. Soluble in organic solvents, it will be hydrolyzed rapidly in contact with air to produce trimethylsilyl alcohol and hexamethyldisilane.
Application: hexamethyldisilazane can be used to exchange chlorine with chlorosilane monomer to obtain polysiloxane in organosilicon azane chemistry. This method has great advantages over the direct ammonia method in synthesis.
