有机硅制作流程
From sand to Silicones: 1
The two starting materials for our processes are silicon
metal and methyl chloride
• Reduction of sand into silicon metal :
SiO2 + 2 C => Si + 2 CO
Sand (silica) Carbon Silicon Carbon monoxide
• Methyl chloride production :
CH3OH + HCl => CH3Cl + H2O
Methanol Hydrochloric acid Methyl Water
From sand to Silicones: 2
• Direct Process (Rochow) : Chlorosilanes
%
Si + CH3Cl => (CH3)2 Si Cl2 >50
Silicon Methyl chloride + CH3 Si Cl3 10 - 30
+ (CH3)3 Si Cl
