I need help: what are the requirements for trimethylchlorosilane regarding pipes, valves, and equipment?
I’m not familiar with this medium, but those containing chlorine are corrosive, so care should be taken to prevent corrosion. It is recommended to use fluorinated-lined pipes and valves, and the equipment should also be made of materials resistant to corrosion.
Can trimethylchlorosilane be condensed using a graphite condenser?
Fluorine lining is not necessary, but for valves, it’s best to use a bellows seal; otherwise, leakage will be severe!
I have no experience with trimethylchlorosilane, but I am familiar with dimethyldichlorosilane, methyltrichlorosilane, monomethylchlorosilane, tetraclorsilane, and trichlorosilane to a greater extent. Just thinking about trimethylchlorosilane and silicon tetrachloride gives me a headache – they’re extremely difficult to separate. Anyway, trimethylchlorosilane emits smoke when exposed to air or water (due to hydrolysis that produces HCl gas), so proper sealing is essential. As long as it is not leaked, pure chlorosilanes are not highly corrosive; ordinary carbon steel is sufficient for equipment and pipelines. Nothing special~ There’s no need to use graphite for the condenser; since the medium isn’t acidic, Q345R will suffice.
