Methyltrichlorosilane

Methyltrichlorosilane is a chemical compound with the formula CH3SiCl3. It is a colorless liquid with a sharp odor similar to that of hydrochloric acid. As methyltrichlorosilane is a chlorosilane, it is a potent methylating agent.

Production

Methyltrichlorosilane is produced on an industrial scale from silicon and methyl chloride. The reaction is catalyzed by a mixture of copper and copper(I) chloride.

Uses

Methyltrichlorosilane is used in the production of silicone polymers or silicone resins. It is also used as a component in the production of room-temperature vulcanizing (RTV) silicones, a type of silicone rubber that cures at room temperature.

Safety

Methyltrichlorosilane is a highly reactive compound and should be handled with care. It reacts violently with water to produce hydrochloric acid and a methylsilanol, which can cause severe burns and eye damage. It is also harmful if inhaled, causing respiratory irritation.
