Methyltrichlorosilane Uses

Methyltrichlorosilane (CAS NO.75-79-6) is mainly used a precursor for forming various cross-linked siloxane polymers. Methyltrichlorosilane (CAS NO.75-79-6) is mainly used to form polymers such as poly(methylsilyne). Esters and lactones can also be cleaved with methyltrichlorosilane and sodium iodide to give the corresponding carboxylic acids . Acetals convert to carbonyl compounds.Thus, Methyltrichlorosilane (CAS NO.75-79-6)can be used to remove acetal protecting groups from carbonyl compounds under mild conditions. Finally, Methyltrichlorosilane (CAS NO.75-79-6) and sodium iodide can be used as a means of converting alcohols to their corresponding iodides.

Methyltrichlorosilane Production

Methyltrichlorosilane (CAS NO.75-79-6) results from the "direct reaction" of chloromethane with elemental silicon in the presence of a copper catalyst, usually at a temperature of at least 250 °C.
3 CH₃Cl + Si → CH₃SiCl₃ + C₂H₄ + H₂
While this reaction is currently the standard in industrial silicone production and is nearly identical to the first direct synthesis of methyltrichlorosilane, the overall process is inefficient with respect to methyltrichlorosilane.
