  2. Tetramethyl orthosilicate - Wikipedia

    en.wikipedia.org/wiki/Tetramethyl_orthosilicate

    Tetramethyl orthosilicate (TMOS) is the chemical compound with the formula Si(OCH 3) 4.This molecule consists of four methoxy groups bonded to a silicon atom. The basic properties are similar to the more popular tetraethyl orthosilicate, which is usually preferred because the product of hydrolysis, ethanol, is less toxic than methanol.
