摘要： In an extraction process for isolating trimethoxysilane (TMS) from a TMS/methanol mixture by formation of two phases, namely a TMS-rich extract phase and a methanol-rich raffinate phase, by addition of one or more methanol-soluble inorganic and/or organic salts and, if desired, an additional nonpolar organic solvent and subsequent phase separation, the amount of salt added is selected so that the weight ratio of trimethoxysilane to methanol in the extract phase is at least 94% by weight:6% by weight (normalized to 100% by weight). The use of one or more inorganic salts in an extraction process for isolating trimethoxysilane from a trimethoxysilane/methanol mixture is also claimed.
