Anwendungen & Verwendung
Verwenden
Trimethylfluorosilane is used in the pharmaceutical and chemical industry.
Herstellung & Synthese
synthetische
Trimethylfluorosilane can be prepared from Chlorotrimethylsilane (TMSCl) by direct treatment with Hydrofluoric Acid. It can also be generated in situ by reaction of Ethyl Trimethylsilylacetate (ETSA) and Tetra-n-butylammonium Fluoride (TBAF).
