용도
Trimethylfluorosilane is used in the pharmaceutical and chemical industry.
제조 및 합성 방법
제조 방법
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).
