Trimethylfluorosilane Usage And Synthesis

Chemical Properties	Clear liquid
Uses	Trimethylfluorosilane is used in the pharmaceutical and chemical industry.
Purification Methods	It is a FLAMMABLE gas which is purified by fractional distillation through a column at low temperature and with the exclusion of air [Booth & Suttle J Am Chem Soc 68 2658 1946, Reid & Wilkins J Chem Soc 4029 1955]. [Beilstein 4 IV 4007.]
