Triethoxysilane Chemical Properties,Usage,Production

  • Chemical Properties Colorless, clear liquid
  • General Description Liquid. Used as a reducing agent.
  • Air & Water Reactions May become pyrophoric, by generation of silane
  • Reactivity Profile Triethoxysilane has been involved in cases where Triethoxysilane has disproportionated, generating silane (SiH4) which has a history of being pyrophoric.
  • Health Hazard Toxicity is similar to silanes. Silanes are moderately irritating to skin, eyes, and mucous membranes. Silane compounds are toxic.
  • Fire Hazard When heated to decomposition, Triethoxysilane emits acrid smoke and fumes.
  • Safety Profile Poison by intravenous route.Moderately toxic by inhalation. Flammable liquid. Whenheated to decomposition it emits acrid smoke andirritating fumes.
  • Purification Methods Fractionate it using a column packed with glass helices of ca 15 theoretical plates in an inert atmosphere. Store it in aliquots in sealed ampoules because it is sensitive to moisture. [Spauschus et al. J Am Chem Soc 72 1377 1950, MacKenzie et al. J Am Chem Soc 72 2032 1950, Havill et al.
