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.
