Triethoxysilane Chemical Properties,Uses,Production

Description

Triethoxysilane is an organosilicon compound with the formula HSi(OC2H5)3. It is a colourless liquid used in precious metal-catalysed hydrosilylation reactions. The resulting triethoxysilyl groups are often valued for attachment to silica surfaces.Compared to most compounds with Si-H bonds, triethoxysilane exhibits relatively low reactivity. Like most silyl ethers, triethoxysilane is susceptible to hydrolysis. As reducing agent, triethoxysilane can for example be used in reduction of amides, reduction of carbonyl compounds in the presence of cobalt(II) chloride as catalyst, Cu-catalyzed reductive hydroxymethylation of styrenes, and Rh-catalyzed hydrodediazoniation.?

Chemical Properties

Colorless, clear liquid

Physical properties

bp 134–135 °C; d 0.89 g cm?3.

Uses

Triethoxysilane is useful reagent for the hydrosilylation of carbon–carbon multiple bonds; reducing agent for carbonyl groups

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.
