Chlorotriethylsilane Chemical Properties,Uses,Production
Chemical Properties
Clear transparent liquid
Chemical Properties
Chlorotriethylsilane is a readily sol most aprotic organic solvents, although CH2Cl2 is most commonly used; reacts with H2O and other protic solvents. It should be handled and stored under an anhydrous, inert atmosphere.
Application
Chlorotriethylsilane may be used as a derivatizing reagent for the determination of fluoride, in toothpaste samples using headspace solid-phase microextraction and gas chromatography–flame ionization detection.
Uses
Chlorotriethylsilane is used in the preparation of potent silylating agent and lewis acid catalyst. Chlorotriethylsilane derivatived ethers have been shown to be more stable towards hydrolysis than ar e trimethyl ethers.
Uses
Chlorotriethylsilane is used in laboratory chemicals. It is used for preparing silylating agent and acts as a catalyst for lewis acid. It is used for executing chemical reactions for silicon oil, silicon resin and polysiloxane. It is also used for eradicating robe agent, and used as protective agent and leather surface treating agent.
General Description
Chlorotriethylsilane may be used as a silylating reagent for the preparation of trisilyl ethers from alcohols in the presence of a base such as imidazole, pyridine or 4-(dimethylamino)pyridine. It is found to be more reactive when used with pyridine as a solvent.
reaction suitability
reagent type: derivatization reagent
reaction type: Silylations
