General Manufacturing InformationSilane, chlorotriethyl-: ACTIVE
Applications
UsesChlorotriethylsilane 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.
UsesChlorotriethylsilane 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 DescriptionChlorotriethylsilane 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.
