What is Chloromethyltriethoxysilane?
Description
(Chloromethyl)triethoxysilane is an organotrialkoxy silane based reagent with chloromethyl as the organofunctional group. It can be used as a starting material for the synthesis of silane based polymers.
Chloromethyltriethoxysilane is used Corresponding Grignard self-condenses to form polyfunctional carbosilanes.
Chemical properties
This silane presents as a colorless to slightly pale-yellow liquid. It is known to be slightly soluble in combustible solvents . Recommendations include storing in a tightly closed container in a cool, dark and well-ventilated place. For best results, it should also be kept under inert gas and protected from moisture. (Chloromethyl)triethoxysilane is incompatible with oxidizing agents. This chemical is flammable in liquid and vapor form and causes eye irritation.
The Uses of Chloromethyltriethoxysilane
(Chloromethyl)triethoxysilane uses and applications include: Used in polymers which serve as binders in adhesives and sealants; freezing agent of silicon sulfide rubber normal temps.; intermediate of silane coupling agents.
