Tetraethyl orthosilicate Usage And Synthesis
Chemical Properties Colorless transparent liquid
Usage Commonly used as a precursor to prepare xerogel1,2
Usage Tetraethyl Orthosilicate is used in the preparation of antidreflective coatings on silicate glass via silicon dioxide. Crosslinking reagent.
General Description A clear colorless liquid with a faint odor. Flash point 125°F. Less dense than water. Vapors are heavier than air.
Air & Water Reactions Flammable. Practically insoluble in water. Reacts slowly with water to form silica and ethyl alcohol [Merck].
Reactivity Profile Tetraethyl orthosilicate reacts exothermically with acids Strong oxidizing acids may cause a reaction that is sufficiently exothermic to ignite the reaction products. May generate with caustic solutions. May generate flammable hydrogen with alkali metals and hydrides.
Health Hazard Inhalation of vapor causes eye and nose irritation, unsteadiness, tremors, salivation, respiratory difficulty, and unconsciousness. Contact with liquid irritates eyes and may cause dryness, cracking, and inflammation of skin. Ingestion may produce nausea, vomiting, and cramps.
Fire Hazard HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
