tetramethyl orthosilicate usage and synthesis

chemical properties	colorless transparent liquid
usage	used in the sol-gel synthesis of chromium-doped silicates1 and in the formation of hexagonal mesoporous silica layers.2
general description	a clear colorless liquid. flash point below 125°f. less dense than water and insoluble in water. very toxic by ingestion and inhalation and very irritating to skin and eyes. used to make paints and lacquers.
air & water reactions	flammable. insoluble in water.
reactivity profile	tetramethyl orthosilicate is incompatible with the following: oxidizers; hexafluorides of rhenium, molybdenum & tungsten .
health hazard	toxic; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. bromoacetates and chloroacetates are extremely irritating/lachrymators. reaction with water or moist air will release toxic, corrosive or flammable gases. reaction with water may generate much heat that will increase the concentration of fumes in the air. fire will produce irritating, corrosive and/or toxic gases. runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
fire hazard	highly flammable: will be easily ignited by heat, sparks or flames. vapors form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. most vapors are heavier than air. they will spread along ground and collect in low or confined areas (sewers, basements, tanks). vapors may travel to source of ignition and flash back. substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. contact with metals may evolve flammable hydrogen gas. containers may explode when heated or if contaminated with water.
