trimethoxysilane usage and synthesis

chemical properties	colorless clear liquid
general description	a colorless liquid. slightly soluble in water and denser than water. hence floats on water. very toxic by ingestion, inhalation or skin absorption. may also be corrosive to skin and eyes.
air & water reactions	highly flammable. slightly soluble in water.
reactivity profile	trimethoxysilane may accumulate static electricity; hazardous polymerization may occur.
health hazard	may cause toxic effects if inhaled or ingested/swallowed. contact with substance may cause severe burns to skin and eyes. fire will produce irritating, corrosive and/or toxic gases. vapors may cause dizziness or suffocation. runoff from fire control or dilution water may cause pollution.
fire hazard	flammable/combustible material. may be 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.
