propionic acid usage and synthesis

chemical properties	clear, colorless liquid
general description	a clear oily aqueous liquid with a pungent rancid odor. burns skin and the vapors irritate mucous membranes. corrosive to most metals and tissue. density 8.3 lb / gal.
air & water reactions	dilution with water causes release of heat.
reactivity profile	propionic acid reacts as an acid to neutralize bases in exothermic reactions. burns when exposed to heat, flame or oxidizers. when heated to decomposition emits acrid smoke and irritating fumes [lewis, 3rd ed., 1993, p. 1090].
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.
