msds information

isobutyric acid usage and synthesis

chemical properties	clear colorless liquid
general description	a colorless liquid with a light odor of rancid butter. flash point 132°f. density 7.9 lb / gal. corrosive to metals and tissue.
air & water reactions	flammable. water soluble
reactivity profile	isobutyric acid corrodes aluminum and other metals. flammable hydrogen gas may accumulate in enclosed spaces in which this reaction has taken place [uscg, 1999].
health hazard	inhalation causes irritation of nose and throat. ingestion causes irritation of mouth and stomach. contact with eyes or skin causes irritation.
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.
