valeraldehyde usage and synthesis

chemical properties	colourless liquid
general description	a colorless liquid. slightly soluble in water and less dense than water. flash point 54°f. vapors heavier than air. used to make artificial flavorings and rubber.
air & water reactions	highly flammable. slightly soluble in water. valeraldehyde may be sensitive to prolonged exposure to air.
reactivity profile	valeraldehyde is an aldehyde. aldehydes are frequently involved in self-condensation or polymerization reactions. these reactions are exothermic; they are often catalyzed by acid. aldehydes are readily oxidized to give carboxylic acids. flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. these autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). the addition of stabilizers (antioxidants) to shipments of aldehydes retards autoxidation. valeraldehyde is incompatible with oxidizing agents, strong bases and strong reducing agents.
health hazard	vapor may irritate eyes. liquid irritates eyes and skin.
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.
