hexanoic acid usage and synthesis

chemical properties	colourless liquid
usage	intermediates of liquid crystals
general description	a white crystalline solid or colorless to light yellow solution with an unpleasant odor. insoluble to slightly soluble in water and less dense than water. contact may severely irritate skin, eyes and mucous membranes. may be toxic by ingestion, inhalation and skin absorption. used to make perfumes.
air & water reactions	slightly water soluble.
reactivity profile	hexanoic acid is a carboxylic acid. carboxylic acids donate hydrogen ions if a base is present to accept them. they react in this way with all bases, both organic (for example, the amines) and inorganic. their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat. neutralization between an acid and a base produces water plus a salt. carboxylic acids with six or fewer carbon atoms are freely or moderately soluble in water; those with more than six carbons are slightly soluble in water. soluble carboxylic acid dissociate to an extent in water to yield hydrogen ions. the ph of solutions of carboxylic acids is therefore less than 7.0. many insoluble carboxylic acids react rapidly with aqueous solutions containing a chemical base and dissolve as the neutralization generates a soluble salt. carboxylic acids in aqueous solution and liquid or molten carboxylic acids can react with active metals to form gaseous hydrogen and a metal salt. such reactions occur in principle for solid carboxylic acids as well, but are slow if the solid acid remains dry. even "insoluble" carboxylic acids may absorb enough water from the air and dissolve sufficiently in hexanoic acid to corrode or dissolve iron, steel, and aluminum parts and containers. carboxylic acids, like other acids, react with cyanide salts to generate gaseous hydrogen cyanide. the reaction is slower for dry, solid carboxylic acids. insoluble carboxylic acids react with solutions of cyanides to cause the release of gaseous hydrogen cyanide. flammable and/or toxic gases and heat are generated by the reaction of carboxylic acids with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides. carboxylic acids, especially in aqueous solution, also react with sulfites, nitrites, thiosulfates (to give h2s and so3), dithionites (so2), to generate flammable and/or toxic gases and heat. their reaction with carbonates and bicarbonates generates a harmless gas (carbon dioxide) but still heat. like other organic compounds, carboxylic acids can be oxidized by strong oxidizing agents and reduced by strong reducing agents. these reactions generate heat. a wide variety of products is possible. like other acids, carboxylic acids may initiate polymerization reactions; like other acids, they often catalyze (increase the rate of) chemical reactions. hexanoic acid reacts with bases, oxidizing agents and reducing agents. .
health hazard	harmful if swallowed, inhaled, or absorbed through skin. material is extremely destructive to tissue of mucous membranes and upper respiratory tract, eyes and skin. inhalation may be fatal as a result of spasm, inflammation and edema of the larynx and bronchia, chemical pneumonitis and pulmonary edema. symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.
fire hazard	special hazards of combustion products: irritating vapor may be generated.
