Hexanoic acid (142-62-1)

?Hexanoic acid (CAS NO.142-62-1) is also named as 1-Hexanoic acid ; 1-Pentanecarboxylic acid ; 4-02-00-00917 (Beilstein Handbook Reference) ; AI3-07701 ; BRN 0773837 ; Butylacetic acid ; CCRIS 1347 ; Caproic acid ; Capronic acid ; Hexanoic acid (natural) ; Hexoic acid ; Kyselina kapronova ; Kyselina kapronova [Czech] ; NSC 8266 ; Pentanecarboxylic acid ; Pentiformic acid ; Pentylformic acid ; UNII-1F8SN134MX ; n-Caproic acid ; n-Hexanoic acid ; n-Hexoic acid ; n-Hexylic acid .?Hexanoic acid (CAS NO.142-62-1) is colourless liquid with an unpleasant odor. Contact may severely irritate skin, eyes and mucous membranes. May be toxic by ingestion, inhalation and skin absorption. 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. Flammable and/or toxic gases and heat are generated by the reaction of carboxylic acids with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides. 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. It is harmful if swallowed, inhaled, or absorbed through skin. Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.
