Production
2-Ethylhexanoic acid is produced industrially from propylene, which is hydroformylated to give butyraldehyde.
Aldol condensation of the aldehyde gives 2-ethylhexenal, which is hydrogenated to 2-ethylhexanal.
Oxidation of this aldehyde gives the carboxylic acid
2-Ethylhexanoic acid Chemical Properties,Uses,Production
Chemical Properties: colourless liquid
Uses: Paint and varnish driers (metallic salts). Ethylhexoates of light metals are used to convert some mineral oils to greases. Its esters are used as plasticizers.
General Description
2-Ethylhexanoic acid is a colorless to light yellow liquid with a mild odor. 2-Ethylhexanoic acid will burn though 2-Ethylhexanoic acid may take some effort to ignite.
2-Ethylhexanoic acid is slightly soluble in water. 2-Ethylhexanoic acid is corrosive to metals and tissue. 2-Ethylhexanoic acid is used to make paint dryers and plasticizers.
Reactivity Profile
2-Ethylhexanoic 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 2-Ethylhexanoic 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.
Health Hazard: Harmful if swallowed, inhaled or absorbed through skin. Material is extremely destructive to tissues 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, bronchii, chemical pneumonitis and pulmonary edema. Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.
Fire Hazard: 2-Ethylhexanoic acid is combustible.
2-Ethylhexanoic acid forms compounds with metal cations that have stoichiometry as metal acetates.
IUPAC name: 2-Ethylhexanoic acid
CAS Number: 149-57-5
2-Ethylhexanoic Acid is a colorless, high boiling liquid having a mild odor.
