What is an adipic acid?

ADIPIC 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 it 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. Behavior in Fire: Melts and may decompose to give volatile acidic vapors of valeric acid and other substances.

Where is adipic acid excreted?

Absorbed adipic acid is primarily excreted in the urine unchanged or in the breath of carbon dioxide.

How long does adipic acid react with hydroxyl radicals?

Vapor-phase adipic acid will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 2.9 days. Particulate-phase adipic acid will be removed from the atmosphere by wet and dry deposition.

How is adipic acid released into the atmosphere?

Adipic acid can be released into the environment via burning of biomass and motor exhaust. Adipic acid is a chemical constituent of tobacco smoke. Adipic acid is found in beet juice and tobacco and can be formed in the ambient atmosphere via photooxidation of olefins and hydrocarbons. If released to air, a vapor pressure of 2.27X10-7 mm Hg at 25 °C indicates adipic acid will exist in both the vapor and particulate phases in the atmosphere. Vapor-phase adipic acid will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 2.9 days. Particulate-phase adipic acid will be removed from the atmosphere by wet and dry deposition. If released to soil, adipic acid is expected to have very high mobility based upon an estimated Koc of 24. The pKa values of adipic acid are 4.44 and 5.44, indicating that this compound will exist almost entirely in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 1.8X10-12 atm-cu m/mole. Adipic acid is not expected to volatilize from dry soil surfaces based upon its vapor pressure. Biodegradation screening tests indicate that adipic acid is readily biodegradable in soil and water. A CO2 evolution of 84% was observed after 30 days aerobic incubation in a soil flask test. If released into water, adipic acid is not expected to adsorb to suspended solids and sediments in the water column based on its estimated Koc. Adipic acid was rapidly degraded in a river die-away test with 50% and 90% degradation being achieved in 3.5 and 7 days, respectively. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. An estimated BCF of 3 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions. Occupational exposure to adipic acid may occur through inhalation of dust particles and dermal contact with this compound at workplaces where adipic acid is produced or used. Monitoring and use data indicate that the general population may be exposed to adipic acid via inhalation of ambient air, ingestion of foods and dermal contact with consumer products containing adipic acid.

What is the rate constant of adipic acid?from pubchem.ncbi.nlm.nih.gov

The rate constant for the vapor-phase reaction of adipic acid with photochemically-produced hydroxyl radicals has been estimated as 5.6X10-12 cu cm/molecule-sec at 25 °C (SRC) using a structure estimation method (1). This corresponds to an atmospheric half-life of about 2.9 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm (1). The rate constant for the reaction of hydroxyl radicals in aqueous solutions at pH 2.0-2.2 is 2.0X10+9 L/mol-sec (2); this corresponds to an aquatic half-life of 1.1 years at an aquatic concentration of 1X10-17 hydroxyl radicals per liter (3).
