Inhalation of vapor irritates mucous membranes of the nose and lungs, causing coughing and sneezing. Contact with liquid irritates eyes and has a pronounced drying effect on the skin; may produce dermatitis. (USCG, 1999)

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep victim quiet and maintain normal body temperature. Obtain medical attention. Organic acids and related compounds

Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.

Behavior in Fire: Melts and may decompose to give volatile acidic vapors of valeric acid and other substances. Dust may form explosive mixture with air. (USCG, 1999)

Decomposes on heating. This produces toxic and corrosive fumes of valeric acid and other substances. The substance is a weak acid. Reacts with oxidizing materials.

Stable under recommended storage conditions.

Combustible when exposed to heat or flame ...Dust explosion possible if in powder or granular form, mixed with air. If dry, it can be charged electrostatically by swirling, pneumatic transport, pouring, etc.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.

The substance is irritating to the eyes and respiratory tract. Inhalation of the aerosol may cause asthmatic reactions. See Notes.

Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma.

Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

AEROBIC: Results of biological screening tests indicate that adipic acid is readily biodegradable(1). Adipic acid, present at 100 mg/L, reached 81% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(2). In study with 10 participating laboratories using OECD 301E (ready biodegradability test), all laboratories observed a ready biodegradability of adipic acid with a degradation of at least 86% and an average degradation of 96.6% after 19 days(1). In an aerobic modified Sturm test (CO2 evolution) according to OECD 301B guideline, adipic acid was degraded by 91% in terms of CO2 evolution after a period of 28 days(1). In a closed bottle test (OECD 301D), 83% of the adipic acid was degraded after 30 days(1). In a test according to the modified OECD screening test (OECD 301E), 96% (related to DOC) was degraded after a period of 19 days(1). In four biodegradability screening tests that were designed as models for degradability in surface water, the results ranged from 92% of theoretical BOD in 14 days to 83% in 30 days(3,4). In 5 tests designed to simulate treatment plants, results ranged from 99% DOC removal in 1 day to 92% of theoretical BOD in 14 days(3-5). In a systematic screening procedure after a 5-10 hr lag, 50-75% of theoretical BOD of adipic acid was obtained in 90-100 hr(6). Adipic acid was rapidly degraded in a river die-away test using Main River (Germany) water(5); 50% and 90% degradation being achieved in 3.5 and 7 days, respectively, at concentration levels of 700 mg/L(5). The Afnor test, which was designed to simulate degradation in polluted river water, gave a 5 day BOD of 36% of theoretical(7).

An estimated BCF of 3 was calculated in fish for adipic acid(SRC), using a log Kow of 0.08(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of adipic acid can be estimated to be 24(SRC). According to a classification scheme(2), this estimated Koc value suggests that adipic acid is expected to have very high mobility in soil. The pKa values of adipic acid's two acid groups are 4.44 and 5.44(3), indicating that this compound will exist almost entirely in the anion form and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.

The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort.Rest and medical observation are therefore essential.Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance.
