  10.3 Possibility of hazardous reactions

  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.

  Toxicity to microorganisms: no data available

  12.2 Persistence and degradability

  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).

  12.3 Bioaccumulative potential

  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).

  12.4 Mobility in soil

  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).

  12.5 Other adverse effects

  no data available

  13.Disposal considerations

  13.1 Disposal methods


  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.

  Contaminated packaging

  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.
