Possibility of hazardous reactions
CAPROIC 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. This compound reacts with bases, oxidizing agents and reducing agents. (NTP, 1992).

Persistence and degradability
AEROBIC: A 5-day theoretical BOD of 44% was observed for hexanoic acid in an aerobic screening test using a sewage inoculum(1). Five and 20-day theoretical BODs of 66 and 87% were observed in another aerobic screening test using a sewage inoculum(2). Using a Warburg respirometer, an adapted sewage inoculum and 10,000 ppm concns of hexanoic acid, respective 5-, 10- and 20-day theoretical BODs of 29, 66 and 69% were measured under aerobic conditions(3). One-day theoretical BODs of 26-54% were determined in a Warburg respirometer using various activate sludge inocula(4). Five-day theoretical BODs of 98-99% were achieved in an aerobic screening study using acclimated activated sludge inoculum(5). Respective 2-, 5-, 10- and 30-day theoretical BODs of 42, 48, 54 and 65% were measured in an aerobic Warburg respirometer study using sewage inoculum(6). Using a Warburg respirometer and activated sludge inocula from three Tennessee municipal plants, theoretical BODs of 34.9-61.2% were measured over a 3-day inoculation period(7).
Bioaccumulative potential
An estimated BCF of 3 was calculated for hexanoic acid(SRC), using a log Kow of 1.92(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).
Mobility in soil
Koc values of 26, 24 and 37 have been experimentally measured, for an acidic forest soil (pH 2.8, 4.85% organic carbon), agricultural soil (pH 6.7, 1.25% organic carbon), and a lake sediment (pH 7.1, 1.58% organic carbon), respectively(1). According to a classification scheme(2), these measured Koc values suggest that hexanoic acid is very highly mobile in soil(SRC). In addition, the pKa of hexanoic acid is 4.88(3), indicating that this compound will primarily exist as an anion in the environment, and anions generally possess high mobility in soil(4).

SECTION 13: Disposal considerations
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.
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.
