10.3 Possibility of hazardous reactions

Technical acid /is/ nonflammable.A halogenated organic acid derivative. 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 polymer

12.2 Persistence and degradability

AEROBIC: Half-lives for biodegradation of 2,4,5-TP in three Saskatchewan, Canada prairie soils were 13, 13 and 10 days for heavy clay loam, clay loam and sandy loam, respectively(1). Negligible degradation was observed in air-dried soils(1). Biodegradation of 2,4,5-TP was tested in Mardin, Honeoye and Dunkirk silt loam soil samples from areas in NY, resulting in complete disappearance in greater than 47, 124 and 205 days, respectively(2). 2,4,5-TP was shown to have an aerobic half-life of 16 days in soil(5). 2,4,5-Trichlorophenol has been identified as a product of the biodegradation of 2,4,5-TP(6). 2,4,5-TP was shown to have a half-life of 8 and 10 days in sandy loam, 15 and 21 days in forest soil, 13 days in clay loam and 14 days in grassland soil(7). In soil, 2,4,5-TP was reported to degrade more slowly than 2,4-D(8). No biodegradation of 2,4,5-TP was observed after 50 days incubation in Hamilton Harbour water from Ontario, Canada(3). An initial concn of 2,4,5-TP of 107.5 ppm was completely degraded in lagoon water in 9 days after 100 ml of 2,4,5-trichlorophenol acclimated water was added and incubated at 20 to 21°C with constant aeration(4). 2,4,5-TP, incubated at 25°C with sewage sludge in an aeration tank for 47 days gave an unchanged concentration of the S enantiomer and a 40% decrease in the R enantiomer(9).

12.3 Bioaccumulative potential

A BCF of 58 was reported in fish in flowing water for 2,4,5-TP(1). According to a classification scheme(2), this BCF data suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). 2,4,5-TP does not appear to bioconcentrate more than 10 fold(3).

12.4 Mobility in soil

Log Koc values for 2,4,5-TP have been reported as 1.87 and 2.03(1), giving Koc values of 74 and 107. According to a classification scheme(2), these Koc values suggest that 2,4,5-TP will have high mobility in soil(SRC). 2,4,5-TP had sorption values of 2.7-5.9 mg/kg at different conditions in soil with a pH of 7.4, and sorption values of 0.2-1.1 mg/kg in soil with a pH of 8.2(3). 2,4,5-TP had reported sorption coefficients of 308-9016 mL/g(4). 2,4,5-TP is expected to be negatively charged and will not be readily absorbed making it more mobile in soil(5). The pKa of 2,4,5-TP is 2.84(6), indicating that this compound will exist almost entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(7).

12.5 Other adverse effects

13.Disposal considerations

13.1 Disposal methods

Product

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.
