SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating. This produces toxic and corrosive fumes including hydrogen chloride (see ICSC 0163).
Chemical stability
It is resistant to oxidation and hydrolysis under normal conditions.
Possibility of hazardous reactions
Noncombustible solidA halogenated benzoic 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 acids 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.

Persistence and degradability
microbial degradation may be one of the most important factors in persistence of dicamba in soil. A number of ... factors which are favorable for increased microbial activity ... reduced dicamba persistence. These ... were high organic matter content, adequate moisture, warm temperatures, and suitable pH. Persistence was increased in sterile soils ... soil actinomycete monocultures decarboxylated ((14)Carbon carboxyl)dicamba. Penicillium in the soil substrate enhanced decarboxylation, and evidence for secondary cooxidation reported.
Bioaccumulative potential
In an aquatic ecosystem study, dicamba did not bioaccumulate in algae, clam, crab, daphnia, elodea, mosquito fish, mosquito larvae or snail over a 32-day test period(1). An estimated BCF of 3 was calculated in fish for dicamba(SRC), using a log Kow of 2.21(2) and a regression-derived equation methodology(3). According to a classification scheme(4), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
Koc values of 7 to 21 (average of 13) were measured in five loam soils (organic matter content of 0.6 to 4.9%)(1). A Koc range of 7-34 was measured in six different Brazilian soils(2). According to a classification scheme(3), these Koc values suggest that dicamba is expected to have very high mobility in soil. Two literature reviews of dicamba adsorption and leaching in soil indicate that the herbicide is highly mobile in most soil types(4,5). The pKa of dicamba is 1.97(6), indicating that this compound will almost entirely exist 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(7).
Other adverse effects
no data available
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.
