10.3 Possibility of hazardous reactions
Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.

12.2 Persistence and degradability
AEROBIC: 2,4-D isooctyl ester could not be degraded by activated sewage acclimated with 2,4-D in a laboratory test(1). In soil, the hydrolysis of 2,4-D isooctyl ester to 2,4-D and the alcohol was suggested to be microbially mediated(2). 2,4-D isooctyl ester was not detected after 3 years at an initial concentration of 560 ppm and application rate of 1,280 kg/ha(2).17.8% and 3.6% of 2,4-D isooctyl ester, applied at a rate of 4,480 kg/ha (initial residue concn of 2,640 ppm), was recovered after 3 and 6 years, respectively(2). When the ester was incubated in a silt loam soil for 10 weeks at a concn up to 16 ppm, more than 60% was mineralized (based on carbon content) into CO2(3); less than 2% of the applied ester was found undegraded in soil as 2,4-D(3); over 20% of the carbon was incorporated into the soil probably as new biomass(3).
12.3 Bioaccumulative potential
An estimated BCF of 31,000 was calculated for 2,4-D isooctyl ester(SRC), using an estimated log Kow of 6.7(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is very high(SRC). However, like 2,4-D butyl ester, 2,4-D isopropyl ester may also be readily metabolized in fish and therefore should not bioconcentrate(4).
12.4 Mobility in soil
The Koc of 2,4-D isooctyl ester is estimated as 29,000(SRC), using a water solubility of 0.0324 mg/l(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 2,4-D isooctyl ester is expected to be immobile in soil(SRC). 2,4-D isooctyl ester is adsorbed slightly by clay minerals with adsorption to bentonite > illite > kaolinite(4). Large amounts, eg 10.31, 14.16, and 44.63 grams, respectively, would be required to reduce the concentration of 2,4-D isooctyl ester in water from 3 mg/l to 2 mg/l(4). However, the adsorption of 2,4-D isooctyl ester was much greater for soils with high organic carbon than soils with high content of clay(5).
12.5 Other adverse effects
no data available
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.
