SECTION 10: Stability and reactivity

Reactivity

no data available

Chemical stability

Shelf life of ester formulations varies, depending on the emulsifying system. Some retain satisfactory emulsifying properties after 3 yr. 2,4-D ester

Possibility of hazardous reactions

2,4-D, N-BUTYL ESTER is an ester. 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.

SECTION 12: Ecological information

Toxicity

  • Toxicity to fish: LC50 Bluegill 4.9 mg/l/24 hr; 3.7 mg/l/48 hr /Butyl ester, oil soluble formulation/ /Conditions of bioassay not specified
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

Persistence and degradability

Manometric evidence /was obtained/ that sewage microorganisms oxidized the alcohol moiety of ... butyl esters of 2,4-d. the 2,4-d was not decomposed during the 9-day incubation period. it was assumed that hydrolysis of the ester preceded oxidn of the alcohol moiety.

Bioaccumulative potential

An estimated BCF of 470 was calculated for 2,4-D butyl ester(SRC), using an estimated log Kow of 4.4(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC). However, 2,4-D butyl ester is readily hydrolyzed in fish and therefore should not bioconcentrate(4).

Mobility in soil

The Koc of 2,4-D butyl ester is estimated as 530(SRC), using a water solubility of 46 mg/l(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 2,4-D butyl ester is expected to have low mobility in soil(SRC). The adsorption of 2,4-D butyl ester to several Canadian prairie soils was attempted using slurries in a batch and soil column experiment(4). 2,4-D butyl ester hydrolyzed to the acid form with a half-life of 100 hr in the batch experiment and on contact in the column experiment(4). In the column experiment, 2,4-D butyl ester leached out essentially as the acid in about an hour(4). Thin layer chromatography resulted in 2,4-D butyl ester being characterized as immobile in soils from Washington, Wyoming, and Mississippi(5). 2,4-D butyl ester is absorbed on clay minerals in the following decreasing order bentonite, illite, and kaolinite(6). The sorbed amounts were very small as is evidenced by the fact that 8.77 g of bentonite, 13.33 g of illite, or 42.73 g of kaolinite are required to reduce the concentration of 2,4-D butyl ester from 3 to 2 mg/l(6). The adsorption of 2,4-D butyl ester to flocculated humic acid is stronger than the free acid and the adsorption follows Freundlich isotherm pattern with a slope of 0.97(7). Therefore, 2,4-D butyl ester will be adsorbed more strongly in soil containing humic materials than clayey soils(SRC).

Other adverse effects

no data available

SECTION 13: Disposal considerations

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.
