Possibility of hazardous reactions
They will burn, though they may take some effort to ignite. /2,4,5-T amine, ester, or salt/2,4,5-T, N-BUTYL ESTER is an ester of a chlorinated organic acid. May react exothermically with acids to generate butyl alcohol and 2,4,5-trichlorophenoxyacetic. Strong oxidizing acids may cause a reaction that is sufficiently exothermic to ignite the reaction products. Heat may also be generated with caustic solutions.

Persistence and degradability

Bioaccumulative potential
No data on the bioconcentration of the n-butyl ester of 2,4,5-T could be found in the literature. From the log of its octanol/water partition coefficient, 4.8(1), one would estimate a log BCF of 3.43(2). Because of hydrolysis, this bioconcentration potential must be viewed as an upper limit(SRC).
Mobility in soil
Concentrations of 2,4-D and 2,4,5-T in soils and leachates ... were monitored for up to 28 months to characterize the patterns of herbicide mobility in soils under climatic conditions of the Palouse region of the Pacific Northwest (USA). ... Soils from Washington, Wyoming, or Mississippi ... treated with 1120 or 5600 kg/ha of a 1:1 mixture of 2,4-D and 2,4,5-T n-butyl esters in 1976, 1977, or 1978. The winter of 1976-1977 was mild and relatively dry, and little leachate could be collected. Subsequent winters were wet and the soil columns were saturated by the following springs. 2,4-D (< 1 ppm) was found in leachates from Washington and Wyoming soils receiving the herbicide application in 1976 or 1977 and > 30 ppm was found in leachates from Washington soil treated in 1978. 2,4-D (> 10 ppm) was found in leachates from the acidic Mississippi soil receiving high rate of herbicide application in 1977 or 1978. Concentrations of 2,4,5-T in the same leachates were higher for the Washington and Wyoming soils, but lower (than corresponding concentrations of 2,4-D) for the Mississippi soil. In all cases, 96-99% of the undegraded herbicides ... remained in the 0-10 cm soil layer after 2-3 winters, and only 0.14-1.65% of the 2,4,-D and 0.33-3.7% of the 2,4,5-T remaining ... were present in the 10-30 cm depths. Mobility characterization by soil TLC showed that the ester form of both herbicides was relatively immobile, the acid form was less mobile in the Mississippi soil than in Washington and Wyoming soils and 2,4-D was slightly more mobile than 2,4,5-T under corresponding conditions.

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.
