Possibility of hazardous reactions
Organophosphates, such as 2-ETHYLHEXYL DIPHENYL PHOSPHATE, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides
Conditions to avoid
no data available
Incompatible materials
Incompatible materials: Strong oxidizing agents
Hazardous decomposition products
When heated to decomposition it emits toxic fumes of PO(x) /phosphorus oxides/.

Persistence and degradability
AEROBIC: In river die-away biodegradation studies using Mississippi River water, diphenyl-2-ethylhexyl phosphate, at an initial concentration of 1 ug/L, underwent approximately 90% removal in 5 days(1). In semi-continuous activated sludge (SCAS) biodegradation test using an activated sludge seed, diphenyl-2-ethylhexyl phosphate, at a feed rate of 3 mg/day using a weekly addition cycle, underwent 74% biodegradation over a 22 week testing period(1). In river die-away biodegradation studies using Mississippi River water, diphenyl-2-ethylhexyl phosphate underwent 84-99% primary degradation as indicated by chemical analysis and 56-68% ultimate biodegradation as indicated by measuring CO2 evolution(2). In lake water/sediment microcosm biodegradation studies, diphenyl-2-ethylhexyl phosphate underwent 5-24% ultimate biodegradation (time not stated)(2). The biodegradation half-lives for diphenyl-2-ethylhexyl phosphate in water/sediment system obtained from the Red River, Manitoba, and an eutrophic farm pond were 5.3 days and 4.5 days, respectively at 25 deg C; biodegradation was only slightly slower under anaerobic conditions(3). Diphenyl-2-ethylhexyl phosphate, present at 100 mg/L, reached 1% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(4).
Bioaccumulative potential
BCFs of 433-735 and 194-426 were reported in carp (Cyprinus carpio) which were exposed to diphenyl-2-ethylhexyl phosphate at 0.1 and 0.01 mg/L, respectively, over an 8-week period(1). An experimental bioconcentration factor in rainbow trout for diphenyl-2-ethylhexyl phosphate, obtained in outdoor experiments performed in small, artificial ponds 10 hr post-treatment, was 170(2). In rainbow trout fry (Salmo gairdneri), BCFs of 1147 and 1481 were reported after respective, 50 and 5 ug/L diphenyl-2-ethylhexyl phosphate exposure in a static system for 24 hours(3). According to a classification scheme(4), these BCFs suggest bioconcentration in aquatic organisms is high to very high(SRC). In outdoor experiments performed in small, artificial ponds, where the initial concentration of diphenyl-2-ethylhexyl phosphate was 50 ug/L, 1% to 2% of the amount applied was found to bioconcentrate in fathead minnows 18 hrs after application which decreased to 0.1% to 0.3% of the amount originally applied after 105 days(5).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of diphenyl-2-ethylhexyl phosphate can be estimated to be 32,200(SRC). According to a classification scheme(2), this estimated Koc value suggests that diphenyl-2-ethylhexyl phosphate is expected to be immobile in soil. In outdoor experiments performed in small, artificial ponds, 62% of the applied diphenyl-2-ethylhexyl phosphate was found adsorbed to sediment after 1 hr; 24% of the amount originally applied was adsorbed after 360 days(3).
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.
