Methods and materials for containment and cleaning up
Removal of phthalate esters (PAEs) by alpha-cyclodextrin (CD)-linked chitosan bead in aqueous solution was studied. Results of kinetic experiments indicated that diheptyl phthalate (DHpP) was adsorbed most efficiently (3.21 mg/g) ... It was concluded that the application of low cost alpha-CD-linked chitosan bead could have the potential to effectively remove PAEs from different aquatic environments.

SECTION 10: Stability and reactivity
Reactivity
Decomposes on burning. This produces irritating fumes.
Chemical stability
no data available
Possibility of hazardous reactions
DIHEPTYL PHTHALATE 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. Can generate electrostatic charges. [Handling Chemicals Safely 1980. p. 250].
Conditions to avoid

Incompatible materials

Hazardous decomposition products
When heated to decomposition it emits acrid smoke and irritating fumes.

Persistence and degradability
AEROBIC: Diheptyl phthalate present at 100 mg/L, reached 36% of its theoretical BOD in two weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1,4). Diheptyl phthalate, added to an aerobic semi-continuous activated sludge apparatus at 5, 10, and 20 mg/24 hr, underwent 52, 48, and 54% degradation, respectively(2-3). Di(heptyl,nonyl,undecyl) phthalate had a half-life of 6 to 8 days in river die-away tests(5). In active microcosms containing lake water and sediment, 40 to 48% of (14)C-di(heptyl,nonyl,undecyl) phthalate radioactivity was evolved as carbon dioxide over a 41 day period; after six weeks no residual (14)C-di(heptyl,nonyl,undecyl) phthalate was found in the water column and only 2 to 6% was associated with sediments(5). In semi-continuous activated sludge tests, a primary degradation half-life of <1 day at an addition rate of 5 to 200 mg/L per 24-hour cycle was observed for di(heptyl,nonyl,undecyl) phthalate(5). In shake flask studies using an acclimated bacterial inoculum, an ultimate degradation half-life of 5 days was observed for di(heptyl,nonyl,undecyl) phthalate at an initial concentration of 20 mg/L(5). Diheptyl phthalate was biodegraded in river water from the Kako River in Japan(6). Diheptyl phthalate was biodegraded 11-16% over a 40 day incubation period with activated sludge(7).
Bioaccumulative potential
BCFs of 0.9 to 2.2 and 6.2 to 16.7 were measured for diheptyl phthalate in carp at chemical concentrations of 1 and 0.1 mg/L, respectively(1). According to a classification scheme(2), these measured BCFs suggest that bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of diheptyl phthalate can be estimated to be 5.7X10+4(SRC). According to a classification scheme(2), this estimated Koc value suggests that diheptyl phthalate is expected to be immobile in soil. In sterile microcosms containing lake water and sediment, approximately 80% of di(heptyl,nonyl,undecyl) phthalate partitioned to sediment(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.
