Chemical stability

Possibility of hazardous reactions
DIUNDECYL PHTHALATE reacts 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 interaction with caustic solutions. Flammable hydrogen is generated by mixing with alkali metals and hydrides. Can generate electrostatic charges [Handling Chemicals Safely, 1980. p. 250].
Conditions to avoid

Incompatible materials
no data available
Hazardous decomposition products
When heated to decomp it emits acrid smoke and irritating fumes.

Persistence and degradability
AEROBIC: In an acclimated shake flask CO2 evolution test, in which loss of parent compound (primary degradation) as well as CO2 evolution (ultimate degradation) was measured using an inoculum prepared from soil and sewage, >99% of diundecyl phthalate was lost and 76% of theoretical CO2 was evolved after 28 days(1). The biodegradation half-life was 6.17 days with a 2.7 day lag(1). Results of a semi-continuous activated sludge test, a test which simulates that of a treatment plant, were 45 and 29% removal of the diundecyl phthalate at 5 and 20 mg/day feed rates(2-3). At the lower feed rate the half-life was 2.7 days(2). Since the ester exhibited no inhibitory effects on the sludge growth rate, the decreased degradation at higher concentration levels is attributed to its low water solubility(2). Diundecyl phthalate at a concentration of 1 ppm had a half-life of 2.5 weeks in a river die-away test using Mississippi River water(2). Di(heptyl,nonyl,undecyl) phthalate had a half-life of 6 to 8 days in river die-away tests(4). 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(4). 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(4). In shake flask studies using an acclimated bacterial inoculum, an ultimate biodegradation half-life of 5 days was observed for di(heptyl,nonyl,undecyl) phthalate at an initial concentration of 20 mg/L(4). Diundecyl phthalate was biodegraded 10% in 7 days in river water(5). Diundecyl phthalate was biodegraded 57% from an initial concentration of 46 ppm using a semi-continuous activated sludge for 28 days(6).
Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for diundecyl phthalate(SRC), using an estimated log Kow of 11.49(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of diundecyl phthalate can be estimated to be 7.7X10+6(SRC). According to a classification scheme(2), this estimated Koc value suggests that diundecyl phthalate is expected to be immobile in soil.
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.
