SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating and on burning. This produces toxic fumes and gases (phthalic anhydride - see ICSC 0315). Attacks some plastics.
Chemical stability
Stable to light
Possibility of hazardous reactions
CombustibleDIETHYL 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
no data available
Incompatible materials
May attack some forms of plastics.
Hazardous decomposition products
When heated to decomp it emits acrid smoke and irritating fumes.

Persistence and degradability
AEROBIC: The aerobic half-life of diethyl phthalate in natural fresh water was estimated as 3 days(1). Diethyl phthalate was found to degrade to ethyl methyl phthalate, dimethyl phthalate, methyl phthalate and ethyl phthalate when co-contaminated with methanol(2). A shake flask experiment using microorganisms isolated from a municipal sludge resulted in complete aerobic degradation of 400 mg/L of diethyl phthalate in approximately 35 hours, 200 mg/L in 25 hours, 140 mg/L in 22 hours and 75 mg/L in 18 hours(3). Diethyl phthalate was completely degraded by Rhine River water at 20 deg C in a 3 day die-away test(4). Diethyl phthalate was 87-92% degraded in 10-50 days at 25 deg C from a concn of 100 mg/L using 30 mg/L activated sludge(5). Electrolytic respirometer studies have shown that diethyl phthalate is readily biodegradable under aerobic conditions(6-8). Diethyl phthalate had aerobic aquatic half-lives of 0.39 days in a river die-away test, 4.33 days in MITI test, and 0.71 days using microcosm periphlton, and an aerobic soil half-life of 1.83 days agitated in aqueous suspension(9).
Bioaccumulative potential
Bluegill sunfish exposed to 9.42 ug/L of diethyl phthalate for 21 days had a measured BCF of 117(1). According to a classification scheme(2), this BCF value suggests that bioconcentration in aquatic organisms is high(SRC). An experimental log BCF of 2.07 was measured in clams(3).
Mobility in soil
A Koc value of diethyl phthalate of 1,726 was measured in podzol soil at pH 2.8 and 4.85% carbon, a value of 704 in alfisol soil at pH 6.7 and 1.25% carbon, a value of 320 in sediment at pH 7.1 and 1.58% carbon(1). An experimental log Koc of 1.99 was determined from unsaturated soil columns at pH 4.8(2). A Koc value of 69 was determined from measurements on soil samples from Broome County, NY(3). According to a classification scheme(4), these Koc values suggest that diethyl phthalate is expected to have low to high mobility 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.
