SECTION 10: Stability and reactivity

10.1 Reactivity

The substance may polymerize under the influence of light. Reacts with strong oxidants, bases and reducing agents.

10.2 Chemical stability

no data available

10.3 Possibility of hazardous reactions

Flammable liquid when exposed to heat or flame.The vapour is heavier than air.Ketones, such as PENTANE-2,4-DIONE, are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4. May dissolve plastics (USCG, 1999).

12.2 Persistence and degradability

AEROBIC: In a screening study using settled sewage seed at 20 deg C, 5.6, 40.0, 62.8, and 69.6 % of theoretical B.O.D. was determined after 5, 10, 15, and 20 incubation days, respectively(1).

12.3 Bioaccumulative potential

An estimated BCF of 3.2 was calculated in fish for acetyl acetone(SRC), using a log Kow of 0.40(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).

12.4 Mobility in soil

The Koc of acetyl acetone is estimated as 39(SRC), using a log Kow of 0.40(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that acetyl acetone is expected to have very high mobility in soil.

12.5 Other adverse effects

no data available

SECTION 13: Disposal considerations

13.1 Disposal methods

Product

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.
