10.1 Reactivity

no data available

10.2 Chemical stability

Stable under recommended storage conditions.

10.3 Possibility of hazardous reactions

CombustibleKetones, such as BENZOPHENONE, 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. This compound can react with oxidizing materials.

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: EC50; Species: Pimephales promelas (fathead minnow); Conditions: flow-through bioassay with measured concentrations, 25.3°C, dissolved oxygen 6.9 mg/L, hardness 47.9 mg/L calcium carbonate, alkalinity 34.0 mg/L calcium carbonate, and pH 7.72; Concentration: 15.3 mg/L for 96 hr (confidence limit: 14.4-16.3 mg/L); Effect: loss of equilibrium
  • Toxicity to daphnia and other aquatic invertebrates: EC50; Species: Daphnia magna (Water flea); Conditions: freshwater; static; Concentration: 280 ug/L (95% confidence limit: 210 to 370 ug/L) for 1 day; Effect: intoxication, immobile /active ingredient
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Benzophenone, present at 100 mg/L, reached 0% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). In a separate screening test, benzophenone reached 12% of its theoretical BOD over an incubation period of 5 days using a sewage sludge inoculum(2). The removal of benzophenone from soil columns treated with feed solutions containing 5.8X10-5, 1.3X10-4, 1.1X10-4, and 2X10-3 ppm benzophenone was 15, 41, 45, and 40%, respectively(3). An increase in the column effluent concentration of benzophenone after mercuric chloride was added to the feed solution indicated that some biodegradation took place in the soil column(3).

12.3 Bioaccumulative potential

BCF values of 3.4-9.2 were measured using carp (Cyprinus carpio) which were exposed to benzophenone concentrations of 0.3 ppm over an 6-week period(1). According to a classification scheme(2), this BCF range suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

The Kd for benzophenone was measured to be 2.71 on a red earth soil from Australia with an organic matter content of 1.09%(1), corresponding to a Koc of about 430(SRC). The average Koc value from three soils was measured to be 517(2). According to a classification scheme(3), these Koc values suggest that benzophenone is expected to have moderate to low mobility in soil. Benzophenone was detected (concentration below 0.500 ug/L) in both the treated effluent applied at the top of a 2.4 m long, 32.5 cm diameter soil column and in the drainage collected from the bottom of the column after 23 days(4).

12.5 Other adverse effects

no data available

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.

Contaminated packaging

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.
