SECTION 10: Stability and reactivity

10.1Reactivity

The substance can presumably form explosive peroxides. Reacts with strong oxidants.

10.2Chemical stability

no data available

10.3Possibility of hazardous reactions

CombustibleEsters 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.

10.4Conditions to avoid

no data available

10.5Incompatible materials

Glycol ethers, glycols, ketones, and alcohols undergo violent decomposition in contact with 68-72% perchloric acid

10.6Hazardous decomposition products

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

SECTION 12: Ecological information

12.1Toxicity

• Toxicity to fish: LC50 - Danio rerio (previous name: Brachydanio rerio) - > 50 - < 70 mg/L - 96 h.
• Toxicity to daphnia and other aquatic invertebrates: LC50 - Daphnia magna - 664 mg/L - 48 h.
• Toxicity to algae: EC50 - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - 1 570 mg/L - 72 h.
• Toxicity to microorganisms: EC0 - activated sludge, industrial - 1 575 mg/L - 30 min. Remarks:Respiration rate.

12.2Persistence and degradability

AEROBIC: Diethyleneglycol monobutyl ether acetate, present at 100 mg/L, reached 100% of its theoretical BOD in four weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(1). A 20-day biodegradation study using 2.5 ppm diethyleneglycol monobutyl ether acetate in BOD bottle mineralization dilution water and settled sewage seed at 20 deg C gave a theoretical BOD of 67.6%(2). The normal BOD curve for diethyleneglycol monobutyl ether acetate seeded with microorganisms from domestic sewage shows slow development that usually requires more than five days for the BOD value to reach 20 percent of the theoretical oxygen demand (40% at 14 days)(3). Acclimated microorganisms from the Kanawana River biodegrade diethyleneglycol monobutyl ether acetate much faster with theoretical BOD values of 84% after 10 days and 58% after 10 days using microorganisms acclimated for 59 and 28 days, respectively(3). The difficulty in oxidizing diethyleneglycol monobutyl ether acetate is apparently related to the butoxy group(3). Diethyleneglycol monobutyl ether acetate had theoretical BOD rates of 13.3, 18.4, 24.6, and 67.0% for BOD 5, 10, 15, and 20 days, respectively(4).

12.3Bioaccumulative potential

An estimated BCF of 2 was calculated in fish for diethyleneglycol monobutyl ether acetate(SRC), using an estimated log Kow of 1.30(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).

12.4Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of diethyleneglycol monobutyl ether acetate can be estimated to be 10(SRC). According to a classification scheme(2), this estimated Koc value suggests that diethyleneglycol monobutyl ether acetate is expected to have very high mobility in soil(SRC).

12.5Other adverse effects

no data available

SECTION 13: Disposal considerations

13.1Disposal 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.
