SECTION 10: Stability and reactivity

10.1Reactivity

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

10.2Chemical stability

no data available

10.3Possibility of hazardous reactions

CombustibleA violent explosion occurred when lithium aluminum hydride was being used to dry diethylene glycol dimethyl ether. The ignition may have occurred due to the presence of large amounts of water or perhaps peroxide formed in the ether. About 75% of the ether had been removed when the explosion occurred, [MCA Case History 1494 (1968)].

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 toxic fumes of /nitrogen oxides/.

SECTION 11: Toxicological information

• Oral: LD50 Mouse oral 2978 mg/kg bw
• Inhalation: LC50 Rat inhalation >11 mg/L/7 hr
• Dermal: no data available

Skin corrosion/irritation

no data available

Serious eye damage/irritation

no data available

Respiratory or skin sensitization

no data available

Germ cell mutagenicity

no data available

Carcinogenicity

no data available

Reproductive toxicity

no data available

STOT-single exposure

The substance is mildly irritating to the eyes, skin and respiratory tract.

STOT-repeated exposure

Animal tests show that this substance possibly causes toxicity to human reproduction or development.

Aspiration hazard

A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.

SECTION 12: Ecological information

12.1Toxicity

• Toxicity to fish: no data available
• Toxicity to daphnia and other aquatic invertebrates: no data available
• Toxicity to algae: no data available
• Toxicity to microorganisms: no data available

12.2Persistence and degradability

AEROBIC: Diethylene glycol dimethyl ether had a 37.0% COD removal at 30 deg C from a starting concentration of 600 mg COD/L (time period not given) indicating little degradation compared to 95% degradation of ethylene glycol monophenyl ether(1). Diethylene glycol dimethyl ether was degraded 33% after 25 days and a 7 day lag period using an activated sludge from an industry producing the chemical(2). 40% was removed in a 1% salt solution after 25 days with a 20 day lag period, higher salt concentrations inhibited the degradation of diethylene glycol dimethyl ether(2).

12.3Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for diethylene glycol dimethyl ether(SRC), using a log Kow of -0.36(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

The Koc of diethylene glycol dimethyl ether is estimated as 15(SRC), using a log Kow of -0.36(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that diethylene glycol dimethyl ether is expected to have very high mobility in soil.

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.
