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

CombustibleDIETHYLENE GLYCOL MONOMETHYL ETHER is a ether-alcohol derivative. The ether being relatively unreactive. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert alcohols to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.

10.4Conditions to avoid

no data available

10.5Incompatible materials

Contact of the solid hypochlorite with glycerol, diethylene glycol monomethyl ether or phenol causes ignition within a few min, accompanied by irritant smoke, especially with phenol (formation of chlorophenols).

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 - Pimephales promelas - 5 741 mg/L - 96 h.
• Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - 1 192 mg/L - 48 h.
• Toxicity to algae: EC50 - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - > 1 000 mg/L - 96 h.
• Toxicity to microorganisms: EC20 - activated sludge, domestic - > 1 000 mg/L - 30 min.

12.2Persistence and degradability

AEROBIC: Aerobic biological screening studies, which utilized settled waste water, sewage or activated sludge for inoculum, have demonstrated that diethylene glycol monomethyl ether should biodegrade in the environment(1-5). Diethylene glycol monomethyl ether showed losses of 0, 21, and 66% of the theoretical BOD when incubated at 20 deg C for 5, 10, and 20 days, respectively(1). Other 5 day BOD tests at 20 deg C, resulted in the loss of 5%(2) and 9%(3) of the theoretical BOD. A study using activated sludge gave a degradation rate for diethylene glycol monomethyl ether of 0.26/hour(4) giving a half-life of 2.7 hours(SRC). Biodegradation half-lives of 2-16 days have been reported for diethylene glycol monomethyl ether(5).

12.3Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for diethylene glycol monomethyl ether(SRC), using an estimated log Kow of -1.18 and a regression-derived equation(1). According to a classification scheme(2), 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 diethylene glycol monomethyl ether can be estimated to be 1(SRC). According to a classification scheme(2), this estimated Koc value suggests that diethylene glycol monomethyl 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.
