SECTION 10: Stability and reactivity

10.1Reactivity

On combustion, forms toxic gases. Reacts with strong acids, strong bases and strong oxidants.

10.2Chemical stability

no data available

10.3Possibility of hazardous reactions

CombustibleEthers, such as TRIETHYLENE GLYCOL METHYL ETHER, can act as bases. They form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert.

10.4Conditions to avoid

no data available

• Toxicity to microorganisms: EC0 - activated sludge, industrial - > 2 000 mg/L - 30 min. Remarks:Respiration rate.

12.2Persistence and degradability

AEROBIC: Triethylene glycol monomethyl ether has 10 and 20 day theoretical BOD values of 14 and 23, respectively(1). A study using activated sludge gave a degradation rate for diethylene glycol monoethyl ether of 0.22/hour(2) giving a half-life of 3.2 hours(SRC).

12.3Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for triethylene glycol monomethyl ether(SRC), using an estimated log Kow of -1.46(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 triethylene glycol monomethyl ether can be estimated to be 10(SRC). According to a classification scheme(2), this estimated Koc value suggests that triethylene glycol monomethyl ether 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.
