SECTION 10: Stability and reactivity
10.1 Reactivity
Decomposes on heating. This produces toxic fumes. The solution in water is a medium strong base. Reacts violently with acids and oxidants.
10.2 Chemical stability
no data available
10.3 Possibility of hazardous reactions
The vapour is heavier than air.METHYLDIETHANOLAMINE is an aminoalcohol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. This compound may react with oxidizing materials. (NTP, 1992)

SECTION 12: Ecological information
12.1 Toxicity
- Toxicity to fish: LC50 - Leuciscus idus - 1 466 mg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - 233 mg/L - 48 h.

12.2 Persistence and degradability
AEROBIC: N-Methyldiethanolamine (present at 40% solution obtained from a gas sweetening plant) was found to be non-biodegradable after 28 days during a standard batch test using activated sludge from a municipal wastewater treatment plant as inoculum. In a 40-day continuous flow experiment using activated sludge, the same solution containing N-methyldiethanolamine degraded >96% based on TOC which was probably due to the adaptation of the microrganisms to the test substance(1). N-Methyldiethanolamine, added at daily increments of 15 mg/L, reached 40.0% of its BOD during a five day biochemical oxygen demand test using acclimated sewage culture(2).
12.3 Bioaccumulative potential
An estimated BCF of 3.2 was calculated for N-methyldiethanolamine(SRC), using an estimated log Kow of -1.50(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).
12.4 Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of N-methyldiethanolamine can be estimated to be 1 for the neutral species(SRC). According to a classification scheme(2), this estimated Koc value suggests that N-methyldiethanolamine is expected to have very high mobility in soil. The pKa of N-methyldiethanolamine is 8.52(3), indicating that this compound will partially exist in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).
12.5 Other adverse effects
no data available
SECTION 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.
