Stable under recommended storage conditions.
Possibility of hazardous reactions
A very dangerous fire hazard when exposed to heat, flame, or oxidizers.The vapour is heavier than air and may travel along the ground; distant ignition possible.DIETHYLAMINE is strongly alkaline. Incompatible with strong oxidizing agents and with strong acids. Violent reactions occur with sulfuric acid. Causes ignition on contact with cellulose nitrate. Explodes on contact with dicyanofurazan or dicyanofuroxan. Attacks some forms of plastics, rubber and coatings. (NTP, 1992)

Persistence and degradability
AEROBIC: Diethylamine, present at 100 mg/L, reached 69-89% of its Theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). In a screening study, diethylamine at 10 ppm degraded with both an activated sludge and freshwater/sediment inoculum, 59 and 38% of the Theoretical BOD was obtained after 12 days of incubation, respectively(2). Inhibition was noted at moderate concentrations and sizeable reductions in BOD were noted at 50 ppm(2). Diethylamine was degraded slowly by activated sludge even when acclimatized (53% of Theoretical BOD was achieved after 13 days)(3). However the concentration levels used in this study could not be ascertained. When added to stream water, the maximum rate of biodegradation of diethylamine was proportional to an initial amine concentration over a concentration range from several nanograms to several milligrams per liter(4). At the highest concentration studied, 10 mg/L, the half-life of diethylamine was 0.9 days(4).
Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for diethylamine(SRC), using a log Kow of 0.58(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).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of diethylamine can be estimated to be 27(SRC). According to a classification scheme(2), this estimated Koc value suggests that diethylamine is expected to have very high mobility in soil. The pKa of diethylamine is 11.09(3), indicating that this compound will exist entirely in cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
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.

Other Information
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered.Do NOT take working clothes home.
