Diethylamine

CAS No. 109-89-7

Formula: C4H11N
Basic Info

Diethylamine is a secondary amine with the molecular structure CH3CH2NHCH2CH3 (also written as C4H11N). It is a flammable, weakly alkaline liquid. It is miscible with water and ethanol. It is a colorless liquid which often appears brown due to impurities. It is volatile and has a strong unpleasant odor.
Diethylamine is manufactured from ethanol and ammonia and is obtained together with ethylamine and triethylamine. It is used as a corrosion inhibitor and in the production of rubber, resins, dyes and pharmaceuticals.
Diethylamine is a corrosive chemical and contact with skin may cause irritation or burns.
Diethylamine can be used to produce LSD and is strictly watched by the DEA.

12.1 Toxicity

  • Toxicity to fish: LC50; Species: Pimephales promelas (Fathead minnow) age 30 days; Conditions: flow through, 24.7°C, pH 7.71, dissolved oxygen 7.1 mg/L, hardness 48.5 mg/L CaCO3, alkalinity 49.5 mg/L CaCO3; Concentration: 855 mg/L for 96 hr /98% purity
  • Toxicity to daphnia and other aquatic invertebrates: LC50; Species: Daphnia magna (Water flea); Conditions: freshwater, renewal; Concentration: 56000 ug/L for 48 hr (95% confidence interval: 32000-100000 ug/L) /99% purity
  • Toxicity to algae: EC50; Species: Pseudokirchneriella subcapitata (Green algae); Conditions: freshwater, static; Concentration: 20000 ug/L for 96 hr; Effect: general growth
  • Toxicity to microorganisms: no data available

12.2 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).

12.3 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).

12.4 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).

12.5 Other adverse effects

no data available

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.
