2-(Butylamino)ethanol Chemical Properties, Uses, Production
Description
2-(butylamino)ethanol (BAE) is a secondary amine and has steric hindrance with a strong tendency to form bicarbonate on reaction with CO2. As a result, equilibrium CO2 loading can exceed 0.5 mol CO2/mol amine, resulting in higher cyclic capacity than conventional MEA. BAE's hydrophobicity is very high and highly soluble with most amines and ethers. The advantages of preferring BAE over traditional 2-amino-2-methyl-1-propanol (AMP) are that BAE does not produce solid precipitation on CO2 loading, CO2 absorption and reaction rate of BAE is higher than AMP, it can be regenerated at low temperature, low heat of CO2 absorption and BAE is cheaper than AMP[1].
Chemical Properties
Colorless liquid
Uses
2-(Butylamino)ethanol (N-Butylethanolamine) may be employed for the synthesis of 4-alkylamino-2,5,6-trimethyl -7-(2,4,6-trimethylphenyl)pyrrolo[2,3-d]pyrimidines and N-butyl-N-(2-nitroxyethyl)nitramine (BuNENA).
General Description
2-(Butylamino)ethanol is a secondary amine having a -OH group.
Safety Profile
Moderately toxic by ingestion and intraperitoneal routes. A skin and severe eye irritant. See also AMINES. Combustible when exposed to heat or flame. To fight fire, use alcohol foam, foam, Con, dry chemical. Incompatible with oxihzing materials. When heated to decomposition it emits toxic fumes of NOx
Synthesis
To a solution of 3-aminopropan-1-ol (1.0 g, 13.3 mmol) and propionaldehyde (0.77 g, 13.3 mmol) in MeOH (20 mL) was added MgSO4 (6.4 g, 53.3 mmol). The reaction mixture was stirred at 25 C for 12 h. The undissolved material was filtered and the filtrate was treated with NaBH4 (556 mg, 14.6 mmol) under an ice bath. The mixture was then stirred at 25 C for 1 hour. The reaction solution was concentrated in vacuum and the residue was dissolved in DCM (100 mL) and stirred for 5 min. The undissolved material was filtered and the filtrate was concentrated in vacuum to give 2-butylaminoethanol (1.0 g, 64.1%) as a yellow oil.
Toxics Screening Level
The Initial Risk Screening Level (ITSL) for 2-Butylaminoethanol is 4 μg/m3 based on annual averaging time.
