What is 2-(Butylamino)ethanol ?
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
The Uses of 2-(Butylamino)ethanol
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
