Diethylethanolamine[edit | edit source]
Diethylethanolamine (DEEA) is an organic compound with the chemical formula C6H15NO. It is a tertiary amine and an alcohol, characterized by the presence of both an amine group and a hydroxyl group in its structure. DEEA is a colorless liquid with a fishy odor, commonly used in various industrial applications.
Chemical Structure and Properties[edit | edit source]
Diethylethanolamine consists of a central nitrogen atom bonded to two ethyl groups and one ethanol group. The presence of the hydroxyl group makes it a versatile compound, capable of participating in hydrogen bonding. This property influences its solubility and reactivity.
Physical Properties[edit | edit source]
- Molecular Weight: 117.19 g/mol
- Density: 0.88 g/cm3
- Boiling Point: 161 °C
- Melting Point: -70 °C
- Solubility: Miscible with water and most organic solvents
Chemical Properties[edit | edit source]
Diethylethanolamine is a weak base due to the lone pair of electrons on the nitrogen atom. It can react with acids to form salts and can also participate in esterification reactions due to the presence of the hydroxyl group.
