CAS: 111-42-2
Alias: Diethanolamine, DEA
Molecular formula: C4H11NO2
Relative molecular mass: 105.13
1.Product Property
Diethanolamine is a colorless viscous liquid or crystalline solid with alkaline properties. It is hygroscopic and soluble in water and ethanol but sparingly soluble in benzene and ether. It can absorb gases like CO₂ and H₂S from the air.
2.Technical Norm
| Parameter | Specification |
| Appearance | Colorless viscous liquid or crystalline |
| Purity (DEA content) | ≥ 99% |
| Moisture content | ≤ 0.1% |
| Color (APHA) | ≤ 50 |
| Density (20°C) | 1.09-1.11 g/cm³ |
3.Application Scope and Usage
Diethanolamine is widely used as an absorbent for acid gases such as CO₂, H₂S, and SO₂. It serves as a raw material for the synthesis of herbicides like glyphosate and is used in the formulation of nonionic surfactants, emulsifiers, and lubricants. It is also employed in industrial gas purification and as an intermediate in organic synthesis.
4.Package and Storage
Diethanolamine is typically packaged in 200-liter steel drums or bulk containers. It should be stored in airtight containers in a dry, cool, and light-free environment to prevent moisture absorption and degradation. It is transported as a general chemical and should be handled with care to avoid exposure to air and light.
