[Triethanolamine supply] List of specific physical property data of triethanolamine

Image keywords

It is understood that triethanolamine is a colorless, transparent and viscous liquid at room temperature, with a slight ammonia smell. It is hygroscopic and can absorb moisture and carbon dioxide in the air. Can be freely mixed with water and alcohol, soluble in chloroform, slightly soluble in benzene and ether. The pH of 0.1moI/L solution is 10.5. There is a danger of burning when exposed to high heat, open flame or contact with oxidants. Its aqueous solution is corrosive.

The specific physical property data of triethanolamine are as follows:

1. Properties: colorless oily liquid or white solid, with a slight smell of ammonia.

3. Melting point (ºC): 21.2

4. Relative density (g /mL, 20/4ºC): 1.1242

5. Relative density (g/mL, 20/20ºC): 1.1258

6. Relative vapor density (g/ mL, air = 1): 5.14

7. Refractive index (20ºC): 1.482~1.485

8. Viscosity (mPa·s, 35ºC): 280

9. Viscosity (mPa·s, 100ºC): 15

10. Flash point (ºC, opening): 179

11. Evaporation Heat (KJ/mol, b.p.): 67.520

12. Heat of fusion (KJ/mol): 27.214

13. Critical temperature (ºC): 514.3

 14. Critical pressure (MPa): 2.45

 15. Vapor pressure (kPa, 20ºC): 0.0013

 16. Vapor pressure (kPa, 210ºC) :5.333

17. Vapor pressure (kPa, 252.7ºC): 8.707

18. Vapor pressure (kPa, 305.6ºC): 46.064

19. Solubility: soluble in water, methanol, acetone, chloroform, etc. Almost insoluble in non-polar solvents. Slightly soluble in ether and benzene
