Description of key information
The kinematic viscosity of nonan-1-ol is 12.97 mm2/s at 20°C.
Key value for chemical safety assessment
- Viscosity:
- 12.97 mm²/s (static)
- at the temperature of:
- 20 °C
Additional information
The kinematic viscosity of 12.97 mm2/s was determined for nonan-1 -ol with the use of a capillary method in accordance with ASTM D446/07. The result is considered to be reliable. A value of 9.23 mm2/s at 40°C was determined in the same test.
Discussion of trends in the Category of C6-24 linear and essentially-linear aliphatic alcohols:
As chain length increases, kinematic viscosity increases. This is because molecular weight is higher and intermolecular forces in the substance are all higher.
