Key value for chemical safety assessment

Viscosity:
11.251 mm²/s (static)
at the temperature of:
40 °C

Additional information

The kinematic viscosity of 11.251 mm2/s at 100°C was determined for dodecan-1-ol with the use of a capillary method in accordance with ASTM D445. The result is considered to be reliable.

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.
