Description of key information

The kinematic viscosity of tetradecan-1-ol is 2.845 mm²/s at 100°C.

Key value for chemical safety assessment

Viscosity:
2.845 mm²/s (static)
at the temperature of:
100 °C

Additional information

A kinematic viscosity value of 2.845 mm²/s at 100°C was determined for tetradecan-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.
