Executive summary:

Hexan-1-ol was determined according ASTM D 445. The viscosity was determined to be 3.64mm²/s at 40 °C.

Description of key information

The kinematic viscosity of hexan-1-ol is  3.64 cSt (3.64 mm2/s) at 40°C.

Key value for chemical safety assessment

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

Additional information

The kinematic viscosity of 3.64 mm2/s at 40°C was determined for hexan-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.
