Date: 2009 -10 -05

Operator: J.Wolter

reference sample: Brookfield Standard Ser. No. A56933

dynamic viscosity (theory): 99.0 mPas

temperature: 25.0 °C

dynamic viscosity (experimental): 97.8 mPas

Measurement

(tripple determination)

density in g/ml: 0.8013 / 0.8013 / 0.8014

kinematic viscosity in mm²/s: 8.0 / 8.0 / 8.0

dynamic viscosity in mPas: 6.4 / 6.4 / 6.4

atmospheric pressure in mBar: 1013.3 / 1013.3 / 1013.3

Conclusions:
A dynamic viscosity value of 6.4 mPas at 80°C was determined for the substance using a relevant test method. The result is considered to be reliable.
Executive summary:

Eicosan-1 -ol was determined according ASTM D 7042. The viscosity was determined to be 6.4 mPas at 80°C.

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.
