VIS - Mixture Viscosities

Knowledge of the viscosity, especially in case of liquids is of great importance for selecting the right operating conditions in process synthesis. Numerous customers have inquired about experimental data and estimation methods in the past. DDBST therefore has started to build up a data bank for mixture viscosities and is proud to present the first version as part of DDB 2010.

In general, dynamic viscosities are about 10 times more frequent than kinematic viscosities. As in case of most data banks, there are some systems for which an especially large amount of data is available:

Cyclohexane Hexadecane
Benzene Cyclohexane
1,2-Ethanediol Water
Cyclohexane Tetradecane
Water 1,2-Propanediol
Methanol Water
1-Propanol Toluene
N,N-Dimethylformamide (DMF) 2-Methoxyethanol
Decane Methyl tert-butyl ether (MTBE)
Nonane Methyl tert-butyl ether (MTBE)
Methane Hydrogen
Hexane Squalane
Octane Squalane
n-Butane Squalane

The DDB online search system shows the current number of sets, points, and systems: Mixture Viscosity Overview.
