Description of key information

The viscosity of 5-methylheptan-3-one  was calculated as 0.848 ± 0.004 mPa * s at 20.0 ± 0.2 °C which is the mean of two values. Precision of the value is given as standard deviation of determination.

Additional information

Using a falling ball viscosimeter, a viscosity of 0.848± 0.004 mPa * s was measured for 5 -Methylheptan-3 -one. This value is the mean of two independent determinations (each consisting of three experiments) with their standard deviation. Good correlation of the two determinations was given (relative standard deviation was 0.43%). All measurements were performed at 20.0 ± 0.04 °C.
