Viscosity of N,N-Dimethylbenzylamin was determined to be 0.02643 Pa·s at 20 °C and 0.00343 Pa·s at 40 °C.

Executive summary:

The viscosity of the test item was determined according to DIN 53019 guideline, rotational viscometer method.


N,N-dimethyl-1-phenylmethanamine has a viscosity of 0.02643 Pa·s at 20 °C and 0.00343 Pa·s at 40 °C.

Description of key information

N,N-Dimethylbenzylamin has an experimentally measured viscosity of 26.43 mPa·s at 20 °C and 3.43 Pa·s at 40 °C (DIN 53019; Bayer, 2011).



Can be regarded as a fluid liquid (based on CLP criteria for aspiration hazard < 20,5 mm2/s at 40°C).


Key value for chemical safety assessment

Viscosity:
26.43 mPa · s (dynamic)
at the temperature of:
20 °C

Additional information

A reliable, guideline, experimental study is available, and therefore considered as key.


Assuming a density of 0,9, as presented under IUCLID section 4.4, dynamic viscosity can be converted to kinematic viscosity, respectively 29.4 mm2/s at 20°C and 3,8 mm2/s at 40°C.
