The dynamic viscosity at 20 °C was determined to be 2.22 mPas.
A literature search was conducted. The
available data were evaluated in a weight of evidence approach. All
relevant literature values were obtained in REAXYS database. Reaxys is a
database for the retrieval of chemistry information and data from
published literature including journals and patents. The information
includes chemical compounds, chemical reactions, chemical properties,
related bibliographic data, and substance data with synthesis planning
information, as well as experimental procedures from selected journals
and patents. Reaxys provide experimentally measured data covering
chemical reactions, physical, chemical or pharmacological properties.
The Reaxys database is regarded as reliable and was therefore taken into
account for this weight of evidence approach. Five independent
literature values were reported. Timmermans and Hennaut-Roland (1935)
report the dynamic viscosity to be 2.22 mPa.s at 20 °C. Furthermore
Yaw-Wen Sheu, Chein-Hsiun Tu (2006) report the dynamic viscosity to be
1.971 mPa.s at 25 °C, García et al (2004) report the dynamic viscosity
to be 1.973 mPa.s at 25 °C and Mumford and Phillips (1950) report the
dynamic viscosity to be 1.99 mPa.s at 25 °C. The dynamic viscosity is
temperature dependent and decrease with an increase of temperature. All
values reported at 25 °C were in the same range and support the dynamic
viscosity at 20 °C. Thus, the value at 20 °C was regarded as reliable
and was therefore chosen as key value for chemical safety assessment.
