Parameter:

dynamic viscosity (in mPa s)

Value:

Conclusions:

The viscosity of Bis(2-chloroethyl) ether was determined to be 2.41 mPa.s at 20°C and 2.14 mPa.s at 25°C.

Executive summary:

In a peer-reviewed publication by Mumford & Philips, the viscosity of Bis(2-chloroethyl) ether was determined in small Ostwald-type viscometers conforming in general characteristics to the standards laid down in British Standard Specifications N°188-1929. The viscosity was measured at two temperature (20 and 25°C). The means of at least two determinations, performed with different bottles, was recorded at each temperature. The viscosity of Bis(2-chloroethyl) ether was found to be 2.41 mPa.s at 20°C and 2.14 mPa.s at 25°C.

The publication includes sufficient methodological details and has been subject to peer-review. Accordingly, it has been assigned a reliability score of 2.

Conclusions:

The dynamic viscosity of Bis(2-chloroethyl) ether is 2.41 mPa.s at 20°C and 2.065 mPa.s at 25°C.

Executive summary:

In this data book, it is stated that the dynamic viscosity of Bis(2-chloroethyl) ether is 2.41 mPa.s at 20°C and 2.065 mPa.s at 25°C.

Handbook data are considered reliable as it is assumed that a variety of data sources have been consulted, that the test methodology and identity of the test substance has been evaluated, and that a reliable and representative value for the endpoint has been selected. Accordingly, this data has been assigned a reliability score of 2.

Description of key information

Additional information

In a peer-reviewed publication by Mumford & Philips (J. Chem. Soc., 1950, 75-84), the viscosity of Bis(2-chloroethyl) ether was determined in small Ostwald-type viscometers conforming in general characteristics to the standards laid down in British Standard Specifications N°188-1929. The viscosity was measured at two temperature (20 and 25°C). The means of at least two determinations, performed with different bottles, was recorded at each temperature. The viscosity of Bis(2-chloroethyl) ether was found to be 2.41 mPa.s at 20°C and 2.14 mPa.s at 25°C.

In Lange's Handbok of Chemistry (15th Ed.), it is stated that the dynamic viscosity of Bis(2-chloroethyl) ether is 2.41 mPa.s at 20°C and 2.065 mPa.s at 25°C. Handbook data are considered reliable as it is assumed that a variety of data sources have been consulted, that the test methodology and identity of the test substance has been evaluated, and that a reliable and representative value for the endpoint has been selected. Accordingly, this data has been assigned a reliability score of 2. However, priority was given to data originating from original publication for key value selection.
