Executive summary:

In this publication from the Mellon Institute of Industrial Research, the physichal properties of ethylene dichloride, dichloroethyl ether, and isopropyl ether are compared to evaluate their value as industrial solvents. The vapour pressure of Bis(2-chloroethyl) ether was determined to be 0.73 mm Hg at 20°C. Due to a lack of methodological details, the reliability of this data cannot be assessed (reliability 4).

Description of key information

According to the Handbook of Environmental Data on Organic Chemicals (Verschueren, 1983), the vapour pressure of Bis(2-chloroethyl) ether is 1.867 hPa at 25°C.

Additional information

According to the Handbook of Environmental Data on Organic Chemicals (Verschueren, 1983), the vapour pressure of Bis(2-chloroethyl) ether is 0.947 hPa at 20°C and 1.867 hPa 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 (reliability score of 2).

In Doolittle (Ind. Eng. Chem., 1935, 27(10):1169 -79), the vapour pressure of Bis(2-chloroethyl) ether was determined to be 2 mm Hg (equivalent to 2.666 hPa) at 30°C based on a dynamic method. In Fife & Reid (Ind. Eng. Chem., 1930, 22(5):513-5), Bis(2-chloroethyl) ether was found to have a vapour pressure equal to 0.73 mm Hg (0.973 hPa) at 20°C. These data are very similar to the value selected as key information.
