- 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 freezing point of Bis(2-chloroethyl) ether was determined to be -51.7°C. Due to a lack of methodological details, the reliability of this data cannot be assessed (reliability 4).

Description of key information
In the CRC handbook, Bis(2-chloroethyl) ether is described as having a freezing point of -51.9°C. The data originate from a recognised handbook and is thus considered as reliable.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -51.9 °C
Additional information
Three freezing point values are available in the literature. In the CRC handbook, Bis(2-chloroethyl) ether is described as having a freezing point of -51.9°C. As the data originate from a recognised handbook it has been assigned a reliability score of 2. A similar value is included in the Handbook of Environmental Data on Organic Chemicals (Verschueren, 1983), where it is stated that the freezing point of Bis(2-chloroethyl) ether is -50°C (reliability 2). Finally, in an experimental study by Fife & Reid (Ind. Eng. Chem., 1930, 22(5):513-5), an experimental value of -51.7°C is reported. However, the methodology used to measure the freezing point of the substance is not described and this data has been assigned a reliability score of 4.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
