Type of information:

experimental study

Adequacy of study:

supporting study

Reliability:

4 (not assignable)

Rationale for reliability incl. deficiencies:

documentation insufficient for assessment

Principles of method if other than guideline:

- Principle of test: not specified
- Short description of test conditions: no data available

Specific details on test material used for the study:

TEST MATERIAL:
- Name (as cited): Dichloroethyl ether
- Purity: not specified

Melting / freezing pt.:

-51.7 °C

Conclusions:

The freezing point of Bis(2-chloroethyl) ether was determined to be -51.7°C.

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.
