Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Materials and methods

Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
Freezing and melting point determinations on a (2H)chloroform sample were run, and compared with (1H)chloroform.
The determinations were carried out in a double-jacketed container with air insulation. A copper-constantan thermopile of 2 couples enclosed in a flattened platinum tube was used with a glass container of similar shape which by the reduced volume allowed the entire thermopile to be covered with the liquid. The determinations were carried out under a pressure of 3 mm. to ensure removal of all gases which might have been formed.
GLP compliance:
no
Type of method:
method to determine freezing temperature

Any other information on results incl. tables

The observed values indicate that (2H)chloroform (melting point -64.69 - -64.15 °C) melts lower compared to (1H)chloroform (melting point = -63.77 - -63.33 °C), which is in accordance with the lower melting points of other organodeuterium compounds.
