Materials and methods

Test guidelineopen allclose all
Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Version / remarks:
27th July 1995
Deviations:
yes
Remarks:
Only one temperature: -25 °C
Qualifier:
according to
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Version / remarks:
18 march 2002
Deviations:
yes
Remarks:
Heating was omitted
Principles of method if other than guideline:
Deviations from guideline:
The sample is a fluid at +20°C, so heating can be omitted
From literature it can be assumed, that the freezing point is under -20°C.
For REACH the freezing point only has to be determined till a lower limit of -20°C,so: A pour point analysis is performed at only one temperature: -25 °C
The measure to avoid super cooling was adding a few anti bumping granules.
The deviations will not lead to a different conclusion, only simplify the method.
GLP compliance:
no
Type of method:
pour point

Results and discussion

Melting / freezing point
Melting / freezing pt.:
< -20 °C
Atm. press.:
101 325 Pa

Any other information on results incl. tables

After one week at below -25°C the surface of the substance moves, the substance is still fluid. A small rise in temperature may have occurred by removing the tubes from the freezer, but it is save to conclude the freezing point is below -20°C for this substance.

Applicant's summary and conclusion

Conclusions:
112-57-2,TEPA,
The freezing point of the substance is below -20°C.
