Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

Endpoint:
particle size distribution (granulometry)
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is marketed or used in a non solid or granular form
Cross-reference
Reason / purpose for cross-reference:
data waiving: supporting information
Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
12 - 19 May 2005
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Deviations:
no
GLP compliance:
yes
Type of method:
method to determine freezing temperature
Specific details on test material used for the study:
SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: 41-2601-2240-7
- Expiration date of the lot/batch: 23 Mar 2006
- Purity: 99.959%
- Synonyms: MTDID 665
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL

Key result
Melting / freezing pt.:
-61 °C

Test was done at ambient atmospheric pressure (value not stated). Stable temperatures were observed around the freezing point. A clear phase transition was observed at temperatures of (-56.9) °C (test 1), (-61.2) °C (test 2), and (-61.0) °C (test 3). The average of two repeatable temperatures was reported as the freezing point.

Table, Measured temperatures around the freezing process.

 Temp during test 1 (°C)  Temp during test 2 (°C)  Temp during test 3 (°C)
 (-54.5)  (-61.0)  (-60.0)
 (-54.9)  (-60.9)  (-60.3)
 (-55.3)  (-61.1)  (-60.4)
 (-55.6)  (-61.0)  (-60.6)
 (-56.1)  (-61.2)  (-60.8)
   (-61.2)  (-60.9)
Conclusions:
The freezing point of HFE s-601 is (-61.0) °C (OECD 102)
Executive summary:

The freezing point range of HFE s-601 was determined by placing the test material in an acetone/dry ice bath with temperature probe readings. The study was conducted in accordance with the OECD 102 method and was GLP compliant; therefore the study is considered reliable without restrictions.
