July 9, 2008 - September 16, 2008
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Deviations:
yes
Remarks:
The main test was not performed in duplicate, but a preliminary test was performed
Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Qualifier:
according to
Guideline:
other: ISO 1392 Determination of crystallizing point, 1977
Principles of method if other than guideline:
The freezing point was determined by cooling the test item in sample tubes following study guidelines. The temeperature during crystallization was observed.
The freezing temperature of the test item is defined as the temperature at which phase transition from liquid to solid state take place at normal atmospheric pressure
GLP compliance:
yes (incl. certificate)
Type of method:
method to determine freezing temperature

CoA: Dr. Straetmans Chemische Produkte GmbH, June 16, 2008
Colourless liquid
Key result
Melting / freezing pt.:
ca. -8 °C
Atm. press.:
ca. 1 atm

The temperature of the test item decreased continuously. Starting from 20 °C, the test item was cooled to -40 °C.

The freezing temperature of the test item was determined at -8 °C. At the end of the experiment the test item was solid.

Conclusions:
The freezing temperature of the test item was determined at -8 ° C.
Executive summary:

The freezing point was determined by cooling the test item in sample tubes following study guidelines (EU method A.1, OECD 102, ISO 1392).

The temperature of the test item decreased continuously. Starting from 20 ° C, the test item was cooled to -40 ° C. The freezing temperature of the test item was determined at -8 °C. At the end of the experiment, the test item was solid.

Description of key information

The freezing temperature of the test item was determined at -8 ° C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
