1997-05-11 to 1997-12-29
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
Qualifier:
according to
Guideline:
EU Method A.2 (Boiling Temperature)
Version / remarks:
Directive 92/69/EEC, A.2.
Deviations:
no
GLP compliance:
yes
Type of method:
differential scanning calorimetry
Boiling pt.:
ca. 190 - ca. 209 °C
Atm. press.:
1 atm
Decomposition:
yes
Decomp. temp.:
210.3 °C

The boiling range of the test item was 190 to 209 °C (463 to 482 K). This relatively long endothermal 

proceeding (boiling range) rapidly passed over into a short exothermal heat flow (decomposition) at 210.3 °C (483.5 K).

Conclusions:
A boiling range of 190-209 °C was determined in an experimental study according to EU method A.1, and in compliance with GLP.
Executive summary:

A boiling range of 190-209 °C was determined in an experimental study according to EU method A.1, and in compliance with GLP. The study showed that the test item decomposes at 210.3 °C.

Description of key information

The boiling range of the test item is 190 -209 °C.

Key value for chemical safety assessment

Additional information

The boiling range of the test item was found at ca. 190 to 209 °C (463 to 482 K) using differential scanning calorimetry (Schneider 1997).

This relatively long endothermal proceeding (boiling range) rapidly passed over into a short exothermal heat flow (decomposition) at 210.3 °C (483.5 K).
