Thermographic Data - Determination 1

Thermal Event Interpretation Temperature
°C K
Broad Endotherm Partial boiling with decomposition 175.2 448

Thermographic Data - Determination 2

Thermal Event Interpretation Temperature
°C K
Broad Endotherm Partial boiling with decomposition 176.57 450

Overall result: Partially boiled with decomposition from 176 +/- 1 °C (449 +/- 1K)

Conclusions:
The material was determined to partially boil with decomosition from 176 +/- 1 °C (449 +/- 1K) at 102.04 kPa.
Executive summary:

The boiling point of the test substance (PR-4758) was measured in accordance with international guidelines in a GLP testing laboratory, and the material was determined to partially boil with decomosition from 176 +/- 1 °C (449 +/- 1 K) at 102.04 kPa.

Description of key information

Boiling partially boil with decomposition from 176 +/- 1 °C (449 +/- 1 K) at 102.04 kPa; OECD 103; Butler & White (2010).

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
176 °C

Additional information

One key study exists where the boiling point of the test substance (PR-4758) was measured in accordance with international guidelines and in accordance with GLP. The material was determined to partially boil with decomposition from 176 +/- 1 °C (449 +/- 1 K) at 102.04 kPa.
