Key result

Boiling pt.:

> 673 K

Atm. press.:

100.02 kPa

Decomposition:

yes

Decomp. temp.:

476 K

Thermographic data - Determination 1

Thermal event	Interpretation	Temperature
		°C	K
Onset of exotherm (low energy)	Possible onset of decomposition	203.3	476

No endothermic behaviour occurred up to a temperature of 400 ± 0.5 °C (673 ± 0.5 K). The boiling temperature is therefore considered to be greater than 673 ± K.

Atmospheric pressure: 100.20 kPa

 

Thermographic data - Determination 2

Thermal event	Interpretation	Temperature
		°C	K
Onset of exotherm (low energy)	Possible onset of decomposition	203.3	476

No endothermic behaviour occurred up to a temperature of 400 ± 0.5 °C (673 ± 0.5 K). The boiling temperature is therefore considered to be greater than 673 ± K.

Atmospheric pressure: 100.20 kPa

Conclusions:

The boiling temperature of has been determined to be greater than 673 + 0.5 K at 100.02 kPa.
Low energy exothermic behaviour from approximately 476 K suggests that there is some chemical change (possible onset of decomposition) of the material during the determination.

Executive summary:

Greater than 673 + 0.5 K at 100.02 kPa, by differential scanning calorimetry, using ASTM E537-86 and Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.

Low energy exothermic behaviour from approximately 476 K suggests that there was some chemical change (possible onset of decomposition) of the material during the determinations.

 

From vapour pressure data (Safepharm Laboratories Project Number 4451285) and the chemical structure, the boiling temperature is estimated to be greater than 673 K at 101.325 kPa.
