Key result
Boiling pt.:
>= 180
Atm. press.:
>= 101.1 - <= 101.7 kPa
Decomposition:
yes
Decomp. temp.:
>= 230 °C

The test item partially boiled from approximately 180 °C to 230 °C and then boiled with decomposition from approximately 230 °C.

As a result of the low rate of enthalpy change during thermal events, the onset temperatures could only be approximated. Non-similar residues were obtained using air and nitrogen atmospheres, using the same thermal programme; this indicates that the test item decomposed both thermally and oxidatively.

Conclusions:
The test item has been determined to partially boil from approximately 180 to 230 °C and then boil with decomposition from approximately 230 °C at 101.1 to 101.7 kPa.
Executive summary:

The test item was determined to partially boil from approximately 180 to 230 °C and then boil with decomposition from approximately 230 °C at 101.1 to 101.7 kPa, by differential scanning calorimetry, designed to be compatible with Method A.2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. As the test item decomposed, no value for boiling point of the whole test item could be determined.
