Key result

Atm. press.:

1 008 mBar

Decomposition:

yes

Decomp. temp.:

ca. 353 °C

Remarks on result:

not determinable

To determine the boiling behaviour (three in dependent single measurements), the test item was measured by DSC between 5°C and 500°C with a heating rate of 10 K/min. For the measurement a partially capsulated crucible, typical for boiling point measurements,was used.

 

The test item No.: 5424/18 shows a boiling and/or thermal decomposition earliest at approx. 353°C (at 1008 mbar) according to the definition in the OECD guideline 103.

 

353°C (from first measurement)

353°C (from second measurement)

354°C (from third measurement)

From 353°C the test item shows a boiling and/or thermal decomposition with evaporation of the decomposition components.

The DSC measurements were confirmed by means of TGA measurements under the same measuring conditions.

 

The start of the area of boiling temperatures is defined by using the on-set temperature.

 

Description of key information
