Results

To determine the boiling behaviour (three independent single measurements), the test item was measured by DSC between 5 °C and 400 °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 shows a boiling and/or thermal decomposition earliest at ca. 203 °C (at 1004 mbar) according to the definition in the OECD guideline 103.

203 °C (from first measurement)

204 °C (from second measurement)

203 °C (from third measurement)

From 203 °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.

Conclusions:

The test item shows a boiling and/or thermal decomposition earliest at ca. 203 °C (at 1004 mbar) according to the definition in the OECD guideline 103.

Executive summary:

The boiling temperature of the test item was determined in accordance with the test method OECD Guideline Test 103 “OECD Guideline For The Testing Of Chemicals, adopted by the Council on 27th July 1995, Boiling Point” (similar to the test method A.2. "Boiling temperature" as described in the Official Journal of the European Communities L383A). The test item shows a boiling and/or thermal decomposition earliest at ca. 203 °C (at 1004 mbar) according to the definition in the OECD guideline 103.

Description of key information

The test item shows a boiling and/or thermal decomposition earliest at ca. 203 °C (at 1004 mbar) according to the definition in the OECD guideline 103.
