Results

To determine the boiling behaviour (two independent single measurements), the test item was measured by DSC between 5 °C and 450 °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 Propyl oleate shows a boiling and/or thermal decomposition earliest at ca. 359 °C (at 1004 mbar) according to the definition in the OECD guideline 103.

360 °C (from first measurement)

359 °C (from second measurement)

From 359 °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.
