- Executive summary:
The boiling temperature was determined using EU Method A.2 and OECD Method 103: Siwoloboff method under GLP. Decomposition was reported during the test. In the Siwoloboff method the test item was determined to decompose at 495 K (222°C) at 97.9 kPa, prior to boiling. Firstly bubbles emerge from capillary, unstable temperature at ca. 494K to 496K and/or a change of appearance of pale yellow liquid to brown liquid was observed at 504 to 508K. The decomposition was confirmed by Differential Scanning Calorimetry (DSC), the onset temperature was ca. 170°C and the exothermic peak was stated as 218.74°C. The integral was 307.37 mJ and energy release was stated as 16.53 J/g. Sample size 18.6 mg. Under the conditions of this study, the boiling temperature of the test item has been determined to be > 495 K (or > 222°C) at 97.9 kPa with decomposition confirmed by DSC at ca. 218°C.
Reference
Measured temperatures were converted from °C to K using T = t + 273
T = temperature (K)
t = temperature (°C)
