- Melting and Boiling Point
No definitive signs of melting/boiling of the test item strontium bis 2-ethylhexanoate were observed by differential scanning calorimetry (DSC) measurements (open aluminium crucible under air and an open glass crucible under air, up to 600 °C, heating rate of 10 K/min) and by the capillary method (up to 400 °C, heating rate of 10 K/min). The measurements were performed according to Regulation (EC) No. 440/2008 Method A.1./A.2. and OECD Test Guideline 102/103 (1995) at atmospheric pressure (994 - 1006 hPa). It is assumed that the test item decomposes with a mass loss of >52 % at temperatures >300 °C.
Thermal Stability
In the temperature range of 190 °C to 240 °C the test item strontium bis 2-ethylhexanoate shows a very small exothermic effect with an energy of -20 J/g and an endothermic effect in the temperature range of 400 °C to 500 °C.
Reference
Melting and Boiling Point (DSC and Measurement in Test Glass)
The thermograms of the DSC runs PN14352 and PN14353 in an open aluminium crucible showed a broad endothermic effect in the temperature range of 380 °C to 550 °C. The thermogram of the DSC run PN15679 in an open glass crucible showed two small endothermic effects in the temperature range of 80 °C to 120 °C and of 150 °C to 270 °C, respectively. A third broad endothermic effect was observed in the temperature range of 350 °C to 580 °C.

It is not possible to assign any of the observed endothermic effects definitely to melting of the test item.
In view of the fact that the measured weight loss of each sample was only between 52 % and 56 % of the respective initial sample weight, none of the observed endothermic effects can be assigned to boiling of strontium bis 2-ethylhexanoate.
Measurements by the Capillary Method
For verification of the results the test item was additionally tested with the capillary method. The test item started to change the colour at ~300 °C from white to partly light yellow. At approx. 310 °C partly light brown, at ~340 °C partly grey/brown. The measurement was stopped at 400 °C with a brown/ grey/ black residue remaining in the capillary. Neither a melting nor a boiling of the test item could be observed. It is assumed, that the test item decomposes at temperatures >300 °C.
Thermal stability (DSC)
In the temperature range of 190 °C to 240 °C a very small exothermic effect was observed with an energy of -20 J/g. In the temperature range of 400 °C to 500 °C an endothermic effect was observed.
