- Melting and Boiling Point
No definitive signs of melting of the test item manganese neodecanoate were observed by differential scanning calorimetry (DSC) measurements (open aluminium crucible under air, from -90 °C up to 500 °C and 600 °C, heating rate of 10 K/min). The measurements were performed according to Regulation (EC) No. 440/2008 Method A.1. and OECD Test Guideline 102 (1995) at atmospheric pressure (1004 – 1012 hPa).
In a test tube the test item shows a softening in the temperature range of approx. -20 °C to -17 °C at atmospheric pressure (1009 hPa).
No definitive signs of boiling of the test item manganese neodecanoate were observed by differential scanning calorimetry (DSC) measurements (open aluminium 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.2. and OECD Test Guideline 103 (1995) at atmospheric pressure (1004 – 1012 hPa). It is assumed that the test item decomposes at temperatures of >150 °C.
Thermal Stability
In DSC measurements (closed glass crucible under air, from room temperature up to 600 °C, heating rate of 3 K/min) according to OECD Test Guideline 113 (1981) the test item manganese neodecanoate showed no exothermic effects until the maximum test temperature of 600 °C, only a pressure rise starting at approx. 400 °C was observed.
Reference
Melting and Boiling Point (DSC)
In the temperature range of approx. -40 °C to -20 °C a very small endothermic effect was detected but it could not to be evaluated. Three endothermic effects was detected in the temperature ranges of 140 °C – 190 °C, 270 °C – 410 °C and 380 °C – 510 °C.

During the cooling phase, no thermal effects were observed, which can be assigned to the freezing of the test item.
During the heating phase the test item showed three endothermic signals in the temperature range of 140 °C – 190 °C, 270 °C – 410 °C and 380 °C – 510 °C which cannot definitely assigned to the boiling of the test item.
Measurements by the Test Tube
Due to the fact that a very small peak at approx. -30 °C in the DSC was observed, the melting of the test item was verified in a test tube. In the temperature range of -35 to approx. -20 °C the test item was solid. The appearance of the test item during warming up was at approx. -17 °C very pasty and remained pasty at 10 °C. The test item shows a softening in the temperature range of approx. -20 °C to -17 °C.
Measurements by the Capillary Method
For verification of the results the test item was additionally tested with the capillary method. At the start temperature, 30 °C, the test item showed dark brown and pasty-like. At approx. 80 °C the test item get liquescent. At approx. 150 °C the test item expanded and rised in the capillary. In the temperature range of 158 °C – 178 °C separate bubbles were observed. At 180 °C no bubbles could be observed anymore, the test item was partly solidified. At approx. 230 °C no liquid test item was observed anymore. The test item started to change the colour at ~240 °C from dark brown to light brown, at approx. 320 °C to 340 °C again to dark brown. At approx. 350 °C the test item was liquid and black. At 360 °C slow bubbles started, at 370 °C the test item was grey and turbid and from 385 °C to 400 °C a grey/ brown/ turbid, (like a suspension), residue suspension remained in the capillary.
No boiling of the test item could be observed. It is assumed, that the test item decomposes at temperatures of >150 °C.
Thermal Stability (DSC)
The test item manganese neodecanoate showed an endothermic effect in the temperature range of 330 °C - 410 °C. No exothermic effect was observed until the maximum test temperature of 600 °C. A pressure rise at approx. 400 °C was observed.
