- Melting and Boiling Point
The test item copper naphthenate has a melting range in the temperature range of -37 °C to -31 °C at atmospheric pressure (1002 - 1017 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.1. and OECD Test Guideline 102 (1995) and confirmed by visual observation in a test tube.
No definitive signs of boiling of the test item copper naphthenate were observed by differential scanning calorimetry (DSC) and by the capillary method up to the decomposition, beginning at 230 °C. The measurements were performed according to Regulation (EC) No. 440/2008 Method A.2. and OECD Test Guideline 103 (1995) at atmospheric pressure (1004 – 1017 hPa).
Thermal Stability
The test item copper naphthenate showed an endothermic effect in the temperature range of 190 – 230 °C and an exothermic effect in the temperature range of 330 °C to 430 °C with an average energy of -70 J/g.

During the cooling phase, no thermal effects were observed, which can be assigned to the freezing of the test item.
During the heating phase a very small endothermic effect was observed in the temperature range of -40 to -10 °C, which can be assigned to the melting of the test item.
The test item showed an endothermic signal in the temperature range of 190 °C to 260 °C and in the temperature range of 250 °C to 310 °C, directly followed by an exothermic effect in the temperature range of 290 °C – 600 °C with an energy* of -340 J/g and -580 J/g, respectively. In view of the fact that the measured weight loss of each sample was only between 63 % and 67 % of the respective initial sample weight, none of the observed endothermic effects can be assigned to boiling of copper naphthenate.
*Negative energy for exothermic processes, positive energy for endothermic processes
Measurements by the Test Tube
Due to the untypical very small melting peaks in the DSC, the melting of the test item was verified in the following the test tube. For this purpose approx. 3.2 g of the test item in a test tube were cooled down with liquid nitrogen to approx. -60 °C. In the temperature range of approx. -60 to -37 °C the test item was solid. The appearance of the test item during warming up at approx. -30 °C was very viscous green pasty and at -10 °C viscous green pasty. Due to this result the melting point in the DSC-measurement was confirmed.
Measurements by the capillary method
For verification of the results the test item was additionally tested with the capillary method. At 226 °C gas formation was observed. The measurement was stopped at 230 °C with a brown to orange residue remaining in the capillary. Therefore, the test item decomposes at approx. 230 °C.
Thermal Stability (DSC)
The DSC runs PN15672 and PN15714 showed in the temperature range of 190 °C to 225 °C a small endothermic effect and in the temperature range of 330 °C to 430 °C an exothermic effect was observed with an energy of -60 J/g and -70 J/g, respectively. The course of the temperature signal from above 420 °C and 430 °C, respectively can be assigned to a pressure rise inside the crucible, due to evaporating test item or gas decomposition products.
