Any other information on results incl. tables
In the temperature range of 50 – 140 °C, an endothermic effect with two peaks was observed, which was followed by a second endothermic effect in the temperature range of 130 – 160 °C. Both endothermic effects cannot be assigned to the melting of the test item. Two small exothermic effects were detected in the temperature ranges of 170 – 200 °C and 290 – 350 °C, with an overall decomposition energy of approx. -50 J/g. No further thermal effects were observed up to the test end temperature of 500 °C.
To verify the results of the DSC measurement, two additional measurements with the capillary method (Apparatus: Stuart Melting Point SMP30) were performed in the temperature range of 25 – 350 °C with a heating rate of 10 K/min. According to the observations during the test with the capillary method, the endothermic effects in the temperature range of 50 – 160°C in the DSC measurements cannot be assigned to the melting of the test item. Starting at a temperature of 50 °C the test item changed its crystalline structure and changed its colour from light yellow to dark yellow starting at a temperature of approx. 90 °C. A further change in colour from dark yellow to brown could be observed from a temperature of 220 °C. Between 250 – 270 °C the test item turns black. Due to this result, the test item has no melting and boiling point before its decomposition starting at a temperature of about 220 °C.
Applicant's summary and conclusion
- Conclusions:
- The test item 4-Nitrophenyl phosphate disodium salt (CAS no. 4264-83-9) has no boiling point up to its decomposition starting at a temperature of approx. 220 °C at atmospheric pressure (1016 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.2. and OECD Test Guideline 103 (1995).
- Executive summary:
The test item 4-Nitrophenyl phosphate disodium salt (CAS no. 4264-83-9) has no boiling point up to its decomposition starting at a temperature of approx. 220 °C at atmospheric pressure (1016 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.2. and OECD Test Guideline 103 (1995).
