Reference
1 Boiling Point (DSC)
Results of DSC-measurements:
Four endothermic effects were detected in the temperature ranges of 40 – 60 °C, 60 – 140 °C, 150 – 220 °C and 310 – 450 °C.
Table 1: Results of the DSC measurements
Measurement No. | Sample weight / mg | Onset of Effect / °C | Range of effect / °C | Weight loss / mg |
1 | 9.86 | 52.69 | 40 – 60 (endo) | 9.85 |
2 | 9.61 | 52.46 | 40 – 60 (endo) | 9.61 |
Four endothermic effects were detected in the temperature ranges of 40 – 60 °C, 60 – 140 °C, 150 – 220 °C and 310 – 450 °C.
2 Boiling Point (Photo Cell Detection Method)
The first measurement was carried out with visual observations. The second and third measurements were done automatically. As soon as the frequency of 0.6 Hz was reached, this temperature was evaluated as the boiling point.
Table 2: Results of the additional tests
No. | Filling height / mm | Temperature range / °C | Heating rate / K/min | Observations |
1 | 7 | 60 – 90 | 10 | 60 °C: clear, colourless liquid |
2 | 7 | 120.8 | 10 | 120.8 °C: Frequency of 0.6 Hz exceeded |
3 | 9 | 119.3 | 1 | 119.3 °C: Frequency of 0.6 Hz exceeded |
3 Assessment of both methods
During the heating phase in the DSC measurement a distinct endothermic effect was observed in the temperature range of 40 – 60 °C, which can be assigned to the melting of the test item.
During the further heating phase in the DSC measurement the test item showed a second endothermic signal in the temperature range of 60 – 140 °C. The photo cell detection method visually confirmed boiling at these temperatures (90 – 150 °C).
Thus, the capillary method was performed. In two capillaries with a heating ramp of 10 K/min, boiling points of 111.0 and 120.8 °C were detected automatically by the apparatus. With correction for the air pressure (1009 and 990 mbar, respectively), the boiling range in the capillary method was 111.2 to 121.6 °C. In one capillary with a heating ramp of 1 K/min, a boiling point of 119.3 °C was detected automatically by the apparatus. With correction for the air pressure (1020 mbar), the boiling point in the capillary method was 119.1 °C.
Due to the fact that the BÜCHI Apparatus detected the boiling temperature clearly, this temperature is used as boiling range of the test item. The boiling range determined in the capillary method was 111.2 to 121.6 °C
A third endothermic signal is observed in the DSC measurement in the temperature range of 140 – 220 °C. The photo cell detection method visually confirmed boiling at these temperature range (150 – 260 °C) with decreasing frequency. At the end of the measurement with a heating ramp of 1 K/min at 190 °C the test item began to change colour from colourless to yellow. This suggests that a decomposition reaction is starting.
The fourth endothermic signal which is observed in the DSC measurement in the temperature range from 310 – 450 °C could not be clearly assigned to the boiling of the test item. Perhaps it is further decomposition of the test item.
No further thermal effects were observed up to the test end temperature of 500 °C.
4 Final Results
The test item NDPSa has a boiling range from 111 °C to 121 °C at atmospheric pressure (1013 hPa) as determined by differential scanning calorimetry and by the photo cell detection method according to Regulation EC No. 440/2008 Method A.2. and OECD Test Guideline 103 (1995).
