- Conclusions:
- In the test condition boiling point of DOP (=DEHP) is 374.15°c at atmospheric pressure (1022 mbar)
- Executive summary:
According to the ASTM E1782 standard, boiling point of dioctylphthalte (= DEHP) has been measured in a dynamic method under low pressure.
The relationship between temperature and pressure is the following :
ln P (mbar) = [- 13848 / T (°K)] + 28.348
This relationship is linear.
In the test condition boiling point of DEHP at atmospheric pressure (1022 mbar) is 374.15°C
As the study follows an international standard, this study is considered as reliable without restriction.
Reference
The low pressures tested give different boiling point for DOP. The relationship between these data give a linear regression (see figure 1) that follows the equation:
ln P (mbar) = [- 13848 / T (°K)] + 28.348Description of key information
Boiling point: 374.15°C at 1022 mbar (ASTM E1782 standard: dynamic method under low pressure)
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 647 K
Additional information
Five data are available for boiling point of DEHP.
The key study, CCRA, 2008, is an experimental study according to ASTM E1782 standard.
All other data are cited from reference handbooks and are consistent with the value of the key study. Therefore these data are considered as supportive studies.
- Rippen, 2000: 385 °C at 1013 hPa
- Verschueren, 384 at 1013 hPa
- Patty, 1994: 230°C at ca 664 Pa (5 mmHg)
- BUA, 1986: 230-233°C °C at 5 mbar , DIN 53 406, not distillable at 1030 mbar.
