Results and discussion
Vapour pressure
- Key result
- Remarks on result:
- not determinable
- Remarks:
- At 118°C and 1.0 mmHg the material was observed to be solidified.
Any other information on results incl. tables
The vapor pressure could not be measured by the dynamic method since it did not show a stable reflux at any pressure and irreversibly solidified at 118 °C. Pressures were recorded at 80 °C and 118 °C but do not reliably show the substance vapor pressure since the vacuum controller was run continuous during the test.
Applicant's summary and conclusion
- Conclusions:
- The vapor pressure of MDP was not determinable (ASTM E-1719-97).
- Executive summary:
The vapor pressure of MDP was examined using dynamic method. The vapor pressure was not determinable due to thermal decomposition occurring at 118°C when the material was observed to be solidified. Also, no stable reflux was observed during the experiment. Because of self-reaction at elevated temperatures, this method is unsuitable for measuring vapor pressure of this substance. Therefore, the study is considered not reliable.
