Lorz PM, Towae FK, and Bhargava N (Ullmann's Encyclopedia of Industrial Chemistry, 2002)
Melting point of phthalimde: 238 °C
Referenceopen allclose all
Atmospheric pressure is not reported.
Atmospheric pressure was not reported.
Beilstein reports several melting point values from 52 original references. Reported values were between 189 and 238°C, highest values in the range of 225-238 °C were more abundant.
Atmospheric pressure is not reported.
Description of key information
Numerous references report consistent values in the range between 233-238°C, with the value of 238°C being the most frequently reported.
One source reports considerably lower values (156-157°C), which cannot be explained due to the lack of information on the method used. This data point is disregarded as aberrant.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 238 °C
