Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- October 1994
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Principles of method if other than guideline:
- Differential scanning calorimetry or DSC is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. Both the sample and reference are maintained at nearly the same temperature throughout the experiment.
- GLP compliance:
- not specified
- Type of method:
- other: differential scanning calometry
- Key result
- Melting / freezing pt.:
- 74 °C
- Atm. press.:
- ca. 1 013 hPa
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- The melting point of 3,4-Dichlorobenzonitrile is 74 °C.
- Executive summary:
The melting point of 3,4 -Dichlorobenzonitrile was determined applying differential scanning calorimetry. The test protocol is equivalent to the guideline EU A.01. The test substance was put into a platen at room temperature and heated up. The peak of the endothermic heat fluxes were reported and the melting point of 3,4 -Dichlorobenzonitrile is 74°C.
Reference
The melting point of 3,4 -Dichlorobenzonitrile was determined applying DSC. The melting point is reported as the peak of the endothermic heat fluxes at 74 °C.
Description of key information
