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:
- 21/03/2016 - 21/03/2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Justification for type of information:
- Data is from experimental study report
- Qualifier:
- according to guideline
- Guideline:
- other: as entioned below
- Principles of method if other than guideline:
- The freezing point of a pure sample is determined by making measurements of the temperature as a function of time while the sample is submerged in a constant temperature bath at a temperature below that of the expected freezing point of the sample. The data (Temperature vs. time) is plotted; this plot is known as a cooling curve. The freezing point is the value of temperature in the flat portion of the curve.
- GLP compliance:
- no
- Type of method:
- other: Method according to Cooling Curve
- Key result
- Melting / freezing pt.:
- -16 °C
- Atm. press.:
- 974.1 hPa
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: No other details available
- Conclusions:
- The Freezing point of test substance was determined with crushed ice and salt cooling bath and the mean freezing point was found to be -16.8 °C at 974.1 hPa.
- Executive summary:
The Freezing point determination of test substance was done using crushed ice and salt cooling bath. The determination was done on the basis of cooling curve (time vs temperature) obtained when the test item was placed in the cooling bath. The mean freezing point was determined to be -16.8 °C at 974.1 hPa.
