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:
- 2009-11-25
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Remarks:
- Detailed description of measurement was stated; purity, expiration date and storage conditions of the test item are missing.
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- 1995
- Deviations:
- no
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- 2008
- Deviations:
- no
- Principles of method if other than guideline:
- The measurement was performed by the house method of Schill und Seilacher "STRUKTOL" AG. The test item was pulverized and put into three capillary tubes and heated up with a heating rate of 1K/min from 90 °C on. The test item was irradiated by a light source. The light which has gone through the test item (transmission) was measured by a detector. When the test item melted the signal at the detector raised. The raising of the transmission of 20 % is defined as the melting point.
- GLP compliance:
- no
- Type of method:
- capillary method
- Melting / freezing pt.:
- 101.1 °C
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: st.dev. = 1.48 °C
- Conclusions:
- Fatty acids, C14-18 and C16-18-unsatd., zinc salts starts melting at 101.1 °C with a standard deviation of 1.48 °C.
