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:
- May 30, 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- -70 °C
- Conclusions:
- The onset of melting for 2-ethylhexanoic acid, compound with 2-aminoethanol (1:1) was determined to be -70 °C. The complete melting of the substance, termed peak temperature, occurred at -62 °C.
- Executive summary:
An experiment was performed according to OECD Guideline 102 (Melting point / Melting Range) using the differential scanning calorimetry (DSC) method to determine the melting point of 2-ethylhexanoic acid, compound with 2-aminoethanol (1:1). An onset temperature and peak temperature of -70 and -62 °C, respectively, was determined for the registered substance. Onset of melting was regarded as the key value to satisfy the endpoint for melting point.
