Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Study period:
- 1996
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Read-across from an analogue substance for which a study conducted with a method equivalent to a guideline study (Klimisch 2) is available.
- Justification for type of information:
- REPORTING FORMAT FOR THE ANALOGUE APPROACH
See cross-reference to justification of read-across. - Reason / purpose for cross-reference:
- read-across source
- Reason / purpose for cross-reference:
- read-across: supporting information
- Key result
- Melting / freezing pt.:
- 199.18 K
- Remarks on result:
- other: Based on a read-across from an analogue substance.
- Remarks:
- Adiabatic calorimetry
- Key result
- Melting / freezing pt.:
- 199.5 K
- Remarks on result:
- other: Based on a read-across from an analogue substance.
- Remarks:
- Differential scanning calorimetry
- Conclusions:
- Based on the read-across from the analogue substance d-limonene, l-limonene is concluded to have a melting temperature of 199.5 ± 0.5 K (DSC) and 199.18 ± 0.05 K (adiabatic calorimetry).
- Executive summary:
A study was performed similarly to OECD Guideline 102 to determine the melting point of d-limonene using differential scanning calorimetry (DSC) and adiabatic calorimetry. Based on the read-across from the analogue substance d-limonene, l-limonene is concluded to have a melting temperature of 199.5 ± 0.5 K (DSC) and 199.18 ± 0.05 K (adiabatic calorimetry).

Description of key information
Key study: Read-across from analogue substance. Test method OECD 102. No data on GLP. Melting point of l-limonene is concluded to be -74 °C (199 K).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -74 °C
Additional information
The key value is read-across to the enantiomer d-limonene using DSC and adiabatic calorimetry with accurate results of melting point (199.5 K and 199.18 K) and is supported by similar values (-74°C) from secondary literature on d-limonene and l-limonene.
