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
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Test procedure in accordance with national standard methods (OECD) without GLP.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- GLP compliance:
- no
- Type of method:
- method to determine freezing temperature
- Specific details on test material used for the study:
- - Name of test material (as cited in study report): Alcohols, C2-33, manuf. of, by-products from overheads
- Substance type: Product, HF-1000
- Physical state: clear colourless liquid
- Odour: oily/solvent
- Lot/batch No.: 1881046 - Melting / freezing pt.:
- < -20 °C
- Atm. press.:
- 1 atm
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- The test substance clearly freezes below -20 °C by visual assessment and this is supported by the thermal event in the DSC cooling trace at -58.8 °C. There is a temperature releated event at between 4 °C and -20 °C that again is supported by the thermal cooling trace at approximateley -18 °C that indicates some sort of transition or crystallisation is occuring. As the test substance is a UVCB, this could be due to some components in the test substance starting the freezing process.
- Executive summary:
Hydrocarbons, C12-C16, n-alkanes, isoalkanes, alkenes is measured according to OECD 102.
The freezing point was determind to be below -20 °C.
Reference
Equipment:
Type: TA Instruments Q1000 DSC
Calibration:
calibration material: Indium and cyclohexane
melting point (theory): Indium: 157.01 °C; cyclohexane: 6.45 °C
melting point (experimental): indium: 156.55 °C; 6.53 °C
Substance analysis:
The test substance, Alcohols, C2-33, manuf. of, by-products from overheads was analysed by heating in a sealed pan from -80 °C to 25 °C at the heating rate of 10 °C/min. This was then held isothermally for 10 mins at 25 °C and then cooled down to -80 °C at a heating rate of 10 °C/min. A nitrogen purge gas was used.
Results:
The heating trace shows a thermal transition occuring between -12.8 °C and -14.72 °C. No melt was observed.
The cooling trace shows a thermal transition occuring between -18.22 °C and -18.93 °C, which could be a differential cooling of some of the test substance components. A second thermal transition appears at -58.8 °C.
