Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- ca. 107.2 °C
- Atm. press.:
- ca. 1 010 hPa
Any other information on results incl. tables
The melting point / range was determined using a using a melting point system (MP80, Mettler
Toledo) according DIN EN ISO 3143 (previous version: DIN 53736). Two runs were done. The
onset-temperature is 118 °C. The clear point was reached at 121 °C.
The thermic behaviour of Phytosphingosine SLC was tested with a boiling point capillary from
room temperature up to 300 °C with a heating rate of 10 °C/min.
Arising bubbles were observed above a temperature of 124°C. Starting at 155 °C, the specimen
became more and more colorized. Finally, after cooling, the content of the tube appeared colored
and brownish.
Applicant's summary and conclusion
- Conclusions:
- The melting point of Phytosphingosine SLC was determined by differential scanning calorimetry: Melting Point: 107.2 °C ± 0.6 °C (1010 hPa).
- Executive summary:
The melting point of Phytosphingosine SLC determined by differential scanning calorimetry (OECD guideline 102, adopted 27th July 1995 and EU method A.1, 30 May 2008) is reported to be 107.2 °C ± 0.6 °C (1010 hPa).
