Probably because of a small amount of impurities, the melting process
started already at 75°C (348 K).
From the endothermic melting peak, the melting temperature of
Phytosphingosine was determined to be 101°C. The observed second small
endothermic peak between 143°C and approximately 150°C may be caused by
further melting (possibly some components or impurities with higher
melting temperatures). It is also possible that the test substance shows
liquid crystalline behaviour. In that case, the second peak may be
caused by the transition from the liquid crystalline state to the
isotropic liquid state. The observed exothermic effect was probably
caused by reaction or decomposition of the test substance.
The melting temperature of Phytosphingosine was determined to be 101°C
(374 K). Probably because of a small amount of impurities, the melting
process started already at 75°C (348 K).
Reaction or decomposition started at 148°C (421 K). Boiling of the test
substance was not observed below the temperature at which reaction or
