- Remarks on result:
- other: Second boiling point, corrected for standard atmospheric pressure (6th assay)
- Conclusions:
- The test item, mainly composed of unsaponifiables, glycerides and free fatty acids, shows an endothermic temperature interval between 300 and 360 °C (complex boiling area most likely due to the complex composition), and a true boiling point at 408 °C.
Reference
Six assays were performed during the test. Two endothermic peaks were observed.
The corrected temperature values obtained varied between 318.8 and 319.3 °C for the first endothermic peak, and between 403.3 and 421.7 °C fo r the second endothermic peak.
The mean value for the boiling point is explained as the mean of at least two assays for which the boiling point value was in the range of the estimated accuracy of the method: ± 0.5 °C up to 326.9 °C and ± 2.0 °C above 326.9 °C
Four assays were not taken into account.
For the first boiling point (first and second assay), the endothermic area is more evocative of an endothermic temperature interval between 300 and 360 °C than of a real endothermic p eak, so the term “peak” and the theoretical value derived by the software do not seem to be applicable.
