Results and discussion
Boiling point
- Atm. press.:
- 101.32 kPa
- Decomposition:
- yes
- Decomp. temp.:
- 483 K
- Remarks on result:
- other: As the test material decomposed, no value for boiling temperature could be determined.
Any other information on results incl. tables
Similar thermographic profiles were obtained using air and nitrogen atmospheres; this indicates that the observed decomposition in both determinations is probably thermal and not oxidative.
The large endotherm at 368 and 364 K in the two thermograms was considered to be the water component of the test material. The endotherm is broad because the water evaporates as the crucible heats up. Usually, a crucible is sealed with a lid that has a very tiny hole that helps create pressure within the crucible and significantly reduces the loss of material before its boiling temperature. As the test material contained a significant amount of phosphoric acid, it was considered that this could react with an aluminium crucible so platinum crucibles were used. The platinum crucibles were not sealed and have a much larger hole in the lid, preventing the pressure build up, and hence sharper boiling endotherms.
A visual appraisal was carried out using a heated metal block apparatus. This demonstrated that the test material decomposed from approximately 465 K by way of the test material colour becoming darker. The colour continued to become darker, until at 503 K the test material had turned to a brown/black colour.
Applicant's summary and conclusion
- Conclusions:
- The test material was determined to decompose from approximately 483 ± 0.5 deg. K at 101.32 kPa. As the test material decomposed, no value for boiling temperature could be determined.
- Executive summary:
A study was conducted to determine the boiling point of synthetic inositol phosphates using differential scanning calorimetry (DSC), according to the procedure specified in ASTM E537-86, EU Method A2 Boiling Temperature.
The test material decomposed from approximately 483 ± 0.5 deg. K at 101.32 kPa. Therefore, no value for boiling temperature could be determined.
