- Remarks:
- no atm. pressure mentioned in the report, but 1013 hPa as standard conditions can be assumed
Any other information on results incl. tables
Endotherm #1: 110.7 °C – 123.93 °C
Breaking of complex between residual THF and LiBH4
Endotherm #2: 258.6 °C – 293.0 °C
Literature melting point for LiBH4 = 275 °C. Literature melting point is the mid-point for this melting range.
Applicant's summary and conclusion
- Conclusions:
- The melting point of the substance is 275 °C.
- Executive summary:
The melting point of the test item was tested via DCS measurement. An endothermal effect (breaking of complex between residual THF and LiBH4) was observed in the temperature range of 110.7 °C – 123.93 °C . A second endothermal effect (melting) was observed in the temperature range of 258.6 °C – 293.0 °C. The test item has a melting point of 275 °C.
No atm. pressure is mentioned in the report, but 1013 hPa as standard conditions can be assumed.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
