The temperature of melting and melting enthalpy is presented in the
Table: Temperature of melting of Sr(OAC)2
No of measurement
310,25 ± 0,07
313,6 ± 0,56
46,25 ± 3,3
Remark: The values temperature obtained by DSC which is dynamic method
depends on heating rate and may be different from results obtained by
After dehydration of Sr(AC)2·0.5H2O at 180°C-212 °C (mass loss of
5,36%), the second step of mass loss 22,53% between 380 to 500 °C can be
assigned to the decomposition of anhydrous Sr(AC)2 to SrCO3. There are
two sharp endothermic peaks with maximum values of 313 and 340°C in DSC
curve with no corresponding mass loss in TG curve. It suggests two-phase
change processes occurred in this temperature range. The sharp DSC peak
at about 313°C can be assigned to the endothermic melting process.
The determination of the melting point was performed by Differential
scanning calorimetry with thermogravimetry as described in the OECD
Guideline 102 (Melting point/Melting Range).
After loss of water at 150°C, the melting started at 310°C. The sharp
DSC peak at about 313°C can be assigned to the endothermic melting
