Abstract: | The dehydration process of Co(II), Cu(II)
and Zn(II) methanesulfonates was studied by thermogravimetry/derivative thermogravimetry
(TG/DTG) and differential scanning calorimetry (DSC) techniques in dynamic
N2 atmosphere. The TG/DTG curves show that all of them
contain four crystallization water molecules, which are lost in two steps.
The peak temperature and dehydration enthalpies ΔH
were measured from DSC curves for each compound. The effect of procedural
variables on the TG and DSC curves was investigated. In this work, the procedural
variables included heating rate, Al pan state (unsealed and sealed) and sample
mass. |
