| Abstract: | LaAc3·1.5H2O(Ⅰ)and LaAc3·5H2O (Ⅱ) have been prepared ,by new synthesis methods and characterized by elemental analysis, thermogravimetry and vacuum dehydration over P2O5. Their dehydration processes and enthalpy changes have been also determined by means of DTA-TG-DTG and DSC techniques respectively. |
