| Abstract: | Adducts,Ca2/3(PW12O40)·9DMF·EtOH,Sr2/3(PW12O40)·8DMF·EtOH and Ba2/3(PW12O40)·9DMF were synthesized in non-aqueous solutions,Their compositions and Keggin structures were characterized by elemental analysis and IRspectrometry.The heats of addition reactions between calcium dodecatungstophosphate,strontium dodecatungstophosphate and barium dodecatungstophosphate with DMF and EtOH were respectively determined by solution calorimetry.The values were -207.4±2.3 kJ/mol,-197.1±5.4 kJ/mol and -270,9±2.4 kJ/mol at 30℃,respectively. |
