研究了SiMo12和PMo12杂多酸(HPA)的空气和真空脱水，通过在不同条件下检测到的Mo5+信号序列，可以评估HPA脱水和破坏的不同阶段。当HPA被支承在Aerosil上时，其稳定性会下降。HPA与氧化铝载体的强相互作用影响和改变了HPA的性质特征。
Air and vacuum dehydrations of SiMo12 and PMo12 heteropoly acids (HPA) have been studied, the sequence of Mo5+ signals detected under various conditions allowing the evaluation of different stages in the dehydration and destruction of the HPA. The stability of the HPA is shown to decrease when they are supported on Aerosil. The strong interaction of the HPA with an alumina support both influences and modifies properties characteristic of the HPA.
