杂多酸(盐)具有多种催化功能,广泛探讨杂多酸(盐)的性质、结构及其在反应中的变化,对了解杂多酸(盐)的催化作用是有意义的。研究固态杂多酸(盐)结构的热稳定性并予以评价,是当前杂多酸(盐)研究领域内引人关注的问题之一。这里涉及杂多酸的二次结构及杂多酸阴离子结构二个问题。前人由于局限于某一化合物和单一方法的研究,缺乏对杂多酸热 Heteropoly acid (salt) has a variety of catalytic functions, extensively explore the nature of heteropoly acid (salt), structure and its changes in the reaction, understand the catalytic role of heteropoly acid (salt) is significant. Studying and evaluating the thermal stability of the solid heteropolyacid (salt) structure is one of the most interesting issues in the field of heteropolyacid (salt) research. Here involves the secondary structure of heteropoly acid and heteropoly acid anion structure two issues. Due to limitations of previous studies on a single compound and a single method, the lack of heat to heteropoly acids has been lacking
