In this thesis, investigations focused on heteropoly acids-catalyzed C-C and C-N bond formation reactions and the synthesis of xanthenediones and acridinediones under thermal conditions are described.1.12-Phosphotungstic acid has been used as an efficient,eco-friendly,and air- and moisture-stable catalyst to promote the direct dehydrative substitution of the hydroxy group of benzylic and allylic alcohols with variousβ-dicarbonyl compounds.

本篇论文主要描述了杂多酸催化下的C-C和C-N键的生成，以及无溶剂直接加热下合成十氢氧杂蒽二酮和9-芳基十氢吖啶二酮。主要内容如下：1。在磷钨酸催化下，1，3-二羰基化合物与醇能够顺利偶合，脱除一分子的水，生成烷基化的1，3-二羰基化合物。反应在甲苯中进行时，二芳基甲醇能与各类1，3-二羰基化合物反应，成率很高；但对于1-苯乙醇，只能得到很低的产率。

Among the organophosphorus flame retardants, caged bicyclic phosphates have been in greatfavor, and many investigations have been done about them. It is found that caged bicyclicphosphates and their derivatives can serve as effective flame retardants to some polymers.

以季戊四醇为基的双环笼状磷酸酯及其衍生物兼具丰富的碳源和酸源，与三聚氰胺等配合使用可发挥良好的膨胀阻燃作用，因此它们的合成和应用倍受研究者的关注。

It is shown that deformation temperature is the main factor that influences the static recrystallization behavior. Carbonitride precipitation inhibits recrystallization and causes a plateau in the softening ratio curve. The static recrystallization activation energy of X80 pipeline steel was regressed and calculated to be 380 kJmol^(-1), and its rationality was also discussed according to previous references and investigations.

结果表明：变形温度是影响奥氏体静态再结晶行为的主要因素；微合金碳氮化物的析出抑制了再结晶的进行，使软化率曲线出现了平台；利用实验结果回归计算出了X80管线钢的静态再结晶激活能为380kJmol^(-1)，并根据文献研究讨论了结果的合理性。
