【摘要】 用流变相反应法合成了二水邻苯二甲酸镁。通过元素分析、X射线粉末衍射、红外光谱确定了它的组成和晶体结构,它为层状结构,属单斜晶系。用TG和DTA研究了它在氮气中的热稳定性,并用GCMS、XRD表征了热分解产物。二水邻苯二甲酸镁在氮气中热分解分为两步:先失去两个结晶水,最终产物为氧化镁。生成的气相凝聚物成分比较复杂,主要是二苯甲酮、蒽醌。更多还原

【Abstract】 Magnesium phthalate dihydrate was synthesized by rheological phase reaction.The constituents and crystal structure were determined by XRD,IR,DTA,TG,etc.Its thermal decomposition mechanism in N₂ was studied by TG,DTA.The thermal decomposition products were characterized by XRD,GC-MS.The thermal decomposition of magnesium phthalate dihydrate in N₂ proceeded in two stages,it first lost two molecules of crystal water to form anhydrous salt,then magnesium phthalate decomposed further,the final product was MgO.The organic compounds were mainly benzophenone and anthraquinone.更多还原
