摘要
利用热重分析(TG)、差热分析(DTA)技术对钼酸铵的热分解进行了研究.研究表明,钼酸铵的热分解经历了3个步骤:在353~473K温区,脱除部分水分子,但仍保持钼酸铵的基本结构;在473~573K温区,脱除全部水分子和部分氨分子,生成一些亚稳钼物种;当温度高于573K时,脱除全部氨分子。
In this paper, infrared spectra of seventy kinds of cyclic quateranary ammonium derivatives are reported It was found that they all had two absorbing peaks in near 1000cm -1 and 900cm -1 These characterisities can be acted as important references to indentify this kind of compound
