摘要
用半固相反应法合成了苯甲酸铜,用热重分析法(TG、DTG)研究了它在氮气气氛中的热分解过程,并用X-射线粉末衍射进行结构表征.苯甲酸铜的分解过程分二步进行,第一步失重23.7%;第二步失重29.0%,主要产物有二苯甲酮、联苯酰、氧化铜等.
Copper benzoate was synthesized by semi-solid phase reaction and its structure characterized.The mechanism of thermal decomposition for copper benzoate was studied by TG,DTG and XRD techniques,The thermal decomposition of copper benzoate in nitrogen atmosphere proceeded in two stages.23.7%weight loss occurred at the first stage and 29.0%at the second stage.Compounds formed from decomposition reaction were mainly benzophenone,benzyl and copper oxide.
