摘要
用DTA和TG研究了碱土金属苯甲酸盐在氮气气氛中的热分解过程 ,并用红外光谱、色 -质联用表征了热分解产物。碱土苯甲酸盐在氮气中一步或两步分解生成碳酸盐或氧化物和有机化合物 ,有机化合物的成分主要是二苯甲酮和三苯甲烷等。
The mechanism of thermal decomposition for alkaline earth metal benzoates was studied by using TG,DTA,IR and gas chromatography_mass spectrometer.The thermal decomposition of the alkalline earth benzoates in nitrogen proceeded in one or two stages,they decomposed to form MgO,MCO 3(Ca,Sr,Ba) and organic compounds.The organic compounds obtained from the first step reaction are mainly benzophenone,triphenylmethane and so on.
