AbstractProcesses of the multi-stage decomposition of maleic acid and Li, Na, and Cd maleates in an inert atmosphere are studied via thermal analysis with synchronous analysis of the composition of the released gases. Reaction mechanisms are proposed according to the data on the mass loss stages determined via thermal analysis, gaseous products, and the final solid decomposition products. It is shown that when
摘要通过热分析和释放气体组成的同步分析,研究了惰性气氛下马来酸与马来酸锂,钠和镉的多阶段分解过程。根据通过热分析,气态产物和最终固体分解产物确定的质量损失阶段的数据,提出了反应机理。结果表明,加热到700°C时,掺入多孔碳基质中的碳酸锂和碳酸钠是最终产品。高于350°C时,镉从氧化物还原为金属,并蒸发形成多孔碳残留物,这是唯一的热解产物。所有碳产物都是X射线无定形的。在133–239°C的温度下,马来酸完全分解成气态产物。
