过氧化甲乙酮的热危险性研究

摘要本论文借助差示扫描量热仪DSC、快速筛选仪RSD和加速量热仪ARC等手段对过氧化甲乙酮的热危险性展开了初步研究。
首先，通过DSC实验对三种不同质量分数过氧化甲乙酮的热危险性进行定性分析，然后，通过RSD实验对过氧化甲乙酮进一步进行了定性分析，通过与DSC实验结果对比分析，初步得出过氧化甲乙酮的初始分解温度T0、峰值温度Tf、总放热量△Hd等基本热危险性参数，从而为之后的定量分析提供依据，使之能够顺利进行。最后，在ARC实验及分析方面，首先选择了适当的测试条件对三种不同质量分数的过氧化甲乙酮进行测试，之后用ARC自带的分析软件对ARC的实验数据进行了分析，得到三种不同质量分数过氧化甲乙酮的有关热力学参数，最后运用理论分析得出MEKPO的有关动力学参数，从而得出过氧化甲乙酮的热危险性的结论。8948
在上面得到参数的基础上推算了自加速分解温度SADT，从而为储存、运输等过程中过氧化甲乙酮的控制温度提供参考，减少事故的发生。

Title: The Thermal Hazards of Methyl Ethyl Ketone Peroxide
Abstract
This thesis was aimed to study The thermal hazards of methyl ethyl ketone peroxide (MEKPO) by using Differential Scanning Calorimetry (DSC), Rapid Screening Device (RSD) and Accelerating Rate Calorimeter (ARC).
After qualitatively analyzing on thermal hazard to the three different concentrations of MEKPO, further qualitative analysis of MEKPO was made by RSD. From tests preliminary conclusions can be obtained, which provide as basic data for quantitative analysis. Finally, ARC tests and analysis of MEKPO were taken in proper conditions, and experimental data were analyzed by using analysis software of ARC combining with special theories to get the thermodynamics and kinetic parameters of MEKPO in solution. Based on the parameters obtained by the three different calorimeters, the Self-Accelerating Decomposition Temperature (SADTs) of three different mass concentrations of MEKPO (40%, 45%, 52%) were calculated as 54.095℃, 52.226℃ and43.772℃ respectively. Therefore, the thermal decomposition danger of the three samples were decided as 52% MEKPO > 45% MEKPO > 40% MEKPO, which can provide as good guidance for manufacture, transport and storage.
