【摘要】：本文通过对国内外危险化学品不稳定性分级进行研究,提出了一种新的有机过氧化物不稳定性分级方法(OPIC),此方法基于泄放尺寸包绝热量热仪(VSP2)测量数据,将反应初始温度(Tonset)作为反应可能性指数(RPI),最大功密度(MPD)(包含反应热(ΔH)和最大反应速率max(dr/dt))、绝热温升(ΔTad)、最大压力上升速率max(dp/dt)和总压力变化(ΔP)等参数通过层次分析法综合为反应严重度指数(RSI),并将前人统计的采用这些参数准确分级的次数代入层次分析法(AHP)中,得到这些参数在反应严重度指数(RSI)中的权重。将RPI指数与RSI指数采用风险矩阵的方法得到最终的有机过氧化物不稳定分级,能更加全面的表征有机过氧化物的不稳定性。根据VSP2实验和计算结果分析证明:利用本文提出的有机过氧化物分级方法(OPIC)对液体有机过氧化物进行分级更符合实际情况,该方法为化学品的本质安全筛选提供了可靠的技术支持。
[Abstract]:In this paper, a new method of classifying the instability of organic peroxides (OPIC),) is proposed, which is based on the measurement data of release size package adiabatic calorimeter (VSP2). The initial reaction temperature (Tonset) was used as the (RPI), maximum work density (MPD) (), which included reaction heat (螖 H) and maximum reaction rate (max) (dr/dt), adiabatic temperature rise (max (dp/dt) and total pressure change (螖 P) by analytic hierarchy process (AHP). In this paper, the index of response severity (RSI),) is added to the analytic hierarchy process (AHP), and the number of accurate classification using these parameters is added to the AHP (AHP). The weights of these parameters in the response severity index (RSI) are obtained. The RPI index and RSI index are used to obtain the final classification of the instability of organic peroxides, which can be used to characterize the instability of organic peroxides more comprehensively. According to the analysis of VSP2 experiments and calculation results, it is proved that the classification of liquid organic peroxides by using the organic peroxide classification method (OPIC) proposed in this paper is more suitable for the actual situation. This method provides reliable technical support for chemical essential safety screening.
