【摘要】：自反應性化學物質(zhì)熱危險性評估的關鍵在于表征參數(shù)的選擇和量化,單一的評估參數(shù)往往僅表征其熱危險性的某一方面。綜合考慮自反應性物質(zhì)發(fā)生熱分解反應的難易程度及其造成后果的嚴重程度兩個方面,分別選取放熱反應初始溫度(To)和反應熱(-ΔH)作為相應的表征參數(shù),通過半正態(tài)分布函數(shù)對這兩個指標進行標準化處理。在此基礎上根據(jù)風險的定義提出了一種新的自反應性化學物質(zhì)的熱危險性綜合評估指數(shù)(THI指數(shù)),并建立相應的熱危險性分級標準,對自反應性化學物質(zhì)的熱危險性進行綜合評估與分級。結(jié)果表明,建立的THI指數(shù)所確定的熱危險性分級結(jié)果與基于活化能和最大絕熱溫度的RHI指數(shù)的反應危險性等級基本一致,該指數(shù)能夠?qū)ψ苑磻曰瘜W物質(zhì)的熱危險性進行定量評估。
[Abstract]:The selection and quantification of characterization parameters are the key to the thermal hazard assessment of self-reactive chemicals. A single evaluation parameter often represents only one aspect of its thermal hazard. It takes into account both the difficulty of the thermal decomposition reaction of a self-reactive substance and the severity of its consequences, The initial temperature of exothermic reaction (Too) and the reaction heat (H- 螖 H) were selected as the corresponding characterization parameters, respectively. The two indexes are standardized by semi-normal distribution function. Based on the definition of risk, a new comprehensive assessment index of thermal hazard of self-reactive chemicals is proposed, and the corresponding Thi index is established. Thermal hazard classification standard, The comprehensive assessment and classification of the thermal hazard of self-reactive chemical substances are carried out. The results show that the thermal hazard classification determined by the established THI index is basically consistent with that of the RHI index based on the activation energy and the maximum adiabatic temperature. The index can quantitatively assess the thermal hazard of self-reactive chemicals.
