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( lionet)作为反应可能性指
数(RPI),最大功密度(MPD)(包含反应热(ム)和最大反应速率max(dr/d))、绝热温升(ムT。)、最大压力上
升速率max(dp/d)和总压力変化(△P)等参数通过层次分析法综合为反应严重度指数(RS),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(RS)中的权
重。将RP指数与RS7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(OP
IC)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

Abstract In this aper, a new classification method of organic peroxides instability hazards(OPC)was proposed through studying
several classic instability classification methods at home and abroad. In this method, exothermic onset temperature(Tonset )was set
as reaction probability index(RP), Maximum power ensi(MPD (include heat of reaction(A)and maximum reaction rise rate
(max(d/d ) adiabatic temperature rise(A) maximum pressue se ae(max( otal pressure changes(AP)were in-
tegrated into reaction severity index(RS/) based on analytic hierarchy process(AHP). The weights of AHP were obtained by previ
ous statistics. The final classification of organic peroxide instability was achieved by The RPI and Rsr combined with risk matrix
method. The OPC method could be more comprehensive characterization of liquid organic peroxides instability. The results of OPIC
ethod based on vent sizing package 2( SP2 )experiment were more real than the results calculated by old method, and could pro
vide reliable technical supports for inherent safety of chemicals
Key words: instability classification; vent sizing package 2( SP2 );organic peroxides; inherent safety
