【摘要】：采用RC1e反应量热仪对过氧化苯甲酰(BPO)合成工艺危险性进行研究,测试不同Na OH溶液初始浓度(1.96 mol/L、3.93 mol/L、7.14 mol/L)下反应的放热历程,获得BPO合成反应过程中的热危险性参数,并采用PHI-TECⅡ绝热加速量热仪对产物进行热稳定性分析,最后评估该反应热风险。结果表明,Na OH浓度为7.14 mol/L时,反应初期放热速率慢,热累积度大,后期反应剧烈,绝热温升(ΔTad)及热失控时工艺反应达到的最高温度(MTSR)最大。热稳定性试验表明,合成的粗产物BPO初始分解温度、活化能、指前因子、最大放热速率到达时间为24 h时的对应温度(TD24)均低于纯BPO。利用合成粗产物BPO的TD24对反应进行危险度评估,该工艺热危险性等级均为5级,工艺危险性大。
