过氧化环己酮储运热危险性评价

以过氧化环己酮(cyclohexanone peroxide,CYHPO)为研究对象,利用绝热加速量热仪(accelerating rate calorimeter,ARC)分析了CYHPO的自加速分解过程,采用速率常数法计算反应动力学参数.经过绝热修正,得到最危险状态下CYHPO的热危险评价参数,对其失控反应的本征热危险性进行评价.基于Semenov热爆炸理论,推算了最大反应速率时间(TMRad)、不归还温度(θNR)、自加速分解温度(SADT).计算表明可以忽略ARC仪器误差对推算结果的影响,推荐CYHPO储运采用25 kg以下的K型包装,储运温度控制在59.7℃以下.

Thermal Hazard Evaluation of Cyclohexanone Peroxide in Storage and Transport

The most serious thermal decomposition process of CYHPO (cyclohexanone peroxide) is investigated by accelerating rate calorimeter (ARC). The curves of thermal decomposition characteristic parameters versus time for the systems are obtained. The reaction kinetic parameters are calculated by the rate constant method. Modified by the thermal inertia factor， the temperature related parameters at the worst condition is obtained which can reflect the intrinsic thermal hazard of CYHPO. Based on reaction kinetic parameters and Semenov thermal explosion theory， the thermal hazard parameters such as TMR_ad， θ_NR， SADT， which are crucial in industry， are calculated. It is proved that the influence of instrumental error of ARC on the results can be neglected. The loading quality of CYHPO should not be exceeding 25kg and the optimal package is type K for this kind of package， the control temperature and emergency temperature should be lower than 59. 7℃.
