一种计算最大反应速率到达时间的新方法
A new method for calculating time to maximum rate under adiabatic condition
摘要
Abstract
Time to maximum rate under adiabatic condition (TMRad) is a widely-used parameter for evaluation of the probability of decomposition reactions of substances or reactive mixtures under adiabatic conditions.The traditional method for calculation of TMRad necessitates the kinetics and thermodynamics of the decomposition reactions,such as pre-exponential factor,activation energy,reaction order and decomposition enthalpy.To calculate the TMRad using accelerating rate calorimeter (ARC),a whole thermal curve including both onset decomposition temperature and final temperature is required.However,due to the complexity of reaction mechanism or safe operation of calorimetric experiment,the final temperature is often unavailable,meaning the traditional method is in failure.Therefore,to solve this problem,this paper proposes a new method for calculating TMRad,which is based on the assumption that the consumption of reactants is negligible within a narrow temperature range relative to the whole exothermic curve.Moreover,the experiment results also prove the flexibility of this new method to exothermic curve including final temperature.关键词
