Results of a Round-Robin with di-tertiary-butyl peroxide in various adiabatic equipment for assessment of runaway reaction hazards

The results of a Round-Robin test on the decomposition reaction of 15% w/w di-tertiary-butyl peroxide (DTBP) in toluene are described in the present paper. The aim of the Round-Robin test was to compare the results of different (pseudo-)adiabatic reaction calorimeters in terms of accuracy and reliability for practical applications. The experiments were performed in the Accelerating Rate Calorimeter (ARC), Phi-Tec, Pressure Dewar calorimeter (Dewar), temperature controlled reactor (CRVM) and the Automatic Pressure Track Accelerating Calorimeter (APTAC). Although the various types of equipment showed differences in accuracy and reproducibility, in general, no specific type of equipment seems to out-perform the others in the present study.
