Thermal hazard analysis for cumene hydroperoxide by DSC and TAM

摘要

Since the 1980s, hazards arising from reactive chemicals have been investigated with a variety of instruments and even exotic approaches. Among numerous chemicals, considerable attention has been given to unstable mixtures or intermediates used in the chemical industries because of their potential hazards. To reduce any unexpected risks, one must choose appropriate calorimeters to analyze reactive chemicals or their incompatibilities. In principle, calorimeters not only have to have different functions but also be versatile in operation and application. In this study, Cumene Hydroperoxide (CHP), areactively unstable organic peroxide, was investigated for its inherent hazardous characteristics by two commonly used calorimeters, Differential Scanning Calorimetry (Mettler Toledo 821°) and Thermal Activity Monitor (2277 Thermal Activity Monitor). Advantages and disadvantages of both calorimeters specifically used for the thermal hazard analysis for CHP were also discussed. Ultimately, the objective is to make extensive and long-term contributions to safer process design as well as to enhance safety technology during the preparation, processing, storage, transportation, or even disposal periods.
