Autocatalytic Decomposition of Cumene Hydroperoxide at Low Temperature Conditions
Cumene Hydroperoxide (CHP) has been used in the production of Dicumyl Hydroperoxide (DCPO) and phenol. In Taiwan, several severe fire or explosion incidents have occurred due to its thermal instability or reactivity. In this research, the exothermic decomposition of CHP in Cumene was characterized by isothermal microcalorimeter, TAM (thermal activity monitor), because isothermal testing offers ...
متن کاملThermal hazard assessment on hydroperoxides-examples on cumene hydroperoxide
Distributed Multimedia Information System Laboratory School of Computer Science, Florida International University Miami, FL 33199, USA Abstract Since the nineteenth century, the chemical process industries have developed rapidly not only in terms of degree of complexity and throughput, but also in potential hazards. Such hazards exist when chemicals undergo decomposition, polymerization or othe...
متن کاملRunaway Prevention in Cumene Hydroperoxide Storage Tanks
In this work thermal runaway of cumene hydroperoxide (CHP) in a storage tank with constant jacket temperature is considered. The divergence method developed by Strozzi and Zaldivar (1994) based on the concept of parametric sensitivity and a runaway criterion focused on a set of critical parameters identified by Velo et al. (1996) have been applied to our system. The results obtained from the co...
متن کاملThermal Hazard Evaluation of Cumene Hydroperoxide-Metal Ion Mixture Using DSC, TAM III, and GC/MS.
Cumene hydroperoxide (CHP) is widely used in chemical processes, mainly as an initiator for the polymerization of acrylonitrile-butadiene-styrene. It is a typical organic peroxide and an explosive substance. It is susceptible to thermal decomposition and is readily affected by contamination; moreover, it has high thermal sensitivity. The reactor tank, transit storage vessel, and pipeline used f...
متن کاملEffect of CO2 Partial Pressure on the Thermal Decomposition Kinetics of Zinc Carbonate Hydroxide (TECHNICAL NOTE)
In this work, the effect of carbon dioxide partial pressure on the calcination kinetics of high purity zinc carbonate hydroxide has been studied. Non-isothermal analysis has been performed on samples at different CO2 partial pressures by TGA and DTA. It has been found that the calcination behaviour of this material corresponds to the shrinking core model and the reaction mechanism is phase boun...
