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 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 کاملDeep Eutectic Solvent Based on Choline Chloride/Urea as an Efficient Catalytic System for the One-Pot Synthesis of Highly Functionalized 1,4-Dihydropyridines and Polysubstituted 4H-Chromenes
One-pot four-component synthesis of polyfunctionalized 1,4-dihydropyridine derivatives was developed by a condensation of aldehydes, malononitrile, diethylacetylenedicarboxylate and aniline in the presence of choline chloride/urea as a deep eutectic solvent (DES)at room temperature.Moreover, an efficient method was reported for the synthesis of highly substituted 4H-chromenes through one-...
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 کاملCatalytic Conversion of Carbohydrates to Furanic Derivatives in the Presence of Choline Chloride
The synthesis of furanic derivatives (5-hydroxymethylfurfural (HMF), furfural . . . ) from carbohydrates is of high interest for a wide range of applications. These reactions are carried out in the presence of various solvents, and among them choline chloride can be used. It is a salt that can form a low melting mixture with a carbohydrate (fructose, glucose . . . ) or a deep eutectic mixture w...
