Thermal risk analysis of cumene hydroperoxide in the presence of alkaline catalysts

Thermal runaway behavior and hazard evaluation of cumene hydroperoxide mixed separately with four products under adiabatic conditions coupled with risk matrix method

“…13,[15][16][17] Some accidents of OPs in recent decades are listed in Table 1. [5][6][7][8][9][10][11]18,19 The occurrence of chemical accidents is mainly due to the thermal behavior and reaction characteristics of hazardous substances that are not understood by the operators, which indicated that basic experiments are necessary, and comprehensive thermal hazard analysis is a prerequisite to ensure the safety of chemical production. 3,8,12,18,19 In recent decades of research, many scholars have carried out plentiful works: Wang et al addressed a dynamic and systematic method to estimate the effect of incompatibilities on thermal runaway hazard of CHP.…”

“…[7][8][9][10][11][12][13][14][15][16][17][18] Duh et al reviewed the published kinetic parameters on the thermal decomposition of CHP in cumene and discussed the importance of obtaining reliable and accurate chemical kinetic range for the safety and engineering application of CHP-related processes. 12 F I G U R E 1 Production process of cumene hydroperoxide (CHP) and its products [5][6][7][8][9][10][11] T A B L E 1 Selected chemical accidents caused by organic peroxides (OPs) in recent decades [5][6][7][8][9][10][11]19,20 method by calorimeters and thermal safety software. 20 Based on summary and analysis of research status, thermal stability, incompatibility, and decomposition mechanism of CHP have studied a near full-scale exploration.…”

“…However, the exothermic decomposition process of OPs in production preparation, transportation, and storage needs intrinsically safer design because they can release large amounts of heat and results in high pressure in uncontrolled conditions, leading to a fire or an explosion. [1][2][3][4][5][6] Cumene hydroperoxide (CHP) is a representative OP and an important intermediate in the petrochemical industry. It is usually produced in the oxidation of cumene and broadly used in industrial fields, as an initiator of free radicals polymerization used universally to produce the acrylonitrile-butadiene-styrene resin and the curing agent in the petrochemical industry with unsaturated monomers.…”

Certainly, the thermal decomposition reaction of CHP conforms to a flexible, intricate, and self-accelerating decomposition model, and that is noticeable to consider the self-heating effect due to its products.…”
