The criterion of critical runaway and stable temperatures in cumene hydroperoxide reaction

Kinetic parameter estimation for decomposition of organic peroxides by means of DSC measurements

“…These latter are widely used in the plastic and rubber industries because they are a source of free radicals which initiate a number of polymerization reactions (Luo et al, 2001). The organic peroxides are renowned by their thermal instability and their explosive character.…”

The criteria of critical runaway and stable temperatures of catalytic decomposition of hydrogen peroxide in the presence of hydrochloric acid

“…Leung have developed emergency venting requirements of a runaway reaction system with gas generation using an aqueous hydrogen peroxide decomposition example [10]. We have previously evaluated the critical condition and stability criterion in decomposition reaction of hydrogen peroxide with its initial concentrations as 7.5, 15 and 30 wt.%, respectively [11]. In this paper, we found that the decomposition reaction of hydrogen peroxide with low concentration is a tempered hybrid system,…”

“…The evaluations of kinetic parameters were incorporated with Semenov's sufficient and necessary conditions of thermal explosion to determine the critical runaway reaction temperatures and stable criteria [7][8][9][10][11][12][13][14][15][16][17][18][19]. The requirements of heat transfer coefficient in the critical conditions can also be estimated.…”

Reactions of cumene hydroperoxide mixed with sodium hydroxide

“…It may result in fire or explosion from contact with thermal sources, acid-catalyzed, base-catalyzed, metallic compounds, pollutants, and mechanical impact, etc. [1][2][3]. Based on the above-mentioned, organic peroxides are very unstable and active materials.…”

“…Additional applicable purposes include use as a catalyst, a curing agent, and as an initiator for polymerization. CHP is an initiator for polymerization to produce the acrylonitrile-butadiene-styrene (ABS) resin [3], and is also a source material for producing dicumyl hydroperoxide (DCPO) by dehydration process in Taiwan and around the world. In the manufacturing process of DCPO, CHP is catalyzed by dilute about 45 mass% NaOH to yield ␣-cumyl alcohol (also called dimethylphenyl carbinol, DMPC) [5].…”
