Cumene hydroperoxide‐initiated radical polymerization
Journal of Polymer Science, 1961AbstractThe initial rates of solution polymerization of styrene and methyl methacrylate initiated by cumene hydroperoxide were determined at several temperatures. A new method of analysis of the kinetic data is presented. The results led us to conclude that the radicals which initiate polymerization are produced exclusively by bimolecular reactions ...

The treatment of cumene hydroperoxide containing wastewaters
1997Cumene hydroperoxide (CHPO) is the noxious environmental pollutant whose toxicity is determined both by hydroperoxide and aromatic structures. It is released in the environment with wastewaters of phenol production by the cumene method, of rubber and polymer synthesis and of other chemical plants.

Abstract Cumene hydroperoxide dissolved in dodecane is rapidly decomposed by platinum and appreciably by silica gel or by silver in the absence of gaseous oxygen, but virtually no decomposition is observed with unsupported silver in an oxygen atmosphere.

This article presents direct evidence of the occurrence of cumene oxidation resulting from the presence of gaseous oxygen (O2gas) at the gas-liquid interface, demonstrating a markedly higher magnitude of process selectivity, as compared to oxidation that is promoted by dissolved oxygen (2liquid).

Oxidation of cumene to hydroperoxide in the presence of platinum
Journal of Catalysis, 1980Abstract The catalytic action of platinum in the oxidation of cumene to cumene hydroperoxide has been studied at a temperature of 110–120 °C, a flow rate of the oxidizing air of 1.6 × 10−2 m3/kg s, a contact time of 60 to 360 min, and an initial content of the initiator (cumene hydroperoxide) from 2 to 5%.

Matrix effect on the radiolysis of cumene hydroperoxide
Journal of Radioanalytical and Nuclear Chemistry Letters, 1988The radiolysis of the cumene hydroperoxide in polymers /PS, PMMA/ on one hand, and in matrix of organic molecules with low molecular weight on the other hand shows the impact of both the chemical structure and the physical state on the dispersed phase in the matrix.

Catalytic decomposition of cumene hydroperoxide into phenol and acetone
Applied Catalysis A: General, 2001Abstract The decomposition of cumene hydroperoxide (CHP) was carried out in a batch reactor over supported solid acid catalysts, acid-activated montmorillonite K10 (Mont. K10) and metal-ion-exchanged (Mont. K10), at 30–60°C. The products were phenol and acetone. Supported dodecatungstophosphoric acid (DTPA) showed 100% conversion within 5 min at 30°C;

The chromium-stearate-catalyzed decomposition of cumene hydroperoxide
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19771. A study has been made of the kinetics of the chromium-stearate-catalyzed decomposition of cumene hydroperoxide, and of the composition of the products obtained. 2. Decomposition to free radicals and molecular products proceed in parallel, but through different mechanisms.

p-(Chloro-tert-butyl)cumene hydroperoxide
Russian Chemical Bulletin, 1998Oxidation of a mixture ofm- andp-(chloro-tert-butyl) cumenes (12:88) by molecular oxygen gives onlyp-(chloro-tert-butyl)cumene hydroperoxide in a high yield; this product can be used for the synthesis of the pyrethroid ethofenprox.
