WebThe interactions between M–N–C and cumene, O2, and CHP are fully investigated. There are strong interactions between FeNC/CoNC and O2, cumene, and CHP, in which the activation of cumene and O2 and the decomposition of CHP occurred more easily, thereby promoting the catalytic activity. Although the adsorption energy over CuNC (ΔECuNC) for ... WebApr 1, 2024 · Initial concentrations: cumene [Cmn] 0 = 7 mol/L, cumene hydroperoxide [CHP] 0 = 0.236 mol/L, dimethyl phenyl carbinol [DPhC] 0 = 0.033 mol/L, acetophenone [APh] 0 = 0.007 mol/L, formic acid [FA]0 = 0 mol/L (hereinafter, the designation in square brackets means the species concentration, the index 0 refers to the initial time of the …
Selective Oxidation of Cumene to the Aquivalent of …
WebJan 14, 2024 · The oxidation of cumene and following cleavage of cumene hydroperoxide (CHP) with sulfuric acid (Hock rearrangement) is still, by far, the dominant synthetic route to produce phenol. In 2024, the global phenol market reached a value of 23.3 billion US $ with a projected compound annual growth rate of 3.4% for 2024–2025. Webtemperature were all detrimental to the production of CHP from cumene. Studies of the reaction kinetics revealed that the activation energy of the reaction (E) is around 38.9 × 104 kJ mol–1. The low apparent acti vation energy of the reaction could explain why the rate of cumene oxidation to CHP in the presence of met chase offshore banking
