WebMechanism: M, NH3 M, NH3 (X = R, OR, NR2) (rate-limiting step) Electron-Donor Substituents (X): • Protonation of cyclohexadienyl anions is kinetically controlled and occurs at the central carbon. • Regioselectivity of protonation steps in the Birch reduction: • Reductions of alkyl benzenes and aryl ethers require a ortho protonation meta ... WebMay 15, 2009 · The results of theoretical research on reaction mechanism show that there is a dominant reaction pathway, which consumes most of the CHP in decomposition reaction. This conclusion agrees with the experimental results that 40 wt% is a critical point for almost all important parameters of runaway reactions. chronic prostatitis in dogs
Cumene - Wikipedia
The cumene process (cumene-phenol process, Hock process) is an industrial process for synthesizing phenol and acetone from benzene and propylene. The term stems from cumene (isopropyl benzene), the intermediate material during the process. It was invented by R. Ūdris and P. Sergeyev in 1942 … See more Cumene is formed in the gas-phase Friedel–Crafts alkylation of benzene by propene. Benzene and propene are compressed together to a pressure of 30 standard atmospheres at 250 °C in presence of a See more • Phenol -- The essential chemical industry online See more Alternatives to acetone co-production Cyclohexylbenzene can replace isopropylbenzene.
