Cumene on reaction with oxygen
Did you know?
WebCumene (isopropylbenzene) is oxidised in the presence of air to produce cumene hydroperoxide. Phenol is produced by further treating cumene hydroperoxide with dilute acid. One of the by-products of this process is the production of acetone in large amounts. Therefore, it is necessary to purify the phenol that results from these processes. 2. WebA study was made on the effect of Ca, Sr, and Ba chloride complexes with dibenzo-18-crown-6 ether as catalysts on the process criteria of the efficiency of industrial cumene oxidation using kinetic modeling. It is the first stage in the process chain of polymer composite production. The kinetic scheme of the process is made of classical reactions …
WebDec 13, 2013 · The rate constants of reaction of cumene with oxygen in the absence of catalyst or photoinitiator was deduced by Ikawa et al. , for the reaction RH → R •, to be … WebNov 10, 2011 · The effect of substitution on the ligand was also monitored in both oxygen-absorption and the catalytic reaction. Based on these results, the trend observed for the production of α-methylstyrene and cumyl alcohol were parallel to dioxygen uptake by the catalyst in neat cumene, while acetophenone productions obeyed a non-linear trend.
Webin the meta example, the benzene carbon that is attached to the oxygen already has four bonds (one single bond to the oxygen, one single bond to another carbon in the ring, and a double bond to a second carbon in the ring). That is, that carbon already has a full octet so can't accept any more electrons to form a double bond with oxygen. http://colapret.cm.utexas.edu/courses/Chapter%2024-benzos.pdf
