“…The tert-Butyl hydroperoxide (TBHP) induced oxidation process has also been studied by Singh et al [141] using the Co-HMS through the heterogenization of cobalt acetylacetonate; they demonstrated 49% conversion but with the sacrificed selectivity of 60% to AP. Jermy et al [142] obtained 53.9% conversion and 81.3% selectivity to AP on the catalyst of highly ordered three-dimensional V-SBA-16 and a plausible reaction mechanism is shown in Figure 17. To our delight, the big breakthrough towards the oxidation of ethylbenzene using a magnetism-responsive Fe 3 O 4 @SiO 2 -NH 2 @CS-Co(II) has been reached by Zhai et al [143].…”

Ordered mesoporous silicas (OMSs) attract considerable attention due to their advanced structural properties. However, for the pristine silica materials, the inert property greatly inhibits their catalytic applications. Thus, to contribute to the versatile surface of OMSs, different metal active sites, including acidic/basic sites and redox sites, have been introduced into specific locations (mesoporous channels and framework) of OMSs and the metal-functionalized ordered mesoporous silicas (MOMSs) show great potential in the catalytic applications. In this review, we first present the categories of metal active sites. Then, the synthesized processes of MOMSs are thoroughly discussed, in which the metal active sites would be introduced with the assistance of organic groups into the specific locations of OMSs. In addition, the structural morphologies of OMSs are elaborated and the catalytic applications of MOMSs in the oxidation of aromatic compounds are illustrated in detail. Finally, the prospects for the future development in this field are proposed.

“…Catalytic oxidation of ethylbenzene in the liquid phase is a commercially significant reaction. The key products obtained by ethylbenzene oxidation are acetophenone and benzaldehyde in the presence of oxidizing agent and homogeneous/heterogeneous catalysts . Acetophenone (viscous colorless liquid) is a meaningful intermediate material for the manufacturing of pharmaceuticals, resins, drugs, alcohols, perfumes, esters, aldehydes, flavoring agent in many drinks, and solvents …”

Polymer-silica hybrid support was synthesized, and Cu (II), Co (II), Mn (II), and Ni (II) metals were loaded over hybrid support by incipient impregnation method. Oxidation of ethylbenzene was performed for catalytic evaluation of catalysts at different reaction conditions, that is, the mole ratio of ethylbenzene to TBHP and reaction temperature. The main reaction product was acetophenone along with benzaldehyde as the minor product. The highest ethylbenzene conversion (96.5%) was attained at a 1:3 mole ratio of ethylbenzene to TBHP and temperature at 100 C. Activation energy and reusability of the catalysts were also determined, and results showed that they can be easily reused three times without much loss in their structural and catalytic properties.

“…The high silica zeolites are hydrophobic in nature, while low silica zeolites are more hydrophilic. Zeolites have found widespread application as adsorbents, ion exchange materials, detergent builders and catalysts, especially in petroleum refining, petrochemicals and fluidized catalytic cracking (Moon et al, 2008;Zhang et al, 2011;Dalil et al, 2012;Jermy et al, 2011;Saceda et al, 2012;Induri et al, 2010;Lee et al, 2009;Gaur et al, 2010).…”

-The separation of p-xylene and m-xylene from C8 aromatic hydrocarbon feed using Y zeolites is investigated. Effect of residual moisture on p-xylene adsorption on BaY was measured in order to optimize the activation temperature of the adsorbent. The results show that with an increase in temperature the moisture on the adsorbent decreases. An optimum loading of moisture is required for adsorption of xylene on the adsorbents. The Everett equation is used to determine the adsorption capacity and selectivity. It has been found that the adsorbents best suited for the separation of p-xylene, m-xylene, o-xylene and ethyl benzene from the mixture of C8 aromatics are NaY, NaY, BaY and KY, respectively. The XRD results show that the crystallinity of the adsorbent decreases upon exchanging the zeolites to K + and Ba 2+ ions.
