However, the drawbacks of the three-step cumene process have spurred the development of more economical routes to decrease energy consumption, avoid the formation of explosive cumene hydroperoxide, and increase the yield. The objective of this article is to highlight benzene-to-phenol conversion ...
Benzene conversion to phenolThe one-step conversion of benzene to phenol in a photocatalytic membrane reactor (PMR) coupling simultaneous reaction and product separation by means a membrane contactor is reported. The effects of parameters such as pH of aqueous TiO 2 suspensions, initial amount of ...

79 The particular examples that have been used to demonstrate this polymerization reaction include the synthesis and polymerization of 4,4′-bis(1-naphthoxy)biphenyl, 2,2′-bis(l-naphthoxy)biphenyl, 3,3′-bis(1-naphthoxy)biphenyl, and 1,3-bis(1-naphthoxy)benzene in nitrobenzene with FeCl3...
Benzene is converted to isopropylbenzene (cumene) by treatment withpropyleneand an acidiccatalyst. Oxidationyieldsa hydroperoxide (cumene hydroperoxide), which undergoes acid-catalyzed rearrangement to phenol andacetone. Although this process seems more complicated than the Dow process, it is advantageous ...

Also known as carbolic acid or monohydroxybenzene, phenol is a colorless to white crystalline material of sweet odor, having the composition C6H5OH, obtained from the distillation of coal tar and as a by-product of coke ovens. Phenol has broad biocidal properties, and dilute aqueous solutions...
Phenol has a hydroxyl group (OH) attached to a six–carbon atom benzene (aromatic) ring. The electron-rich aromatic ring makes phenol important in electrophilic aromatic substitution with oxidation reactions. Sign in to download full-size image Figure 4.1. Chemical structure of phenol and its by...
A mechanism-exploration experiment was carried out and showed that the strong binding effect between the surface of the Ru/Nb2O5-nC18PA catalysts and the benzene ring allows the aromatic ring in phenol to be hydrogenated, increasing the selectivity to cyclohexanol. This biphasic catalytic system ...
A method and a catalyst are described for selective oxidation of aromatic compounds (e.g., benzene and its derivatives) into hydroxylated aromatic compounds (e.g., corresponding phenols). For example,
