benzene+NO 3-benzeneUV photolysischemical reaction/ A8230F Ion-molecule, ion-ion, and charge-transfer reactions A8250 Photochemistry and radiation chemistryFrom the present experiments on the UV photolysis of aqueous nitric acid solutions containing benzene, it is inferred that nitrous acid is formed...
The vapor phase nitration reaction of benzene and chlorobenzene with NO2 on HZSM-5 catalyst and modified HZSM zeolite was studied, and the influence of temperatare, NO2/aromatic molar ratio, space velocity, water content, SiO2/Al2O3 ratiO and pretreatment temperature of HZSM-5 zeolite were dis...
Inphenol: Oxidation of isopropylbenzene Benzene is converted to isopropylbenzene (cumene) by treatment with propylene and an acidic catalyst. Oxidation yields a hydroperoxide (cumene hydroperoxide), which undergoes acid-catalyzed rearrangement to phenol and acetone. Although this ...
of the packed bed has an oxidative catalyst. Steam and oxygen are introduced at the center and will react with H2to generate heat that flows out of the core to the annulus. The shell side has the dehydrogenation catalyst, where the conversion of ethyl benzene to styrene takes place, ...
The hydroxyl group is attached to a benzene ring by the nucleophilic attack of water on the diazonium group. The chloride ion from diazonium salt can interfere in reaction by acting as a nucleophile. The anion of sulphuric acid helps to avoid reaction with chloride....
University of Tübingen, Tübingen, Germany INTRODUCTION Towards the end of the second World War we attempted the preparation of cyclohexanone-oxime (an important intermediate in the synthesis of Perlon) starting from cyclohexane-that means benzene as the basis, by avoiding the then scarce phenol basi...
The polyamine may also be an aromatic polyamine such as para-diaminobenzene, 4,4′-diaminophenylaniline, and the like. The polyamine may also be a ketone blocked polyamine, sometimes referred to as a ketimine, e.g., a polyamine, such as tetraethylenepentamine, may be reacted with a ketone...

For the oxidation of benzene derivatives, Pt/Al2O3 is generally used for benzene oxidation, whereas Pd/Al2O3 has been used for the oxidation of toluene (Diehl et al., 2015). Complete oxidation of benzene was achieved using a monolithic Mn/Ce-based catalyst incorporated on fibrous ceramic ...
Iminium ion scavengers are used in the invention to inhibit formation of N-nitrosamines, especially in cosmetics and pharmaceuticals formulations. The iminium ion scavengers may be used in combination with nitrite ion scavengers such as ascorbate. Inventors...
