    Infrared spectroscopy was used to obtain information on the mechanism of the selective oxidation of toluene and o-xylene over vanadium oxide catalysts. The interaction of these aromatic hydrocarbons and the products benzaldehyde and o-tolualdehyde with the surface of a V2O5/TiO2 monolayer catalyst was investigated at different temperatures. phase selective oxidation of hydrocarbons over a solid catalyst. Benzene, n-butane, and butenes are used. Recovery of maleic anhydride as a by­ product from phthalic anhydride manufacture provides small commercial amounts. In general, the production of maleic anhydride from hydrocarbons .   Bifunctional catalysts for conversion of hydrocarbons contain metal sites next to acid sites. In the case of conversion of normal alkanes, the metal sites catalyze (de-)hydrogenation reactions and the acid sites isomerization and cracking reactions to obtain iso-alkanes of the same or reduced molecular weight, respectively Critical properties of these catalysts are the ratio of metal sites. Oxidation Catalysis”, edited by Daniel Duprez and Fabrizio Cavani, aims to give an overview of catalytic oxidation methods. It is divided in two parts, covering total and selective oxidation, and draws on the experience of a number of academic and industrial scientists. It is a broad and generally useful book.

    Selective oxidation catalysis is used in production of roughly 25% of all important organic chemicals and intermediates used for making consumer and industrial products [1]. . The abundance of natural gas from shale resources makes efficient catalytic oxidation of light hydrocarbons to more valuable intermediates particularly desirable.

Selective oxidation of hydrocarbons [Hucknall, D. J] on *FREE* shipping on qualifying offers. Selective oxidation of hydrocarbonsCited by: Additional Physical Format: Online version: Hucknall, D.J. Selective oxidation of hydrocarbons. London, New York, Academic Press, (OCoLC) A catalyst for the selective oxidation of hydrocarbons to unsaturated aldehydes, acids, acid anhydrides, divinyls, or styrenes has to perform several functions.

First, it must supply a limited amount of oxygen to the reactant, sufficient to allow the formation of the desired product but not enough to allow complete by: Selective oxidation of hydrocarbons is a very important industrial process that uses catalysts commonly based on transition metal oxides that are often vanadium and molybdenum oxides.

Selective oxidation reactions can be classified into two types: those that involve only dehydrogenation and those that involve both dehydrogenation and oxygen. Cite this chapter as: Mizuno N., Hashimoto M., Sumida Y., Nakagawa Y., Kamata K.

1. Introduction. It has been well documented that supported Au particles can be very active oxidation catalysts.

The most well-known of these reactions is low temperature CO oxidation, but others, such as oxidation of hydrogen to hydrogen peroxide and selective oxidation of hydrocarbons including epoxidation of propene and oxidation of propane to acetone are also firmly.

selective oxidation. Another strongly prevailing principle is that of phase cooperation [10–13]. This states that high-performance oxidation catalysts must be of the multi-phase type, as the different functions required in performing the selective oxidation of a hydrocarbon are only adequately optimized when independent functionally.

The chapter also discusses recent developments including selective oxidations with environmentally benign oxidants, green oxidations with metal complexes, chemoselective C‐H bond oxidations, asymmetric oxyfunctionalizations, and oxygenation of hydrocarbons in tandem processes with in situ generated H 2 O 2.

The selective oxidation of light hydrocarbons, especially propylene, is the most significant and well-studied process. Its products include important intermediates such as acrolein, acrylic acid, propylene oxide, etc.

The catalytic process was first discovered in by Hearne and Adams with the use of cuprous oxide catalysts. The activation of C–H bonds is an efficient approach for the production of value-added organics. The partial oxidation of hydrocarbons to oxygen-containing products at mild conditions is a profound challenge because the products are often more active than the substrates.

Abstract. The Gif system 1,2 for the selective oxidation of saturated hydrocarbons consists of pyridine (as solvent), acetic acid (or other carboxylic acid), zinc powder (as source of electrons), oxygen and an iron salt as catalyst.

The iron salt is rapidly complexed with ortho-dlpyrldyl (produced by reduction of pyridine).This system is interesting because it oxidizes hydrocarbons selectively.
