Book Description

The Oxidation of Cyclohexane focuses on the processes, methodologies, reactions, and approaches involved in the oxidation of cyclohexane. The publication first offers information on the theory of slow chain oxidations and the products of liquid-phase cyclohexane oxidation. Discussions focus on the applicability of the stationary state method to liquid-phase oxidation reactions; mechanism of liquid hydrocarbon chain oxidation; kinetic equations for product accumulation in degenerate branching chain reactions; and changes of the volume of the liquid phase due to oxidation product formation. The text then ponders on experimental apparatus for the study of the liquid-phase oxidation of cyclohexane, including prevention of cyclohexane losses in the waste gases, explosion danger and problems of safety, and characteristics of gas sampling in cyclohexane oxidation apparatus. The manuscript takes a look at the kinetics of uncatalyzed cyclohexane oxidation and kinetics of cyclohexane oxidation in continuous flow systems. Topics include effect of temperature on the relative yield of cyclohexane oxidation products; kinetics of cyclohexane oxidation in a glass reactor; rate of oxygen absorption and accumulation of reaction products; ideal displacement reactor; and determination of diffusion factor. The publication is a dependable reference for readers interested in the oxidation of cyclohexane.

Book Description

The first book to place recent academic developments within the context of real life industrial applications, this is a timely overview of the field of aerobic oxidation reactions in the liquid phase that also illuminates the key challenges that lie ahead. As such, it covers both homogeneous as well as heterogeneous chemocatalysis and biocatalysis, along with examples taken from various industries: bulk chemicals and monomers, specialty chemicals, flavors and fragrances, vitamins, and pharmaceuticals. One chapter is devoted to reactor concepts and engineering aspects of these methods, while another deals with the relevance of aerobic oxidation catalysis for the conversion of renewable feedstock. With chapters written by a team of academic and industrial researchers, this is a valuable reference for synthetic and catalytic chemists at universities as well as those working in the pharmaceutical and fine chemical industries seeking a better understanding of these reactions and how to design large scale processes based on this technology.

Book Description

Cyclohexane oxidation is an industrially important reaction used as the first step in production of Nylon 6 and Nylon 6,6. Commercial technology employs a two stage process. The first stage of cyclohexane oxidation is very inefficient with 4-8% conversion of cyclohexane with 80% selectivity to cyclohexanol and cyclohexanone as desired products. According to some previously published work, using pure oxygen as an oxidant instead of conventionally used air, decreases the time needed to achieve 4% cyclohexane conversion; thus, increasing volumetric productivity at reported increased selectivity. The focus of this work was to systematically examine the effect of increased availability of oxygen on the rates and the selectivity of cyclohexane oxidation. It was concluded from the experimental and the modeling results that increased oxygen availability improves the productivity of cyclohexane oxidation at the fixed cyclohexane conversion (4%) as the residence time required achieving such conversion declines with the increase in oxygen concentration. A novel capillary reactor has been designed and tested for cyclohexane oxidation as a safer and more efficient way for hydrocarbon oxidation with oxygen or oxygen enriched air. The discrepancy between the experimental and modeling results was attributed to lower than expected gas-liquid mass transfer in the capillary Thus, it was concluded that the gas liquid reactions of this nature can be performed in the small diameter capillary reactor but the gas-liquid mixing has to be resolved in a better fashion and mass transfer improved.

Book Description

Hydrogen peroxide is a chemical that is becoming increasingly fashionable as an oxidant, both in industry and in academia and whose production is expected to increase significantly in the next few years. This growth in interest is largely due to environmental considerations related to the clean nature of hydrogen peroxide as an oxidant, its by-product being only water. To date this chemical has largely been employed as a non-selective oxidant in operations like the bleaching of paper, cellulose and textiles, or in the formulation of detergents, and only to a minimal extent in the manufacture of organic chemicals. This book has been organized to cover the different aspects of the chemistry of hydrogen peroxide. The various chapters into which the book is divided have been written critically by the authors with the general aim of stimulating new ideas and emphasizing those aspects that are likely to lead to new developments in organic synthesis in the coming future.

Book Description

This book offers a comprehensive overview of the most recent developments in both total oxidation and combustion and also in selective oxidation. For each topic, fundamental aspects are paralleled with industrial applications. The book covers oxidation catalysis, one of the major areas of industrial chemistry, outlining recent achievements, current challenges and future opportunities. One distinguishing feature of the book is the selection of arguments which are emblematic of current trends in the chemical industry, such as miniaturization, use of alternative, greener oxidants, and innovative systems for pollutant abatement. Topics outlined are described in terms of both catalyst and reaction chemistry, and also reactor and process technology.

Book Description

This monograph consists of the proceedings of the Fifth International Symposium on the Activation of Dioxygen and Homogeneous Catalytic Oxidation, held in College Station, Texas, March 14-19, 1993. It contains an introductory chapter authored by Professors D. H. R. Barton and D. T. Sawyer, and twenty-nine chapters describing presentations by the plenary lecturers and invited speakers. One of the invited speakers, who could not submit a manuscript for reasons beyond his control, is represented by an abstract of his lecture. Also included are abstracts of forty-seven posters contributed by participants in the symposium. Readers who may wish to know more about the subjects presented in abstract form are invited to communicate directly with the authors of the abstracts. This is the fifth international symposium that has been held on this subject. The first was hosted by the CNRS, May 21-29, 1979, in Bendor, France (on the Island of Bandol). The second meeting was organized as a NATO workshop in Padova, Italy, June 24-27, 1984. This was followed by a meeting in Tsukuba, Japan, July 12-16, 1987. The fourth symposium was held at Balatonfured, Hungary, September 10-14, 1990. The sixth meeting is scheduled to take place in Delft, The Netherlands (late Spring, 1996); the organizer and host will be Professor R. A. Sheldon.
