Book excerpt: Investigates the oxidation properties of titanium silicalite-1 (TS-1) catalyst for the oxidation of alcohols such as 2-propanol, 1-propanol, ethanol and methanol at concentration 5 vo1%. In addition the concentration of oxygen in the feed gas from 0-21 vo1% is studied to determine the effect of oxygen concentration on the conversion of alcohols and product selectivities. The catalytic test reaction was carried out with 0.1 gram of catalyst packed in a microreactor at temperature ranging from 100 to 500 C and atmospheric pressure. The research found that the TS-1 can play role as an effective catalyst for alcohol oxidation reactions in gas phase and the oxidation property of the TS-1 catalyst depends on reactant. For 1-propanol and 2-propanol, the oxidation rate is much higher than the dehydration rate. For ethanol, the oxidation rate is quite comparative to the dehydration rate. The oxidation reation, however, dominates the conversion of ethanol in low reaction temperature region (200-400 C). For methanol, the combustion reaction dominates the conversion.

This book was released on 2000 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: The oxidation property of the Co-Mg-O/TiO2 (8wt%Co, 1wt%Mg) catalyst was investigated by using the selective oxidation reaction of 1-propanol and 2-propanol as test reactions. It was found that the oxidation property of Co-Mg-O/TiO2 catalyst depended on type of the reactants. For the oxidation of 1-propanol, Co-Mg-O/TiO2 catalyst provided the maximum propionaldehyde yield ca. 57%. In case of 2-propanol oxidation reaction, it was found that Co-Mg-O/TiO2 catalyst was an active catalyst for selective oxidation reaction. The main product at low reaction temperature was propylene while at high reaction temperature the main reaction products were propylene and propionaldehyde. From the result of propylene oxidation, it indicated that propionaldehyde was produced directly from propylene. In addition, the sequence of cobalt and magnesium loading had no effect on the structure and catalytic performance of this catalyst, while the type of support affected the selectivity of supported cobalt catalyst.

The work reflects the diversity of the subject by including ongoing research spanning coordination chemistry, organometallic chemistry, bioinspired catalysis, proton and electron transfer, and the ability of such ligands to interact with early and late transition metals, lanthanides, and actinides. The book is divided into three parts, devoted to introduction and concepts, applications, and case studies. After the introduction on key concepts related to the field, and the different types of ligands and complexes in which ligand-centered redox activity is commonly observed, mechanistic and computational studies are described. The second part focuses on catalytic applications of redox-active complexes, including examples from radical transformations, coordination chemistry and organic synthesis. Finally, case studies of redox-active guanidine ligands, and of lanthanides and actinides are presented. Other specific sample topics covered include: An overview of the electronic features of redox-active ligands, covering their historical perspective and biological background The versatility and mode of action of redox-active ligands, which sets them apart from more classic and tunable ligands such as phosphines or N-heterocyclic carbenes Preparation and catalytic applications of complexes of stable N-aryl radicals Metal complexes with redox-active ligands in H+/e- transfer transformations By providing up-to-date information on important concepts and applications, Redox-Active Ligands is an essential reading for researchers working in organometallic and coordination chemistry, catalysis, organic synthesis, and (bio)inorganic chemistry, as well as newcomers to the field.
Download or read book Catalytic Aerobic Oxidations written by Esteban Mejía and published by Royal Society of Chemistry. This book was released on 2020-07-14 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxidation reactions are an important chemical transformation in both academia and industry. Among the major advances in the field has been the development of catalytic processes, which are not only selective and efficient, but also allow the replacement of common stoichiometric oxidants with molecular oxygen, ideally from air at atmospheric pressure. This results in processes with higher atom efficiency, where water is the only side product in line with the principles of green chemistry. Focusing on the use of molecular oxygen as the terminal oxidant, this book covers recent advances in both heterogeneous and homogeneous systems, with and without metals and on the “taming” of the highly reactive oxygen gas by use of micro-flow reactors and membranes. A useful reference for industrial and academic chemists working on oxidation processes, as well as green chemists.

Available in PDF, EPUB and Kindle. Book excerpt: Over the last few years, there has been a growing interest in the development of sustainable processes for large-scale production of commodities. As such, Alcohol Oxidation: Reaction, Effects and Applications addresses recent developments in metal-catalyzed selective oxidation reactions of alcohols to carbonyl-containing compounds under unconventional conditions. Following this, the authors examine how simple alcohols have been used as feedstocks for the preparation of a variety of enantioenriched substances. Cascade reactions allow for the elaboration of complex molecules from simple starting materials in a very efficient way. Several bonds can be made in one-pot procedures without the need for intermediates to be isolated. Metal-organic frameworks and covalent organic frameworks are two classes of highly porous materials that have been heavily investigated in recent years. As such, in this compilation the authors focus on the use of metal-organic frameworks as heterogeneous oxidation catalysts. Enantiopure alcohols are important starting materials and intermediates for the synthesis of many biologically active compounds and fine chemicals. The use of enzymes for the kinetic resolution of racemates has produced affordable enantiopure compounds in good yields, however non-enzymatic chiral catalytic systems have been gaining ground. Accordingly, the effective non-enzymatic oxidative kinetic resolutions of racemic alcohols and related compounds such as diols or benzoins are summarized and discussed. Lastly, the potential employment of the electrochemical process to oxidize alcohols in a more efficient way than the usual chemical method is presented. The use of the electrode potential as a controllable variable and driving force of the process allows for the oxidation of some alcohol molecules without of the very aggressive nature of reactants.

Book excerpt: The selective oxidation of alcohols is one of the most challenging reactions in green chemistry. While the current chemical industry uses organic and inorganic oxidants to produce carbonyl compounds, it is highly desirable to use a heterogeneous catalyst for the efficient oxidation of alcohols. The present research is focused on increasing the activity and selectivity towards the corresponding carbonyl of the heterogeneous oxidation for alcohols. The low activity of 5 wt.%Pt-1 wt. %Bi/Carbon for the oxidation of 2-octanol was investigated in a 500ml stirred tank reactor. The fast reaction rate drops dramatically from 0.23 M/hr to 0.006 M/hr after 15 minutes reaction time when heptane was used as solvent. Different possible causes such as overoxidation, leaching and poisoning were examined. It was found that the loss of high conversion rate was due to product adsorption and hence, different solvents were investigated. A mixture of 16-18% v/v dioxane in heptane was able to effectively regenerate active sites and allow a constant reaction rate of 0.07M/hr. The effects of temperature and pressure were also studied. Gas-liquid, liquid-solid and internal mass transfer effects were determined experimentally and semi-empirically. Six different Langmuir-Hinshelwood rate models were examined where a modified model based on Schuurman et al. (1992) was found to adequately describe the experimental data. The novel 2.5%Au-2.5%Pd/titania catalyst was investigated for the oxidation of benzyl alcohol. Different parameters such as catalyst oxidation state, pressure and stirrer design were studied to increase the activity and selectivity of the catalyst. The selectivity was shown to be highly dependent on the oxygen concentration. Therefore, the pressure, temperature, catalyst treatment were optimised and the reactor configuration was re-designed to enhance oxygen transport to the catalyst. While the conversion rate was unaffected by the oxygen concentration, the catalyst pre-treatmen.
