Available in PDF, EPUB and Kindle. Book excerpt: The primary goal of this research was to find a renewable synthesis method for the production of propylene oxide. Significant quantities of glycerin are formed as a co-product when soybean oil is used to produce bio-diesel. This glycerin can be used to produce propylene glycol, which can undergo dehydration over basic catalysts to produce propylene oxide (PO), along with eight other products: acetaldehyde, propionaldehyde, acetone, 2-propanol, 1-propanol, allyl alcohol, acetol, and dipropylene glycol. A variety of catalysts were prepared for each set of reactions, and dehydration was carried out in a plug flow reactor. For this thesis, only three main catalysts are presented, such as Na/Al2O3 (sodium acetate on alumina), Cs-ETS-10, and Na acac/MgO (sodium acetyl acetonate on nanocrystalline MgO). Dehydration reactions were performed with different masses of catalyst, reactor temperatures, and residence times to optimize the selectivity to PO. The highest selectivity to PO was obtained as 12.33% for Na acac/MgO catalyst at 400_ C, 0.1g, and a N2 flow rate of 20SCCM. Even though Cs-ETS-10 catalyst was active for PO production, it also produced higher amounts of dipropylene glycol (80%). Dipropylene glycol appears to act as an active intermediate in the dehydration of propylene glycol to propylene oxide over Cs-ETS-10 catalyst, which would limit PO selectivity to 50%. The Na/Al2O3 resulted in low selectivity of 2% to PO, although it gave an appreciable selectivity of 60% to propionaldehyde. The reaction pathway to PO over these catalysts was also studied. Dehydration of propylene glycol to propylene oxide over Na/Al2O3, and Na acac/MgO catalysts appears to be a direct dehydration, rather than the involvement of a dipropylene glycol active intermediate.

Available in PDF, EPUB and Kindle. Book excerpt: Metal-Catalyzed Oxidations of Organic Compounds: Mechanistic Principles and Synthetic focuses on the oxidative transformations of functional groups. This book explores oxidation as being extensively used in the laboratory synthesis of fine organic chemicals and in the manufacture of large-volume petrochemicals. Organized into two parts encompassing 13 chapters, this book starts with an overview of the mechanistic principles of oxidation–reduction in biochemical, organic, and inorganic systems. This text then proceeds with a discussion of the use of molecular oxygen, hydrogen peroxide, and alkyl hydroperoxides as primary oxidants. Other chapters explore stoichiometric oxidations with metal oxidants, which include permanganate and chromic acid. This book discusses as well the synthetic applications of catalytic oxidations as well as the technology of petrochemical oxidation. The final chapter deals with the autoxidations of sulfur, phosphorus, and nitrogen compounds. This book is intended for chemists involved in organic synthesis, catalysis, and organometallic chemistry, both in academic institutions and in industrial laboratories.

This book was released on 2018-05-18 with total page 775 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of Americans use e-cigarettes. Despite their popularity, little is known about their health effects. Some suggest that e-cigarettes likely confer lower risk compared to combustible tobacco cigarettes, because they do not expose users to toxicants produced through combustion. Proponents of e-cigarette use also tout the potential benefits of e-cigarettes as devices that could help combustible tobacco cigarette smokers to quit and thereby reduce tobacco-related health risks. Others are concerned about the exposure to potentially toxic substances contained in e-cigarette emissions, especially in individuals who have never used tobacco products such as youth and young adults. Given their relatively recent introduction, there has been little time for a scientific body of evidence to develop on the health effects of e-cigarettes. Public Health Consequences of E-Cigarettes reviews and critically assesses the state of the emerging evidence about e-cigarettes and health. This report makes recommendations for the improvement of this research and highlights gaps that are a priority for future research.
