The book then explains the three processes used to separate olefin containing mixtures of gases into fractions by the C-number or to convert olefins in the pure state: distillation, absorption, and adsorption. The author then describes the processes in manufacturing carburetor fuel from petroleum and natural gases. Petroleum oil is a mixture of paraffinic, naphthenic, and aromatic hydrocarbons and has no olefins. The text describes the complete process of refining petroleum into different products such as gasoline, kerosene, lubricants, and spotting benzenes. Then the book explains the polymerization of olefins to produce carburetor fuels either by the thermal method or catalytic method. The text notes some research made into double-bond isomerization in mono-olefins and their possible applications.

    Model Answers in Organic Chemistry aims to provide the student (particularly the student who is working on his own or who is inexperienced in sitting for examinations) with a series of answers which show what is required and expected in the General Certificate of Education Advanced Level and Ordinary National Certificate examinations. Opinions differ in many cases as to what is required in answer to a given question, and the authors would not suggest that their answers are perfect. Nor should the student use them as such, or assume that all the organic chemistry he needs is to be found in this book. The answers are intended only to supplement the information in the normal textbook used in preparing for the examination, and to serve as a guide to the reader, in that they show, for example, how long an answer should be, how information should be presented, the type of sketch required, the essential equations and details of a preparation. The book presents questions on the following topics: structure and isomerism, alkyl halides and related compounds, ether and alcohols, alcohols and phenols, aldehydes and ketones, carboxylic acids, esters, nitriles (cyanides), amines, diazonium compounds, and benzene and derivatives.

    Organic Chemistry: The Name Game: Modern Coined Terms and their Origins is a lighthearted take on the usually difficult and systematic nomenclature found in organic chemistry. However, despite the lightheartedness, the book does not lose its purpose, which is to serve as a source of information on this particular subject of organic chemistry. The book, arranged into themes, discusses some organic compounds and how they are named based on their structure, makeup, and components. The text also explains the use of Greek and Latin prefixes in nomenclature and many other principles in nomenclature. The book also includes an appendix that contains very useful information on nomenclature, such as the etymology of certain element and chemical names, numerical prefixes, and the Greek alphabet. The text is not only for students who wish to be familiarized with a different style of organic chemistry nomenclature, but also for professors who aim to give students an enjoyable yet memorable learning experience.

    Coordination Chemistry XVI is a compendium of papers that deals with structured absorption band, intra-molecular electron transfer, and the influence of natural and synthetic ligands on the transport and function of metal ions in the environment. Experiments show that the chemical, spectral and kinetic results of the physical state of an enzyme can be a significant experimental variable that will change function-related-con... Another paper points out the dangers of assigning weakly structured bands to partially resolved vibrations, to lower symmetry, to spin-orbit coupling, and to the Jahn-Teller effects. One paper deals with intra-molecular electron transfer in three manifestations: 1) in traditional oxidation-reduction reactions; 2) in induced electron transfer; and 3) in mixed valence complexes. Another paper discusses the reactivity of polynuclear metal complexes involving metal-metal bonds with simple inorganic and organic molecules, particularly, polynuclear aggregates' basic structural forms and polynuclear's fluxional nature. One paper investigates the environmental effects of coordination compounds that disturb the natural balance and levels of metal ions and metal complexes in the ecosystem. The paper cites examples of pollutions caused by abnormal amounts of metal salts and metal complexes introduced in the ecosystem, and the presence of synthetic ligands or abnormal levels of natural ligands in the environment. The compendium is suitable for analytical and organic chemists, chemical engineers, environmentalists, and students of biochemistry.

    Oxidases and Related Redox Systems is a collection of papers from the Third International Symposium on Oxidases and Related Reduction Systems held in Albany, New York on July 3-7, 1979. This book deals with the oxygen and peroxide activating enzymes field. The book addresses electron transfer related to oxygen biochemistry by comparing quantum, semiclassical, and classical methods of electron transfer reactions. Several papers then discuss the active and toxic states of oxygen and superoxide as the discovery of superoxide dismutase activity of erythrocuprein can provide a means to studying oxygen reaction in biological systems. One paper then compares the active sites of molluskan and arthropodan hemocyanins, which are known as reversible oxygen-carriers. The result of this study is presented in a table. Other papers discuss the flavin catalyzed reactions of molecular oxygen and the implications of the physiological function of D-amino acid oxidase from inhibition studies. The book then explains the role of carbon monoxide in the reaction mechanism of oxygen with cytochrome oxidase. This collection will prove beneficial for research students and professors in the field of biochemistry and chemical physics.
