    • F. Asinger
    • Inglés
    Mono-Olefins: Chemistry and Technology is a translation from the German and deals with the study of olefins from low ethylene to hexenes and olefins from the high hexenes to eicosenes. The book describes the gaseous or low-boiling olefins and the higher, normally liquid olefins (which have only a minor role in applications in the chemical industry). The olefins are considered important as they are added in the distillation of off-gases in refineries. Although the liquid olefins are used sparingly, these are needed to manufacture lubricants, synthetic detergents, and the higher aliphatic alcohols. 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. This book is beneficial to industrial chemists, researchers, technical designers, and engineers whose works are related with oil refinery and fossil fuels.

    • R. J. Schnitzer + 1 más
    • Inglés
    Experimental Chemotherapy, Volume I, attempts to condense the existing knowledge in the broad field of experimental chemotherapy in a comprehensive form. The arrangement of the subject matter follows a plan by which the not always avoidable repetitive description is reduced to a minimum. In most of the protozoan and metazoan infections it appeared advantageous to discuss the different series of active compounds according to the specific diseases and their causative agents. In other cases, owing to the wide range of activity of certain antibacterials, the material is arranged according to the groups of compounds. This first volume deals with infections caused by parasites, both protozoan and metazoan; it also contains general chapters on history of chemotherapy, toxicology, statistics, and drug resistance. It is hoped that the treatise will be useful to experimental workers engaged in the search for new chemotherapeutic remedies and in the study of their mechanism of action; to all who are involved in the teaching of pharmacology and therapeutics; and to physicians and veterinarians interested in the experimental basis of the drugs they are using.

    • Inglés
    VIIth International Symposium on Carbohydrate Chemistry is a collection of papers discussing thio sugars, pathways of synthesis for specific polysaccharides, and the structural chemistry of plant glycuronoglycans. Other papers explain ion binding on polyuronates as alginate and pectin, the effects of acetate substituents on the conformations of di- and polysaccharides, as well as the immunochemical approaches to the structural chemistry of polysaccharides. One paper investigates the stereochemical assignment in some 2-thio sugar derivatives and the stereochemical lability of 2-thioaldoses in basic media. Another paper examines the synthetic chemistry of oligosaccharides, particularly, the synthesis of trisaccharides, one of which is a repeating unit of O-antigenic polysaccharide from Salmonella anatum. One paper notes that plant acidic polysaccharides should be classified in terms of their basal core structures to enable groupings and comparisons of glycuronoglycans isolated from various sources. Another paper shows that the structure of the carbohydrate moiety of glycoproteins points to the biological role of carbohydrate moieties as possible cell recognition signals. This collection can prove valuable for bio-chemists, cellular biologists, micro-biologists, and developmental biologists.

    Lactation: A Comprehensive Treatise, Volume IV, The Mammary Gland/Human Lactation/Milk Synthesis, forms the fourth in a series. When the first three volumes were published in 1974, publication of future volumes was not contemplated. However, the gratifying acceptance by the scientific community and the continuation of rapid advances in lactation, have provided the impetus for the continuation of the series. The present volume is concerned with general aspects of the mammary gland, human lactation, and mechanisms of milk synthesis. The volume is divided into three main parts. Part I covers some aspects of the mammary gland and lactation not discussed in the first three volumes and expands on others. Topics discussed include the development of the mammary apparatus and neuroendocrine control of lactation. Part II is devoted to more specific consideration of human lactation as a whole. It includes studies on breast feeding and the breast cancer process. Part III on milk synthesis deals with the mechanisms of milk synthesis; enzymology and control of lactose biosynthesis; molecular aspects of milk protein biosynthesis; and ion and water transport in the mammary gland.

    • Inglés
    Annual Reports in Organic Synthesis—1979 presents an annual review of synthetically useful information that would prove beneficial to nearly all organic chemists, both specialist and nonspecialist in synthesis. It should help relieve some of the information storage burden of the specialist and should aid the nonspecialist who is seeking help with a specific problem to become rapidly aware of recent synthetic advances. In producing this volume the editors abstracted 46 primary chemistry journals, selecting useful synthetic advances. All reactions and methods which are new, synthetically useful, and reasonably general are included. Each entry is comprised primarily of structures accompanied by very few comments. The purpose of this is to aid the reader in rapidly scanning the book. Chapters I-III are organized by reaction type and constitute the major part of the book. Chapter IV deals with methods of synthesizing heterocyclic systems. Chapter V covers the use of new protecting groups. Chapter VI is divided into three main parts and covers those synthetically useful transformations that do not fit easily into the first three chapters. The first part deals only with functional group synthesis. The second part covers ring expansion and contraction, and the third part involves useful multistep sequences.

    Cyclophanes, Volume II, provides a comprehensive review of the field of cyclophane chemistry for the period between the earlier volume in this series (Bridged Aromatic Compounds by A. H. Smith, 1964) and the present (generally through 1981). An attempt has been made to provide a selection of topics that delineate the past and present of cyclophane chemistry and point toward some of its future directions. The ordering of chapters has been chosen to present background, theory, structure, and spectroscopy followed by a somewhat arbitrary division of cyclophanes into subgroups, roughly in order of increasing structural complexity. Key topics discussed include the synthesis and properties of heterophanes, condensed benzenoid and nonbenzenoid cyclophanes, multibridged and multilayered cyclophanes, cyclophanes in host-guest chemistry, and cyclophanes as synthetic analogs of enzymes and receptors. Individual chapters have been written so that they may be read with little or no direct reference to other chapters. Each stands alone as a review of a particular area of cyclophane chemistry and therefore some overlap between chapters will be apparent.

    • Inglés
    The Effect of Molecular Orientation on the Mechanical Properties of Polystyrene presents the results of a study that investigated the effect of molecular orientation on the mechanical properties of polystyrene. Oriented sheets of two commercial homopolystyrenes (PSA and PSB) differing in molecular weight, rheological and glass transition temperature properties were prepared by sheet extrusion and drawing. The properties of the resulting sheets were examined at seven different laboratories in Europe. The study focused on length reversion ratio, birefringence, orientation stress, shrinkage stress, and various mechanical properties such as rupture stress and strain, the specific energy of rupture, and sonic modulus and relaxation modulus. Impact behavior and environmental stress cracking behavior were also evaluated. One of the findings was that oriented polymers subjected to lateral strains can develop catastrophic crack growth when immersed in an active liquid. The onset of the cracks depends on the lateral strain imposed as well as the degree of orientation. PSB was more resistant than PSA. This monograph should be a useful resource for chemists.
