Book Description
Cyclobutadiene and Related Compounds describes the four-membered carbocyclic compounds that have only trigonally hybridized carbon atoms in the ring. The book discusses the chemistry of cyclobutadiene and the substituted cyclobutadienes, including the preparation of cyclobutadiene-metal complexes that can be done in four ways. These are (1) by reaction of acetylenes with transition metal compounds, (2) from cyclobutenyl metal complexes, (3) by transformation of other cyclobutadiene-metal complexes, and (4) by trapping cyclobutadienes with transitional metal compounds. The text also describes cyclobutadiene dianion, the chemistry of the cyclobutadienequinones, the condensed methylenecyclobutene aromatic systems, and the higher aromatic analogs of benzocyclobutadiene. The book cites proofs of the structure of biphenylene using chemical and physical methods. The text also presents theoretical aspects of the cyclobutadiene problem including studies regarding the ?-electronic state of cyclobutadiene; the comparisons of some of these studies; the framework energies and Janh-Teller considerations; and the substituted cyclobutadienes, cyclobutadiene divalent ions, and metal complexes. This book is suitable for scientists and researchers working in the field of organic chemistry, analytical chemistry, and molecular physics.

Book Description
1 3-Butadiene is a product of incomplete combustion resulting from natural processes and human activity. It is also an industrial chemical used primarily in the production of polymers. It enters the environment from exhaust emissions from gasoline and diesel-powered vehicles, from non-transportation fuel combustion, from biomass combustion and from industrial on-site uses. The highest atmospheric concentrations have been measured in air in cities and close to industrial sources. In this volume the risks to human health and the environment of this chemical are assessed. The general population is exposed to 1 3-Butadiene primarily through ambient and indoor air. Tobacco smoke may contribute significant amounts of 1 3-Butadiene. The available epidemiological and toxicological data provide evidence that 1 3-Butadiene is carcinogenic in humans and may also be genotoxic in humans.

Book Description
In Molecules, bestselling author Theodore Gray demonstrates, through stunning, never-before-seen images and illustrations, how the elements of the periodic table combine to form the molecules that make up our world. Everything physical is made up of the elements and the infinite variety of molecules they form when they combine with each other. In Molecules, Theodore Gray takes the next step in the story that began with the periodic table in his best-selling book, The Elements: A Visual Exploration of Every Known Atom in the Universe. Here, he explores, through fascinating stories and trademark stunning photography, the most interesting, essential, useful, and beautiful of the millions of chemical structures that make up every material in the world. Gray begins with an explanation of how atoms bond to form molecules and compounds, as well as the difference between organic and inorganic chemistry. He then goes on to explore the vast array of materials molecules can create, including: soaps and solvents; goops and oils; rocks and ores; ropes and fibers; painkillers and dangerous drugs; sweeteners; perfumes and stink bombs; colors and pigments; and controversial compounds including asbestos, CFCs, and thimerosal. Big, gorgeous photographs, as well as diagrams of the compounds and their chemical bonds, rendered with never before seen beauty, fill the pages and capture molecules in their various states. As he did in The Elements, Gray shows us molecules as we've never seen them before. It's the perfect book for his loyal fans who've been eager for more and for anyone fascinated with the mysteries of the material world.

Book Description
This volume, the fourth in a series which began in 1979, covers a greater variety of subjects than any previous single volume. The basis of selection has been topical interest; hence the tailor-making of polymers to develop specific properties, methods of improving com pound processability and the use of rubbers in the oil industry are featured alongside a discussion of safety aspects. We have again sought the cooperation of the foremost authorities on the chosen subjects and have been delighted at the response which has yielded a list of authors of international repute. A. w. K.
