Butadiene Production from Butenes - Cost Analysis - Butadiene E21A


Book Description

This report presents a cost analysis of 1,3-Butadiene (BD) production from mixed butenes using an oxidative dehydrogenation process. The process examined is similar to TPC/UOP Oxo-D process. In this process, butenes are catalytically dehydrogenated to produce a crude butadiene stream which is further purified to the final Butadiene product. In the purification step, raffinate is obtained as by-product.

Polychloroprene Production - Cost Analysis - CR E21A


Book Description

This report presents a cost analysis of Chloroprene Rubber (also known as Polychloroprene) production from butadiene and chlorine. 'The process examined is a typical vapor phase butadiene chlorination process, followed by a typical emulsion polymerization process. In this process butadiene is first chlorinated producing two chlorinated isomers, 1,4-dichloro 2-butene and 3,4-dichloro 1-butene. In a second step, 1,4-isomers are isomerized to 3,4-dichloro 1-butene. This chemical is then dehydrochlorinated in the presence of caustic soda producing chloroprene and sodium chloride. Finally, chloroprene is polymerized to form Polychloroprene. This report was developed based essentially on the following reference(s): (1) "Chloroprene", Kirk-Othmer Encyclopedia of Chemical Technology, 5th edition (2) "Polychloroprene", Kirk-Othmer Encyclopedia of Chemical Technology, 5th edition Keywords: Dupont, Chloroprene Rubber, Neoprene, Chlorination, Neoprene, Chloroprene Rubber, 2-Chlorobuta-1,3-Diene, Synthetic Rubbers




Clay-Polymer Nanocomposites


Book Description

Clay–Polymer Nanocomposites is a complete summary of the existing knowledge on this topic, from the basic concepts of synthesis and design to their applications in timely topics such as high-performance composites, environment, and energy issues. This book covers many aspects of synthesis such as in- situ polymerization within the interlamellar spacing of the clays or by reaction of pristine or pre-modified clays with reactive polymers and prepolymers. Indeed, nanocomposites can be prepared at industrial scale by melt mixing. Regardless the synthesis method, much is said in this book about the importance of theclay pre-modification step, which is demonstrated to be effective, on many occasions, in obtaining exfoliated nanocomposites. Clay–Polymer Nanocomposites reports the background to numerous characterization methods including solid state NMR, neutron scattering, diffraction and vibrational techniques as well as surface analytical methods, namely XPS, inverse gas chromatography and nitrogen adsorption to probe surface composition, wetting and textural/structural properties. Although not described in dedicated chapters, numerous X-ray diffraction patterns of clay–polymer nanocomposites and reference materials are displayed to account for the effects of intercalation and exfoliations of layered aluminosilicates. Finally, multiscale molecular simulation protocols are presenting for predicting morphologies and properties of nanostructured polymer systems with industrial relevance. As far as applications are concerned, Clay–Polymer Nanocomposites examines structural composites such as clay–epoxy and clay–biopolymers, the use of clay–polymer nanocomposites as reactive nanocomposite fillers, catalytic clay-(conductive) polymers and similar nanocomposites for the uptake of hazardous compounds or for controlled drug release, antibacterial applications, energy storage, and more. - The most comprehensive coverage of the state of the art in clay–polymer nanocomposites, from synthesis and design to opportunities and applications - Covers the various methods of characterization of clay–polymer nanocomposites - including spectroscopy, thermal analyses, and X-ray diffraction - Includes a discussion of a range of application areas, including biomedicine, energy storage, biofouling resistance, and more

Polymer Physics


Book Description

This book is the result of my teaching efforts during the last ten years at the Royal Institute of Technology. The purpose is to present the subject of polymer physics for undergraduate and graduate students, to focus the fundamental aspects of the subject and to show the link between experiments and theory. The intention is not to present a compilation of the currently available literature on the subject. Very few reference citations have thus been made. Each chapter has essentially the same structure: starling with an introduction, continuing with the actual subject, summarizing the chapter in 30D-500 words, and finally presenting problems and a list of relevant references for the reader. The solutions to the problems presented in Chapters 1-12 are given in Chapter 13. The theme of the book is essentially polymer science, with the exclusion of that part dealing directly with chemical reactions. The fundamentals in polymer science, including some basic polymer chemistry, are presented as an introduction in the first chapter. The next eight chapters deal with different phenomena (processes) and states of polymers. The last three chapters were written with the intention of making the reader think practically about polymer physics. How can a certain type of problem be solved? What kinds of experiment should be conducted? This book would never have been written without the help of my friend and adviser, Dr Anthony Bristow, who has spent many hours reading through the manuscript. criticizing the content.

Algae Based Polymers, Blends, and Composites


Book Description

Algae Based Polymers, Blends, and Composites: Chemistry, Biotechnology and Material Sciences offers considerable detail on the origin of algae, extraction of useful metabolites and major compounds from algal bio-mass, and the production and future prospects of sustainable polymers derived from algae, blends of algae, and algae based composites. Characterization methods and processing techniques for algae-based polymers and composites are discussed in detail, enabling researchers to apply the latest techniques to their own work. The conversion of bio-mass into high value chemicals, energy, and materials has ample financial and ecological importance, particularly in the era of declining petroleum reserves and global warming. Algae are an important source of biomass since they flourish rapidly and can be cultivated almost everywhere. At present the majority of naturally produced algal biomass is an unused resource and normally is left to decompose. Similarly, the use of this enormous underexploited biomass is mainly limited to food consumption and as bio-fertilizer. However, there is an opportunity here for materials scientists to explore its potential as a feedstock for the production of sustainable materials. - Provides detailed information on the extraction of useful compounds from algal biomass - Highlights the development of a range of polymers, blends, and composites - Includes coverage of characterization and processing techniques, enabling research scientists and engineers to apply the information to their own research and development - Discusses potential applications and future prospects of algae-based biopolymers, giving the latest insight into the future of these sustainable materials
