Download or read book Polyoxymethylene Production Process Cost Analysis POM E11A written by Intratec and published by Intratec. This book was released on 2019-09-17 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a cost analysis of Polyacetal Resins (also known as Polyoxymethylene, POM) production from acetic anhydride and formaldehyde. The process examined is similar to the one owned by DuPont. In this process, starting formaldehyde (37wt% solution) is concentrated to a purity higher than 99.9wt% by means of two distillation steps and a treatment step. High purity formaldehyde is then polymerized in an inert cyclohexane medium. This report was developed based essentially on the following reference(s): (1) "Acetal Resins", Kirk-Othmer Encyclopedia of Chemical Technology, 5th edition (2) US Patent 2768994, issued to Du Pont in 1956 Keywords: Acetyl resin, polyoxymethylene (POM) resins, polymer of formaldehyde, DuPont, polyformaldehyde

This book was released on 2017-06-01 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a cost analysis of Polyacetal Resins (also known as Polyoxymethylene, POM) production starting from methanol and acetic anhydride The process examined is a conventional silver-catalyzed process with methanol recycle, combined with one owned by DuPont for producing the POM. In this process, methanol is converted to Formaldehyde (37wt% solution) over a silver catalyst. The formaldehyde (37wt% solution) is concentrated to a purity higher than 99.9wt% by means of two distillation steps and a treatment step. High purity formaldehyde is then polymerized in an inert cyclohexane medium.

This book was released on 2019-09-17 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a cost analysis of Polyethylene Terephthalate (PET) production from ethylene glycol and purified terephthalic acid (PTA). The process examined is a typical melt-phase polymerization followed by solid-state polymerization. In this process, initially an oligomer intermediate is produced by the esterification of PTA with ethylene glycol. The oligomer then undergoes a melt-polymerization and a solid-state polymerization, leading to a bottle grade PET.

Download or read book Comets II written by M. Festou and published by University of Arizona Press. This book was released on 2004-11 with total page 780 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of comets is a field that has seen tremendous advances in recent years, far surpassing the knowledge reflected in the original Comets volume published as part of the Space Science Series in 1982. This new volume, with more than seventy contributing authors, represents the first complete overview of comet science in more than a decade and contains the most extensive collection of knowledge yet assembled in the field. Comets II situates comet science in the global context of astrophysics for the first time by beginning with a series of chapters that describe the connection between stars and planets. It continues with a presentation of the formation and evolution of planetary systems, enabling the reader to clearly see the key role played in our own solar system by the icy planetesimals that were the seeds of the giant planets and transneptunian objects. The book presents the key results obtained during the 1990s, in particular those collected during the apparition of the exceptional comets C/Hyakutake and C/Hale-Bopp in 1996-1997. The latest results obtained from the in situ exploration of comets P/Borrelly and P/Wild 2 are also discussed in detail. Each topic of is designed to be accessible to students or young researchers looking for basic, yet detailed, complete and accurate, information on comet science. With its emphasis on the origin of theories and the future of research, Comets II will enable scientists to make connections across disciplinary boundaries and will set the stage for discovery and new understanding in the coming years.
Download or read book Polymer Physics written by U.W. Gedde and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
