Dieses kompakte Einführungslehrbuch vermittelt die wesentlichen Grundlagen der Technischen Chemie. Es richtet sich in erster Linie an Studierende der Chemie sowie des Chemie- und des Bioingenieurwesens und setzt lediglich Grundkenntnisse in Organischer, Anorganischer und Physikalischer Chemie voraus. Der Stoff ist in vier Teile gegliedert:

  • I. Grundlagen: Der Weg von der Laborchemie über den Technikums- bis zum Produktionsmaßstab ― Prozessverbund der chemischen Industrie ― Produktstammbäume ― Physikalisch-chemische Grundlagen
  • II. Reaktions- und Trenntechnik: Der Reaktionsteil chemischer Prozesse ― Ideale und reale Reaktortypen ― Thermische und mechanische Grundoperationen ― Vorbereitung von Edukten ― Nachbereitung von Prozessströmen ― Chemische Fließschemata
  • III. Verfahrensentwicklung: Auswahl chemischer Verfahren für die industrielle Chemie ― Optimale Rohstoffe ― Umweltaspekte ― Heterogene Katalyse ― Homogene Katalyse ― Wirtschaftlichkeit
  • IV. Chemische Prozesse: Wichtigste Produktgruppen der industriellen Chemie ― Verarbeitung fossiler Rohstoffe ― Organische und anorganische foundation- und Zwischenchemikalien ― Endprodukte ― Polymere ― Organische Feinchemikalien ― Nachwachsende Rohstoffe

Jedes Kapitel ist kompakt aufgebaut und mit Abbildungen, Gleichungen, Fließschemata, Tabellen, Apparatezeichnungen und Fotos anschaulich gestaltet. Alle Kapitel enden mit einer kurzen Zusammenfassung, den "Take domestic Messages". Ergänzt wird jedes Kapitel durch zehn kurze Testfragen, die sich nach sorgfältigem Durcharbeiten des Textes schnell lösen lassen; die Antworten stehen am Ende des Buches. Zu allen Kapiteln findet guy Literaturangaben, die sich auf wesentliche Nachschlagewerke und Lehrbücher konzentrieren.

By James S. Ketchum

Chemical struggle watchers, from scientists to coverage advocates, usually ask yourself what went on on the military Chemical middle in the course of the 1960's. It was once a decade within which millions of military enlisted males served as volunteers for the secrets and techniques trying out of chemical brokers. the particular ancient checklist, even if, has beforehand remained disturbingly incomplete. What chemical compounds used to be the Arm learning? Why was once this system by no means absolutely documented in books to be had to the general public? Who deliberate and performed the assessments, and what was once their goal? How and through whom, have been the volunteers recruited? How safely have been they prompt ahead of giving their trained consent? What lengthy diversity results, if any, were present in follow-up reports? Written by means of the doctor who performed a pivotal function in psychoactive drug checking out of 1000's of volunteers, the tale breaks an professional silence that has lasted nearly fifty years. Dr. James Ketchum could be the purely scientist nonetheless equivalent to the duty. His booklet is going some distance towards revealing the contents of as soon as labeled files that also stay in limited records. the writer spent many of the decade trying out over a dozen capability incapacitating brokers together with LSD, BZ and marijuana derivatives. His 380-page narrative, loaded with either outdated and up to date photos, derives from the technical reviews, memoranda, motion pictures, notes and stories. Written essentially for the final reader yet supplemented by way of a voluminous appendix of graphs and tables for the technically vulnerable, Dr. Ketchum's e-book combines a subjective diary with an goal document of the exterior occasions that formed and at last terminated this system. casual and autobiographical standard, it contains various fun anecdotes and character pictures that make it at the same time fascinating and informative.

The aim of this quantity is to give the newest planetary stories of a global physique of scientists excited about the actual and chemical facets of terrestrial planets. lately planetary technological know-how has constructed in leaps and limits. it is a results of the applying of a wide variety of medical disciplines, fairly actual and chemical, to an figuring out of the data obtained from manned and unmanned area exploration. the 1st 5 chapters expound on a few of the prior and up to date observations in an try to boost significant physical-chemical versions of planetary formation and evolution. For any dialogue of the chemical strategies within the sunlight nebula, it is very important comprehend the boundary stipulations of the actual variables. In bankruptcy 1, Saf­ ranov and Vitjazev have laid down explicitly all of the actual constraints and the issues of time-dependence of nebular evolutionary tactics. Planetary scientists and scholars will locate during this bankruptcy a set of astrophysical parameters at the move of angular momentum, formation of the disk and the gasoline envelope, nebular turbulence, actual blending of debris of varied origins and development of planetesimals. The authors finish their paintings with very important info on ev­ olution of terrestrial planets. even if symbols are outlined within the textual content of the object, readers who're now not conversant in the various symbols and abbreviations in astrophysical literature will locate it precious to refer to the Appendix for causes.

Sulfonium compounds were recognized to the natural chemist for nearly ninety years. in the course of such a lot of this era they remained curiosities, well matched for didactic reasons to demonstrate yes similarities to ether adducts and to natural ammonium compounds. Their exploration remained principally within the educational realm, simply because no strange useful functions have been present in spite of a gradual raise within the recognition paid to them. An occasion that sometimes places a category of compounds into the heart of curiosity is the popularity of its prevalence in nature and of targeted organic value. the 1st traditional sulfonium compound was once chanced on lower than two decades in the past, slightly by accident instead of because the climax of a few coveted biochemical challenge. steadily, although, the original function of sulfonium compounds, specially of S-adenosyl­ methionine, in enzymatic staff move reactions akin to trans­ methylation used to be well-known, and the new upsurge of curiosity has been unheard of. the current overview is directed towards an interpretation of the houses and capabilities of organic sulfonium compounds with widespread connection with their structural chemistry. the information offered the following might recommend novel or more desirable analytical recommendations and new interpretations of the mechanism of workforce move. moreover, a stimulus can be derived for the layout of sulfonium compound analogues. the supply of aggressive analogues of biochemical key compounds has aided within the figuring out of the functionality of almost all metabolic intermediates, prosthetic teams of enzymes, supplementations, amino acids, and different compounds. The trend may be related in sulfonium biochemistry.

With a view to make additional development in elucidating the mechanism of NOS catalysis will probably be necessary to throw mild at the interplay among the enzyme and its substrate. An figuring out of the catalytic website also will support the advance of therapeutically vital NOS inhibitors. particularly. it is going to be worthy to discover any adjustments that exist among the substrate binding websites of the 3 NOS isozymes that may be exploited for the improvement of isoform selective NOS inhibitors. A comparability of NOS to different Arg-binding proteins has proven no major series homology (159). additionally, the inability of a 3D constitution and shortage of vital series homology among the NOS oxygenase area and identified cytochromes P450 has made it tough to spot residues and build a version of the distal heme pocket liable for substrate binding. even if, a few teams are presently practicing crystallisation of the separate NOS reductase and oxygenase domain names of the 3 isoforms for X-ray diffraction reviews; the 1st X-ray constitution is perhaps approaching inside of an issue of months. * the result of those stories are anticipated to unravel a few of the uncertainties surrounding the constitution of the NOS catalytic website. initial X-ray diffraction research of CPR from rat liver has already been stated by way of MASTERS et al. (524) and the long run emergence of an in depth constitution for this protein should still throw gentle at the constitution and serve as of the NOS reductase area.
