Download Verhalten und Abbau von Umweltchemikalien: by Walter Klöpffer PDF

By Walter Klöpffer

Um die Gefahrdung der Umwelt durch Chemikalien einschatzen zu konnen, reicht es nicht aus, nur die Schadwirkung, d. h. den Einfluss
der Chemikalie auf die Umwelt zu betrachten. Auch der Einfluss der Umwelt auf die Chemikalie spielt eine wichtige Rolle, uber deren
Verteilung, Verbreitung und Abbau in den verschiedenen Umweltkompartimenten. Seit etwa 30 Jahren existieren immer wieder verbesserte
Modelle, die diese Umweltfaktoren abbilden und eine Vorhersage zu Dauer und Intensitat der Umweltgefahrdung nach Freisetzung eines
Schadstoffes ermoglichen.

Mit Hilfe dieser Einfuhrung in die Grundlagen des Verhaltens von Chemikalien in der Umwelt wird der Leser in die Lage versetzt, die verfugbaren Rechenmodelle und Simulationen zum Abbau von Chemikalien in Luft, Wasser und Boden sinnvoll einzusetzen und deren Ergebnisse fachgerecht zu interpretieren.

Das Buch besteht aus vier Teilen. Der erste Teil dient als Einleitung in die Thematik, der zweite befasst sich mit der Verbreitung und Verteilung
von Chemikalien in Luft, Wasser und Boden. Im dritten Teil wird der abiotische und biotische Abbau der Chemikalien betrachtet. Im vierten Teil schlie?lich werden die verschiedenen Verteilungs- und Abbauwege zu einfachen bis komplexen Rechenmodellen zusammengefugt,
und die wichtigsten, von nationalen und internationalen Organisationen verwendeten Modelle werden eingehend anhand von Beispielen erlautert.

Download Heterogeneous Catalysis in Organic Chemistry by Gerard V. Smith,Ferenc Notheisz PDF

By Gerard V. Smith,Ferenc Notheisz

The good points of this booklet in order to be of targeted curiosity to educational natural chemists are the advent (Chapter 1), which offers a quick path at the suggestions and language of heterogeneous catalysis, covers natural response mechanisms of hydrogenation (Chapter 2), hydrogenolysis (Chapter 4), and oxidation (Chapter 6), a provides difficulties and suggestions particular for working heterogeneous catalytic natural reactions in answer. those fabrics can complement complex chemistry courses.

Most man made natural chemists use numerous "protecting teams" which they connect to useful teams (reactive teams of atoms) whereas a few response is being carried out on one other a part of the molecule. those maintaining teams hinder reactions of the sensible teams in the course of different reactions and are got rid of later by way of a heterogeneous catalytic procedure known as hydrogenolysis. One designated characteristic of this booklet, now not present in different books on catalysis, is an exhaustive bankruptcy (Chapter four) on hydrogenolysis, that's dredged from the hot artificial literature released via sleek natural chemists. educational natural chemists should still locate this bankruptcy super helpful and will desire to undertake the e-book as a complement for complex natural chemistry classes designed for seniors and for graduate scholars. it is going to even be necessary for professors and their learn teams engaged in man made natural chemistry.

Many educational natural chemists aren't conscious of contemporary advances in heterogeneous enantioselective catalysis (Chapter three) or in selective low temperature, liquid section heterogeneous catalytic oxidations via hydrogen peroxide (Chapter 6). those area of expertise themes are well timed and should be new to educational natural chemists and will be used to complement their complex courses.

Several beneficial properties of this booklet can also be of detailed curiosity to commercial chemists who're surprising with heterogeneous catalysis. Many strong natural chemists are rent by way of undefined. They synthesize a brand new compound utilizing usual natural man made strategies yet are proficient by way of their manager that they need to convert a few of their artificial steps into heterogeneous catalytic steps. they might not were uncovered to heterogeneous catalysis and feature few locations to show. This ebook deals them a crash path in heterogeneous catalysis in addition to many examples of reactions and stipulations with which they could begin their search.

Those business natural chemists already conversant in heterogeneous catalysis will locate this publication helpful as a connection with many examples within the contemporary literature. they'll locate fresh floor technological know-how discoveries correlated with heterogeneous catalysis or natural reactions and mechanistic feedback designed to stimulate leading edge nontraditional wondering natural reactions on surfaces.

  • Written by means of natural chemists for natural chemists
  • Introduces heterogeneous catalysis suggestions and language
  • Presents a finished compilation of shielding crew elimination procedures
  • Covers liquid-phase hydrogenations, hydrogenolysis, and oxidations
