Book Description
The Proton: Applications to Organic Chemistry deals with several aspects of the proton drawn from organic chemistry. This book begins with an introductory chapter, followed by discussions on the strengths of neutral organic acids and neutral organic bases. The mode of transfer of hydrogen in its three forms—H+, H•, and H-, alternative sites of protonation or deprotonation of organic compounds, and acid-base chemistry of unstable and metastable species are also elaborated. This text concludes with a presentation of the activation induced in organic molecules by proton addition or removal and its catalytic effects. This publication is intended for practicing organic chemists and researchers conducting work on protons.

Acids and Bases
Author: Brian G. Cox
Publisher: OUP Oxford
ISBN: 0191649341
Category : Science
Languages : en
Pages : 283
Book Description
Acids and bases are ubiquitous in chemistry. Our understanding of them, however, is dominated by their behaviour in water. Transfer to non-aqueous solvents leads to profound changes in acid-base strengths and to the rates and equilibria of many processes: for example, synthetic reactions involving acids, bases and nucleophiles; isolation of pharmaceutical actives through salt formation; formation of zwitter- ions in amino acids; and chromatographic separation of substrates. This book seeks to enhance our understanding of acids and bases by reviewing and analysing their behaviour in non-aqueous solvents. The behaviour is related where possible to that in water, but correlations and contrasts between solvents are also presented. Fundamental background material is provided in the initial chapters: quantitative aspects of acid-base equilibria, including definitions and relationships between solution pH and species distribution; the influence of molecular structure on acid strengths; and acidity in aqueous solution. Solvent properties are reviewed, along with the magnitude of the interaction energies of solvent molecules with (especially) ions; the ability of solvents to participate in hydrogen bonding and to accept or donate electron pairs is seen to be crucial. Experimental methods for determining dissociation constants are described in detail. In the remaining chapters, dissociation constants of a wide range of acids in three distinct classes of solvents are discussed: protic solvents, such as alcohols, which are strong hydrogen-bond donors; basic, polar aprotic solvents, such as dimethylformamide; and low-basicity and low polarity solvents, such as acetonitrile and tetrahydrofuran. Dissociation constants of individual acids vary over more than 20 orders of magnitude among the solvents, and there is a strong differentiation between the response of neutral and charged acids to solvent change. Ion-pairing and hydrogen-bonding equilibria, such as between phenol and phenoxide ions, play an increasingly important role as the solvent polarity decreases, and their influence on acid-base equilibria and salt formation is described.

The Proton in Chemistry
Author: R.P. Bell
Publisher: Springer Science & Business Media
ISBN: 1475715927
Category : Science
Languages : en
Pages : 316
Book Description
The first edition of this book was based on the lectures which I gave at Cornell University during 1958 as George Fisher Baker Lecturer, and I would like to repeat my warmest thanks to Professor F. A. Long and the other members of the Department of Chemistry for their kindness and helpful advice. The present edition was largely written during the tenure of a Visiting Professorship awarded by the Royal Society and the Israeli Academy of Sciences. I am deeply indebted to both of these bodies and also to the hospitality of the Weizmann Institute of Science, in particular to Professor David Samuel and Professor F. S. Klein of the Isotopes Research Department. The subject as a whole has expanded greatly since 1959, especially in two fields, namely, the direct study of fast proton-transfer reactions (notably by the relaxation methods pioneered by Eigen), and the experi mental and theoretical study of hydrogen isotope effects. In order to keep the size of the book within reasonable bounds it has been necessary to adopt a selective policy, and this is particularly the case in Chapter 9 where I have chosen to treat a few types of reaction in some detail rather than to attempt a more complete coverage.

Proton Transfer Reaction Mass Spectrometry
Author: Andrew M. Ellis
Publisher: John Wiley & Sons
ISBN: 1118683579
Category : Science
Languages : en
Pages : 361
Book Description
Proton Transfer Reaction Mass Spectrometry (PTR-MS) is a rapidly growing analytical technique for detecting and identifying very small quantities of chemical compounds in air. It has seen widespread use in atmospheric monitoring and food science and shows increasing promise in applications such as industrial process monitoring, medical science and in crime and security scenarios. Written by leading researchers, this is the first book devoted to PTR-MS and it provides a comprehensive account of the basic principles, the experimental technique and various applications, thus making this book essential reading for researchers, technicians, postgraduate students and professionals in industry. The book contains nine chapters and is divided into two parts. The first part describes the underlying principles of the PTR-MS technique, including • the relevant ion-molecule chemistry • thermodynamics and reaction kinetics • a discussion of ion sources, drift tubes and mass spectrometers • practical aspects of PTR-MS, including calibration. The second part of the book turns its attention to some of the many applications of PTR-MS, demonstrating the scope and benefits, as well as the limitations, of the technique. The chapters that make up the second part of the book build upon the material presented in the first part and are essentially self-contained reviews focusing on the following topics: • environmental science • food science • medicine • homeland security, and • applications of PTR-MS in liquid analysis.
