Substituent Effects in Organic Polarography by Petr Zuman Pdf

During the forty years which have passed since Masuzo Shikata published his paper on the reduction of nitrobenzene at a dropping mercury electrode, the number of polarographic studies of organic compounds in the literature has risen to several thousands. The ever increasing amount of experimental data was in need of some unified method of classification which would yield unambiguous and possibly complete information on the polarographic behavior of organic substances. Dr. Zuman's book presents an original attempt to meet this need by providing a system based on correlations between the polaro graphic half-wave potentials of organic depolarizers and their Hammett constants. I consider this a very happy conception, for, more than any other book yet written, it brings polarography nearer to the organic chemist; and it will undoubtedly convince him that, in its application to his subject, the method is more than a mere analytical tool. The author hardly needs any introduction. During many years of research in the field of organic polarography, he has published numerous papers on a variety of problems; his latest interest is the application of the Hammett-Taft equation to polarographic measure ments, in which he has done pioneering work. It remains for me to hope that this book, which opens up new prospects for the fruitful application of polarography, may inspire vii viii Foreword some reader with useful ideas in his search for new paths in his research problems.

Topics In Organic Polarography by P. Zuman Pdf

Even though the nwnber of requests for reprints and the number of quotations in the Science Citation Index has indicated an ever-increasing interest in topics of organic polarography, I have often felt that the reason that some work is less known may well be because the papers were published in less accessible journals. Therefore, I was pleased when I was asked to prepare a selection of my papers on organic polarography for reprinting. This collection of papers may indicate some of the possibilities offered by polarography in the study of properties of organic compounds. The fact that the papers are published in one volume, not only makes the information more easily accessible for the reader, but also enables a direct comparison of related topics. The mode of selection is discussed in the Introduction. The papers reprinted in this volume are mostly based on work carried out in the J. Heyrovsky Institute of Polarography of the Czechoslovak Academy of Sciences in Prague, in cooperation with my co-workers. I would like to take this opportunity of thanking all of them for the pleasure I got from this cooperation on the solution of varying problems of organic electrochemistry .

Comprehensive Treatise of Electrochemistry by Peter Horsman,Brian E. Conway,E. Yeager Pdf

It is now time for a comprehensive treatise to look at the whole field of electrochemistry. The present treatise was conceived in 1974, and the earliest invitations to authors for contributions were made in 1975. The completion of the early volumes has been delayed by various factors. There has been no attempt to make each article emphasize the most recent situation at the expense of an overall statement of the modern view. This treatise is not a collection of articles from Recent Advances in Electrochemistry or Modern Aspects of Electrochemistry. It is an attempt at making a mature statement about the present position in the vast area of what is best looked at as a new interdisciplinary field. Texas A & M University J. O'M. Bockris University of Ottawa B. E. Conway Case Western Reserve University Ernest Yeager Texas A & M University Ralph E. White Preface to Volume 8 Experimental methods in electrochemistry are becoming more diverse. This volume describes many of the new techniques that are being used as well as some of the well-established techniques. It begins with two chapters (1 and 2) on electronic instrumentation and methods for utilization of microcomputers for experimental data acquisition and reduction. Next, two chapters (3 and 4) on classical methods of electrochemical analysis are presented: ion selective electrodes and polarography.

Practical Polarography by J. Heyrovský,P. Zuman Pdf

Practical Polarography: An Introduction for Chemistry Students provides information pertinent to the fundamental aspects of practical polarography. This book presents the developments in polarography and provides descriptions and procedures that should be readily available for use with any available polarograph. Organized into eight chapters, this book begins with an overview of polarography that is widely employed in chemical analysis because the current-voltage curves show both the quantitative and qualitative composition of the solution. This text then explains the electrode in polarographic electrolysis, which consists either of a mercury pool at the bottom of the electrolytic cell that contains the solution under test, or of a special type of electrode of known potential. Other chapters consider the polarographic reduction of some metal ions and of some organic substances. The final chapter deals with the tables containing selected data of half-wave potentials measured against a saturated calomel electrode at 20-25°C. This book is a valuable resource for students, technicians, and chemists.

Advances in Linear Free Energy Relationships by N. Chapman Pdf

Louis P. Hammett Mitchill Professor Emeritus of Chemistry, Columbia University My interest in linear free energy relationships began when, just out of graduate school, I read in 1924 the article by Bmnsted and Pedersen which for the first time reported the existence of such a relationship. That interest continues to be an active one and, to judge merely by the extensive biblio graphies contained in the present volume, it is widely shared. To my mind a particularly happy aspect of the existence of linear free energy relationships has been the proof it supplies that one need not suppose that the behavior of nature is hopelessly complicated merely because one cannot find a theoretical reason for supposing it to be otherwise. The effect of a substituent in an organic molecule on rate or equilibrium of reaction involves a fourfold difference between relatively large quantities, a situation which always makes for difficult theory. Yet systematic organic chemistry could hardly have existed were it not true that like changes in structure lead to like changes in reactivity. Linear free energy relationships constitute the quantitative specialisation of this fundamental principle, and they stand indeed more in the office of teacher to theory than in that of learner from it.
