The Chemistry of Synthetic Dyes, Volume VIII PDF by Krishnasami Venkataraman

GENERAL PREFACE
For a few years I considered writing an entirely new edition of “The Chemistry of Synthetic Dyes.” As a result of discussions with many friends and colleagues who are familiar with the two volumes, I decided in 1967 that the urgent need was not for a revision, because very little of the contents of the 1952 publication had become obsolete, but for a review of the subsequent developments.

The progress made in the chemistry of synthetic dyes in the last twenty years has been amazing. The discovery of reactive dyes is one major advance. There has also been extensive research on intermediates, disperse dyes, cationic dyes, cyanine dyes, pigments, and metal complexes, all of which have led to much new chemical knowledge. Consequently I realized that it was no longer possible for a single author to give accurate and authoritative accounts of the progress made in each specialized area of synthetic dyes. I have been fortunate in the response I have had to my invitations to contribute to the additional volumes. All the chapters have been written by acknowledged authorities, whose names are associated with many patents and papers, and who have worked for many years on the topics they have covered.

In addition to the synthesis and application of dyes of all types, fluorescent brightening agents and such fundamental topics as color and electronic states of organic molecules, photochemistry of dyes, physical chemistry of dyeing, and the relation between structure and technical properties are covered.

These volumes are intended primarily for chemists and technologists who are concerned with the synthesis of dyes and their applications, but since most of the chapters constitute essays in synthetic organic chemistry, they should be of interest to organic chemists in general. An important feature is the very thorough coverage and critical assessment of patent literature as well as publications’ in scientific journals. The record of achievement presented in these volumes also indicates the directions of future research.

I am indebted to the authors for accepting my invitation and to the companies who made it possible for their leading scientists to spare the necessary time. The plan for this international multiauthor effort took concrete shape during ten days I spent in the Research Department of Farbenfabriken Bayer. I am grateful to Professor Petersen, Dr. Delfs, and their colleagues, and also to Dr. R. R. Davies (Imperial Chemical Industries, Dyestuffs Division) for their help in the organization of this series. My thanks are due to Mr. J. V. Rajan, Mr. G. V. Kulkarni, and Mr. S. A. Nair for preparing the Subject Indexes, checking literature references, and dealing with the heavy correspondence. Academic Press has handled production problems with its usual efficiency, and it is a pleasure to thank the staff for their cooperation. Finally, I wish to make grateful acknowledgment of the hospitality of the National Chemical Laboratory provided by the Director, Dr. B. D. Tilak, the Director- General of Scientific and Industrial Research, Dr. Y. Nayudamma, and his predecessor Dr. Atma Ram, without which I could not have undertaken this project.
