Text extracted from opening pages of book: THE CHEMICAL AGE CHEMICAL DICTIONARY CHEMICAL TERMS LONDON: ERNEST BENN LIMITED 8, BOUVERIE STREET, B. C. 4 i 924 Print, d by Jarrold & Sons, Limited, Norwich PREFACE Y HE vast output of chemical literature at the present time is presenting almost insuperable I difficulties to those who attempt to keep abreast of the rapid advances in chemical science. Not the least of these difficulties is the terminology of the subject, for chemical terms are multiplying at a bewildering rate. Frequently, too, when a new word or expression is coined it is followed up with an abbreviation or symbol by which it is expressed. One has, in fact, only to glance through the abstracts of the English and American Chemical Societies to realise the difficulty. The Chemical Age Dictionary of Chemical Terms has been compiled by experts to meet the needs of all those who have to consult not only original papers or their abstracts but other forms of lit erature as represented by reviews and modern textbooks. It will, therefore, make a direct appeal to all chemists from the student to the director of research. The subjects dealt with include organic, inorganic, physical, analytical and biochemistry. Unfortunately, many chemical terms are loose and even vague and it is very difficult, if not impossible, to give exact definitions in such cases. Indeed, it is undesirable to attempt to give an exact definition where none exists This is especially the case with names by which certain theories or concepts are known. In general the terms will be found in the form in which they are most frequently met with in technical literature, but in order to avoid repetition it has been foundconvenient in some cases to include a number of closely related terms under one general term. Thus, the different types of isomerism are classed together under Isomerism, the different kinds of spectra under Spectrum, and so on. Tide many laws, reactions, etc., are not grouped together under these headings but will be found under the names by which they arc known For example Henry's Law, and not Law of Henry, Hoesch Reaction, and not Reaction, Hoesch van't Hoff factor and not Factor, van't Hoff. In many cases cross-references are given not only to the same subject but to cognate subjects. No effort has been spared to illustrate the explanations and definitions by means of examples; and it is hoped that these will be of great assistance in elucidating terms which could not otherwise be made perfectly clear. The Dictionary is an essential supplement to, but not a substitute for, the textbook. The present dictionary is intended to be the forerunner of successive volumes, each one of which will deal with the subject as it appears in its different phases. Thus, it is hoped to publish a second volume dealing with Organic Substances, a third dealing with Inorganic Substances, etc. No Dictionary compiled on similar lines has as yet appeared in the English language. It is hoped, therefore, that the present volume will prove not only a novelty, but an indispensable companion for all those who are interested in pure chemistry or its application to industry.

Launched in 1995 as a companion to the Dictionary of Organic Compounds, the Organic Chemist’s Desk Reference has been essential reading for laboratory chemists who need a succinct guide to the ‘nuts and bolts’ of organic chemistry — the literature, nomenclature, stereochemistry, spectroscopy, hazard information, and laboratory data. This third edition reflects changes in the dissemination of chemical information, revisions to chemical nomenclature, and the adoption of new techniques in NMR spectroscopy, which have taken place since publication of the last edition in 2011. Organic chemistry embraces many other disciplines — from material sciences to molecular biology — whose practitioners will benefit from the comprehensive but concise information brought together in this book. Extensively revised and updated, this new edition contains the very latest data that chemists need access to for experimentation and research.
The combined chemical dictionary is a structured database holding information on chemical substances. It includes descriptive and numerical data on chemical, physical and biological properties of compounds; systematic and common names of compounds; literature references; structure diagrams and their associated connection tables. The online version contains all those compounds published in: Dictionary of organic compounds (240,000 records); Dictionary of natural Products (155,000 records); Dictionary of inorganic and organometallic compounds (100,000 records); Dictionary of pharmacological agents (38,000 records); and Dictionary of analytical reagents (14,000 records).
